A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine . Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels . The most common are diesel–electric locomotives and diesel–hydraulic.
147-670: The EMD G16 is a diesel locomotive built by General Motors in the US and under licence by Clyde Engineering in Australia and MACOSA in Spain. It has been used in Australia , Brazil , Egyptian Railways , Hong Kong , Israel Railways , Mexico , Spain , Yugoslav Railways and on the successor Croatian Railways , Slovenian Railways , Serbian Railways , Macedonian Railways , Republika Srpska Railways , Kosovo Railways and Railways of
294-471: A consist respond in the same way to throttle position. Binary encoding also helps to minimize the number of trainlines (electrical connections) that are required to pass signals from unit to unit. For example, only four trainlines are required to encode all possible throttle positions if there are up to 14 stages of throttling. North American locomotives, such as those built by EMD or General Electric , have eight throttle positions or "notches" as well as
441-537: A " playboy ", describing his performance in the Senate and the House as "pathetic" on another occasion, saying that he was "smart enough, but he doesn't like the grunt work". Author John T. Shaw acknowledges that while his Senate career is not associated with acts of "historic statesmanship" or "novel political thought," Kennedy made modest contributions as a legislator, drafting more than 300 bills to assist Massachusetts and
588-429: A "reverser" to allow them to operate bi-directionally. Many UK-built locomotives have a ten-position throttle. The power positions are often referred to by locomotive crews depending upon the throttle setting, such as "run 3" or "notch 3". In older locomotives, the throttle mechanism was ratcheted so that it was not possible to advance more than one power position at a time. The engine driver could not, for example, pull
735-528: A 16-645E engine. 57 retired in 2009 and was scrapped in late 2014, while 59 retired in 2018 after suffering serious damage from a collision with a EMD G26 locomotive, being scrapped in 2021. As of 2022, both remaining G16s have retired in Hong Kong; locomotive No. 56 I. B. Trevor is now on display in Hung Hom station since 2024 as part of the “Station Rail Voyage” exhibition. In order to replace steam on

That fall, he enrolled at the Stanford Graduate School of Business and audited classes, but he left after a semester to help his father complete his memoirs as an American ambassador. In early 1941, Kennedy toured South America. Kennedy planned to attend Yale Law School , but canceled when American entry into World War II seemed imminent. In 1940, Kennedy attempted to enter
1029-609: A Rational Heat Motor ). However, the large size and poor power-to-weight ratio of early diesel engines made them unsuitable for propelling land-based vehicles. Therefore, the engine's potential as a railroad prime mover was not initially recognized. This changed as research and development reduced the size and weight of the engine. In 1906, Rudolf Diesel, Adolf Klose and the steam and diesel engine manufacturer Gebrüder Sulzer founded Diesel-Sulzer-Klose GmbH to manufacture diesel-powered locomotives. Sulzer had been manufacturing diesel engines since 1898. The Prussian State Railways ordered
1176-420: A badly burned crewman to the island with a life jacket strap clenched between his teeth. From there, Kennedy and his subordinate, Ensign George Ross, made forays through the coral islands, searching for help. When they encountered an English-speaking native with a canoe, Kennedy carved his location on a coconut shell and requested a boat rescue. Seven days after the collision, with the coconut message delivered,
1323-592: A diesel locomotive from the company in 1909, and after test runs between Winterthur and Romanshorn , Switzerland, the diesel–mechanical locomotive was delivered in Berlin in September 1912. The world's first diesel-powered locomotive was operated in the summer of 1912 on the same line from Winterthur but was not a commercial success. During test runs in 1913 several problems were found. The outbreak of World War I in 1914 prevented all further trials. The locomotive weight
1470-504: A diesel-driven charging circuit. ALCO acquired the McIntosh & Seymour Engine Company in 1929 and entered series production of 300 hp (220 kW) and 600 hp (450 kW) single-cab switcher units in 1931. ALCO would be the pre-eminent builder of switch engines through the mid-1930s and would adapt the basic switcher design to produce versatile and highly successful, albeit relatively low powered, road locomotives. GM, seeing
1617-465: A flashover (also known as an arc fault ), which could result in immediate generator failure and, in some cases, start an engine room fire. Current North American practice is for four axles for high-speed passenger or "time" freight, or for six axles for lower-speed or "manifest" freight. The most modern units on "time" freight service tend to have six axles underneath the frame. Unlike those in "manifest" service, "time" freight units will have only four of

#17327937183841764-577: A major manufacturer of diesel engines for marine and stationary applications, in 1930. Supported by the General Motors Research Division, GM's Winton Engine Corporation sought to develop diesel engines suitable for high-speed mobile use. The first milestone in that effort was delivery in early 1934 of the Winton 201A, a two-stroke , mechanically aspirated , uniflow-scavenged , unit-injected diesel engine that could deliver
1911-485: A nearly imperceptible start. The positioning of the reverser and movement of the throttle together is conceptually like shifting an automobile's automatic transmission into gear while the engine is idling. John F. Kennedy John Fitzgerald Kennedy (May 29, 1917 – November 22, 1963), also known as JFK , was the 35th president of the United States , serving from 1961 until his assassination in 1963. He
2058-508: A philanthropist and socialite. His paternal grandfather, P. J. Kennedy , was an East Boston ward boss and Massachusetts state legislator . Kennedy's maternal grandfather and namesake, John F. Fitzgerald , was a U.S. congressman and two-term mayor of Boston . All four of his grandparents were children of Irish immigrants. Kennedy had an older brother, Joseph Jr. , and seven younger siblings: Rosemary , Kathleen , Eunice , Patricia , Robert , Jean , and Ted . Kennedy's father amassed
2205-537: A politician, and at that time he suffered from extreme shyness. Kennedy found "most of his fellow congressmen boring, preoccupied as they all seemed to be with their narrow political concerns." The arcane House rules and customs, which slowed legislation, exasperated him. Kennedy served in the House for six years, joining the influential Education and Labor Committee and the Veterans' Affairs Committee . He concentrated his attention on international affairs, supporting
2352-484: A preparatory boarding school in Wallingford, Connecticut . Rose had wanted John and Joe Jr. to attend a Catholic school , but Joe Sr. thought that if they were to compete in the political world, they needed to be with boys from prominent Protestant families. John spent his first years at Choate in his older brother's shadow and compensated with rebellious behavior that attracted a clique. Their most notorious stunt
2499-414: A private fortune and established trust funds for his nine children that guaranteed lifelong financial independence. His business kept him away from home for long stretches, but Joe Sr. was a formidable presence in his children's lives. He encouraged them to be ambitious, emphasized political discussions at the dinner table, and demanded a high level of academic achievement. John's first exposure to politics
2646-421: A prototype diesel–electric locomotive for "special uses" (such as for runs where water for steam locomotives was scarce) using electrical equipment from Westinghouse Electric Company . Its twin-engine design was not successful, and the unit was scrapped after a short testing and demonstration period. Industry sources were beginning to suggest "the outstanding advantages of this new form of motive power". In 1929,
2793-486: A real prospect with existing diesel technology. Before diesel power could make inroads into mainline service, the limitations of diesel engines circa 1930 – low power-to-weight ratios and narrow output range – had to be overcome. A major effort to overcome those limitations was launched by General Motors after they moved into the diesel field with their acquisition of the Winton Engine Company ,
2940-458: A result of the first debate. The debates are now considered a milestone in American political history—the point at which the medium of television began to play a dominant role. Kennedy's campaign gained momentum after the first debate, and he pulled slightly ahead of Nixon in most polls. On Election Day, Kennedy defeated Nixon in one of the closest presidential elections of the 20th century. In
3087-469: A senator "the most corrupting job in the world." He complained that they were all too quick to cut deals and please campaign contributors to ensure their political futures. Kennedy, with the luxury of a rich father who could finance his campaigns, could remain independent of any special interest, except for those in his home state of Massachusetts that could align against his reelection. According to Robert Caro , Majority Leader Lyndon Johnson viewed Kennedy as

#17327937183843234-422: A series of televised debates . An estimated 70 million Americans, about two-thirds of the electorate, watched the first debate on September 26. Kennedy had met the day before with the producer to discuss the set design and camera placement. Nixon, just out of the hospital after a painful knee injury, did not take advantage of this opportunity and during the debate looked at the reporters asking questions and not at
3381-416: A series of " teas " at hotels and parlors across Massachusetts to reach out to women voters. In the presidential election, Republican Dwight D. Eisenhower carried Massachusetts by 208,000 votes, but Kennedy narrowly defeated Lodge by 70,000 votes for the Senate seat. The following year, he married Jacqueline Bouvier . Kennedy underwent several spinal operations over the next two years. Often absent from
3528-583: A sizable Black population, Kennedy was not particularly sensitive to the problems of African Americans. Robert Kennedy later reflected, "We weren't thinking of the Negroes of Mississippi or Alabama—what should be done for them. We were thinking of what needed to be done in Massachusetts." Most historians and political scientists who have written about Kennedy refer to his U.S. Senate years as an interlude. According to Robert Dallek , Kennedy called being
3675-463: A standard cab. No.7323 was pictured in 1963 with a standard cab, but appeared in 1974 with a close clearance cab, indicating that this unit was either rebuilt or more probably renumbered. Mexican railroaders nicknamed this locomotive as "Tlaconete", referring to the imperial salamander ; it was the first engine that was painted in the olive green, red and white scheme that was kept until 1987. The Renfe Class 1900, later known as Renfe Class 319 were to

In September 1930, Kennedy, 13 years old, was sent to the Canterbury School in New Milford, Connecticut , for 8th grade. In April 1931, he had an appendectomy , after which he withdrew from Canterbury and recuperated at home. In September 1931, Kennedy started attending Choate ,
3969-421: Is because clutches would need to be very large at these power levels and would not fit in a standard 2.5 m (8 ft 2 in)-wide locomotive frame, or would wear too quickly to be useful. The first successful diesel engines used diesel–electric transmissions , and by 1925 a small number of diesel locomotives of 600 hp (450 kW) were in service in the United States. In 1930, Armstrong Whitworth of
4116-533: Is better able to cope with overload conditions that often destroyed the older types of motors. A diesel–electric locomotive's power output is independent of road speed, as long as the unit's generator current and voltage limits are not exceeded. Therefore, the unit's ability to develop tractive effort (also referred to as drawbar pull or tractive force , which is what actually propels the train) will tend to inversely vary with speed within these limits. (See power curve below). Maintaining acceptable operating parameters
4263-502: Is generally limited to low-powered, low-speed shunting (switching) locomotives, lightweight multiple units and self-propelled railcars . The mechanical transmissions used for railroad propulsion are generally more complex and much more robust than standard-road versions. There is usually a fluid coupling interposed between the engine and gearbox, and the gearbox is often of the epicyclic (planetary) type to permit shifting while under load. Various systems have been devised to minimise

A fourth locomotive (001) was renumbered but is out of service. They no longer carry a type designation, instead they were just numbered 001 to 004. They are used to haul coal and clay trains. Locomotive 661-203 began a rebuilding program in 2008, undertaken by TŽV Gredelj (Croatia) in association with Electro-Motive Diesel ;
4557-436: Is often claimed that television viewers overwhelmingly believed Kennedy, appearing to be the more attractive of the two, had won, while radio listeners (a smaller audience) thought Nixon had defeated him. However, only one poll split TV and radio voters like this and the methodology was poor. Pollster Elmo Roper concluded that the debates raised interest, boosted turnout, and gave Kennedy an extra two million votes, mostly as

4704-414: Is the same as placing an automobile's transmission into neutral while the engine is running. To set the locomotive in motion, the reverser control handle is placed into the correct position (forward or reverse), the brake is released and the throttle is moved to the run 1 position (the first power notch). An experienced engine driver can accomplish these steps in a coordinated fashion that will result in
4851-719: The 1953 Worcester tornado ), except on certain occasions when the national interest was at stake. In 1954, Kennedy voted in favor of the Saint Lawrence Seaway which would connect the Great Lakes to the Atlantic Ocean, despite opposition from Massachusetts politicians who argued that the project would hurt the Port of Boston economically. In 1954, when the Senate voted to condemn Joseph McCarthy for breaking Senate rules and abusing an Army general, Kennedy
4998-858: The American embassy in London , where his father was serving as President Franklin D. Roosevelt 's ambassador to the Court of St. James's . The following year, Kennedy traveled throughout Europe, the Soviet Union , the Balkans , and the Middle East in preparation for his Harvard senior honors thesis. He then went to Berlin, where a U.S. diplomatic representative gave him a secret message about war breaking out soon to pass on to his father, and to Czechoslovakia before returning to London on September 1, 1939,
5145-530: The Boston Council from 1946 to 1955 as district vice chairman, member of the executive board, vice-president, and National Council Representative. To appeal to the large Italian-American voting bloc in Massachusetts, Kennedy delivered a speech in November 1947 supporting a $ 227 million aid package to Italy. He maintained that Italy was in danger from an "onslaught of the communist minority" and that
5292-656: The Burlington Route and Union Pacific used custom-built diesel " streamliners " to haul passengers, starting in late 1934. Burlington's Zephyr trainsets evolved from articulated three-car sets with 600 hp power cars in 1934 and early 1935, to the Denver Zephyr semi-articulated ten car trainsets pulled by cab-booster power sets introduced in late 1936. Union Pacific started diesel streamliner service between Chicago and Portland Oregon in June 1935, and in
5439-723: The Busch-Sulzer company in 1911. Only limited success was achieved in the early twentieth century with internal combustion engined railcars, due, in part, to difficulties with mechanical drive systems. General Electric (GE) entered the railcar market in the early twentieth century, as Thomas Edison possessed a patent on the electric locomotive, his design actually being a type of electrically propelled railcar. GE built its first electric locomotive prototype in 1895. However, high electrification costs caused GE to turn its attention to internal combustion power to provide electricity for electric railcars. Problems related to co-ordinating
5586-611: The Canadian National Railways became the first North American railway to use diesels in mainline service with two units, 9000 and 9001, from Westinghouse. However, these early diesels proved expensive and unreliable, with their high cost of acquisition relative to steam unable to be realized in operating cost savings as they were frequently out of service. It would be another five years before diesel–electric propulsion would be successfully used in mainline service, and nearly ten years before fully replacing steam became
5733-494: The DFH1 , began in 1964 following the construction of a prototype in 1959. In Japan, starting in the 1920s, some petrol–electric railcars were produced. The first diesel–electric traction and the first air-streamed vehicles on Japanese rails were the two DMU3s of class Kiha 43000 (キハ43000系). Japan's first series of diesel locomotives was class DD50 (国鉄DD50形), twin locomotives, developed since 1950 and in service since 1953. In 1914,
5880-499: The Democratic presidential nomination . Though some questioned Kennedy's age and experience, his charisma and eloquence earned him numerous supporters. Kennedy faced several potential challengers, including Senate Majority Leader Lyndon Johnson, Adlai Stevenson II , and Senator Hubert Humphrey . Kennedy traveled extensively to build his support. His campaign strategy was to win several primaries to demonstrate his electability to
6027-473: The Fish and Wildlife Service budget, modernizing reserve-fleet vessels , tax incentives to prevent further business relocations, and the development of hydroelectric and nuclear power in Massachusetts. Kennedy's suggestions for stimulating the region's economy appealed to both parties by offering benefits to business and labor, and promising to serve national defense. Congress would eventually enact most of

6174-569: The National Defense Education Act in 1959 to eliminate the requirement that aid recipients sign a loyalty oath and provide supporting affidavits. Kennedy cast a procedural vote against President Eisenhower's bill for the Civil Rights Act of 1957 and this was considered by some to be an appeasement of Southern Democratic opponents of the bill. Kennedy did vote for Title III of the act, which would have given
6321-864: The Naval Reserve Officer Training School in Chicago and at the Motor Torpedo Boat Squadrons Training Center in Melville, Rhode Island . His first command was PT-101 from December 7, 1942, until February 23, 1943. Unhappy to be assigned to the Panama Canal , far from the fighting, Kennedy appealed to Massachusetts senator David Walsh , who arranged for him to be assigned to the South Pacific . In April 1943, Kennedy
6468-549: The PT-109 crew were rescued. Almost immediately, the PT-109 rescue became a highly publicized event. The story was chronicled by John Hersey in The New Yorker in 1944 (decades later it was the basis of a successful film ). It followed Kennedy into politics and provided a strong foundation for his appeal as a leader. Hersey portrayed Kennedy as a modest, self-deprecating hero. For his courage and leadership, Kennedy

All have now been withdrawn from service but 163 (formerly ER 3361) is preserved at the Israel Railway Museum . In Hong Kong there are four locomotives imported for the Kowloon-Canton Railway . They would later be used by the MTR Corporation upon
6762-488: The Società per le Strade Ferrate del Mediterrano in southern Italy in 1926, following trials in 1924–25. The six-cylinder two-stroke motor produced 440 horsepower (330 kW) at 500 rpm, driving four DC motors, one for each axle. These 44 tonnes (43 long tons; 49 short tons) locomotives with 45 km/h (28 mph) top speed proved quite successful. In 1924, two diesel–electric locomotives were taken in service by
6909-1003: The Soviet railways , almost at the same time: In 1935, Krauss-Maffei , MAN and Voith built the first diesel–hydraulic locomotive, called V 140 , in Germany. Diesel–hydraulics became the mainstream in diesel locomotives in Germany since the German railways (DRG) were pleased with the performance of that engine. Serial production of diesel locomotives in Germany began after World War II. In many railway stations and industrial compounds, steam shunters had to be kept hot during many breaks between scattered short tasks. Therefore, diesel traction became economical for shunting before it became economical for hauling trains. The construction of diesel shunters began in 1920 in France, in 1925 in Denmark, in 1926 in
7056-620: The Truman Doctrine as the appropriate response to the emerging Cold War . He also supported public housing and opposed the Labor Management Relations Act of 1947 , which restricted the power of labor unions. Though not as vocally anti-communist as Joseph McCarthy , Kennedy supported the Immigration and Nationality Act of 1952 , which required communists to register with the government, and he deplored
7203-487: The U.S. House of Representatives from 1947 to 1953. He was subsequently elected to the U.S. Senate , serving as the junior senator for Massachusetts from 1953 to 1960. While in the Senate, Kennedy published his book, Profiles in Courage , which won a Pulitzer Prize . Kennedy ran in the 1960 presidential election . His campaign gained momentum after the first televised presidential debates in American history, and he
7350-505: The U.S. Naval Reserve the following year. During World War II , he commanded PT boats in the Pacific theater . Kennedy's survival following the sinking of PT-109 and his rescue of his fellow sailors made him a war hero and earned the Navy and Marine Corps Medal , but left him with serious injuries. After a brief stint in journalism, Kennedy represented a working-class Boston district in
7497-406: The electrification of the line in 1944. Afterwards, the company kept them in service as boosters until 1965. Fiat claims to have built the first Italian diesel–electric locomotive in 1922, but little detail is available. Several Fiat- TIBB Bo'Bo' diesel–locomotives were built for service on the 950 mm ( 3 ft 1 + 3 ⁄ 8 in ) narrow gauge Ferrovie Calabro Lucane and

Victories over Senator Humphrey in the Wisconsin and West Virginia primaries gave Kennedy momentum as he moved on to the 1960 Democratic National Convention in Los Angeles. When Kennedy entered the convention, he had the most delegates, but not enough to ensure that he would win
7791-583: The " loss of China ." During a speech in Salem, Massachusetts on January 30, 1949, Kennedy denounced Truman and the State Department for contributing to the "tragic story of China whose freedom we once fought to preserve. What our young men had saved [in World War II], our diplomats and our President have frittered away." Having served as a boy scout during his childhood, Kennedy was active in
7938-432: The 1,500 kW (2,000 hp) British Rail 10100 locomotive), though only few have proven successful (such as the 1,342 kW (1,800 hp) DSB Class MF ). In a diesel–electric locomotive , the diesel engine drives either an electrical DC generator (generally, less than 3,000 hp (2,200 kW) net for traction), or an electrical AC alternator-rectifier (generally 3,000 hp net or more for traction),
8085-459: The 1960s, the DC generator was replaced by an alternator using a diode bridge to convert its output to DC. This advance greatly improved locomotive reliability and decreased generator maintenance costs by elimination of the commutator and brushes in the generator. Elimination of the brushes and commutator, in turn, eliminated the possibility of a particularly destructive type of event referred to as
8232-523: The 1990s, starting with the Electro-Motive SD70MAC in 1993 and followed by General Electric's AC4400CW in 1994 and AC6000CW in 1995. The Trans-Australian Railway built 1912 to 1917 by Commonwealth Railways (CR) passes through 2,000 km of waterless (or salt watered) desert terrain unsuitable for steam locomotives. The original engineer Henry Deane envisaged diesel operation to overcome such problems. Some have suggested that

Many civil rights advocates criticized that vote as one which would weaken the act. A final compromise bill, which Kennedy supported, was passed in September 1957. As a senator from Massachusetts, which lacked

As in Europe, the usage of internal combustion engines advanced more readily in self-propelled railcars than in locomotives: A diesel–mechanical locomotive uses a mechanical transmission in a fashion similar to that employed in most road vehicles. This type of transmission
8673-684: The Federation of Bosnia and Herzegovina . The Victorian Railways bought six G16C locomotives locally built by Clyde Engineering , known as the X class . In Brazil 41 locomotives were imported. The first eleven were introduced in 1962 and numbered 601–641, and the remaining thirty locomotives were imported in 1964–66. Thirty-seven locomotives still operate trains on the Vitória a Minas Railroad . EMD supplied Egyptian Railways with 111 G16s in 1960–61 (ER numbers 3301–61) and seventeen G16Ws in 1964–65 (ER numbers 3362–411). 20 60.301–60.320 During

The hearings attracted extensive radio and television coverage where the Kennedy brothers engaged in dramatic arguments with controversial labor leaders, including Jimmy Hoffa , of the Teamsters Union . The following year, Kennedy introduced a bill to prevent the expenditure of union dues for improper purposes or private gain; to forbid loans from union funds for illicit transactions; and to compel audits of unions, which would ensure against false financial reports.

Diesel-powered or "oil-engined" railcars, generally diesel–mechanical, were developed by various European manufacturers in the 1930s, e.g. by William Beardmore and Company for the Canadian National Railways (the Beardmore Tornado engine was subsequently used in the R101 airship). Some of those series for regional traffic were begun with gasoline motors and then continued with diesel motors, such as Hungarian BC (The class code doesn't tell anything but "railmotor with 2nd and 3rd class seats".), 128 cars built 1926–1937, or German Wismar railbuses (57 cars 1932–1941). In France,

Celeste, with 73.6 percent of the vote, the largest winning margin in the history of Massachusetts politics. In the aftermath of his re-election, Kennedy began preparing to run for president by traveling throughout the U.S. with the aim of building his candidacy for 1960. On January 2, 1960, Kennedy announced his candidacy for
9555-484: The Pacific. He oversaw a professional advertising campaign that ensured ads went up in just the right places the campaign had a virtual monopoly on [Boston] subway space, and on window stickers ("Kennedy for Congress") for cars and homes and was the force behind the mass mailing of Hersey's PT-109 article. Though Republicans took control of the House in the 1946 elections , Kennedy defeated his Republican opponent in

10290-427: The War Production Board put a halt to building new passenger equipment and gave naval uses priority for diesel engine production. During the petroleum crisis of 1942–43 , coal-fired steam had the advantage of not using fuel that was in critically short supply. EMD was later allowed to increase the production of its FT locomotives and ALCO-GE was allowed to produce a limited number of DL-109 road locomotives, but most in
10437-467: The Warrior River at Choiseul Island , taking ten marines aboard and delivering them to safety. Under doctor's orders, Kennedy was relieved of his command on November 18, and sent to the hospital on Tulagi. By December 1943, with his health deteriorating, Kennedy left the Pacific front and arrived in San Francisco in early January 1944. After receiving treatment for his back injury at the Chelsea Naval Hospital in Massachusetts from May to December 1944, he
10584-701: The army's Officer Candidate School . Despite months of training, he was medically disqualified due to his chronic back problems. On September 24, 1941, Kennedy, with the help of the director of the Office of Naval Intelligence (ONI) and the former naval attaché to Joe Sr., Alan Kirk, joined the United States Naval Reserve . He was commissioned an ensign on October 26, 1941, and joined the ONI staff in Washington, D.C. In January 1942, Kennedy
10731-433: The axles connected to traction motors, with the other two as idler axles for weight distribution. In the late 1980s, the development of high-power variable-voltage/variable-frequency (VVVF) drives, or "traction inverters", allowed the use of polyphase AC traction motors, thereby also eliminating the motor commutator and brushes. The result is a more efficient and reliable drive that requires relatively little maintenance and
10878-426: The base of Kolombangara around 2:00 a.m., and attempted to turn to attack, when PT-109 was rammed suddenly at an angle and cut in half by the destroyer Amagiri , killing two PT-109 crew members. Avoiding surrender, the remaining crew swam towards Plum Pudding Island , 3.5 miles (5.6 km) southwest of the remains of PT-109 , on August 2. Despite re-injuring his back in the collision, Kennedy towed
11025-722: The benefits of an electric locomotive without the railroad having to bear the sizeable expense of electrification. The unit successfully demonstrated, in switching and local freight and passenger service, on ten railroads and three industrial lines. Westinghouse Electric and Baldwin collaborated to build switching locomotives starting in 1929. However, the Great Depression curtailed demand for Westinghouse's electrical equipment, and they stopped building locomotives internally, opting to supply electrical parts instead. In June 1925, Baldwin Locomotive Works outshopped
11172-436: The bogies and traction motors were retained, but with a new frame and engine ( EMD 8-710G3A ). The locomotives were also converted to twin cab designs. The resulting new loco has EMD model code JT38CW-DC. Diesel locomotive Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to
11319-420: The break in transmission during gear changing, such as the S.S.S. (synchro-self-shifting) gearbox used by Hudswell Clarke . Diesel–mechanical propulsion is limited by the difficulty of building a reasonably sized transmission capable of coping with the power and torque required to move a heavy train. A number of attempts to use diesel–mechanical propulsion in high power applications have been made (for example,
11466-440: The camera. Kennedy wore a blue suit and shirt to cut down on glare and appeared sharply focused against the gray studio background. Nixon wore a light-colored suit that blended into the gray background; in combination with the harsh studio lighting that left Nixon perspiring, he offered a less-than-commanding presence. By contrast, Kennedy appeared relaxed, tanned, and telegenic, looking into the camera whilst answering questions. It
11613-674: The campus newspaper, but had little involvement with campus politics, preferring to concentrate on athletics and his social life. Kennedy played football and was on the JV squad during his sophomore year, but an injury forced him off the team, and left him with back problems that plagued him for the rest of his life. He won membership in the Hasty Pudding Club and the Spee Club , one of Harvard's elite " final clubs ". In July 1938, Kennedy sailed overseas with his older brother to work at
11760-608: The country was the "initial battleground in the communist drive to capture Western Europe." To combat Soviet efforts to take control in Middle Eastern and Asian countries like Indochina , Kennedy wanted the United States to develop nonmilitary techniques of resistance that would not create suspicions of neoimperialism or add to the country's financial burden. The problem, as he saw it, was not simply to be anti-communist but to stand for something that these emerging nations would find appealing. Almost every weekend that Congress
11907-537: The day that Germany invaded Poland ; the start of World War II . Two days later, the family was in the House of Commons for speeches endorsing the United Kingdom's declaration of war on Germany. Kennedy was sent as his father's representative to help with arrangements for American survivors of the torpedoing of SS Athenia before flying back to the U.S. on his first transatlantic flight. While Kennedy
12054-422: The design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band , and while low-power gasoline engines could be coupled to mechanical transmissions , the more powerful diesel engines required the development of new forms of transmission. This
12201-500: The early 1990s. None remain in active service. In Serbia, Bosnia and Herzegovina, North Macedonia and Slovenia have all kept the JŽ-era designation series 661. Today there are around fifteen operational series 661s on Serbian Railways. Those locomotives are used mostly on non-electrified railways, primarily to haul freight trains, but also international passenger trains. In Slovenia, the last 661 series locomotive ran on 17 May 2013, and it
12348-443: The engine governor and electrical or electronic components, including switchgear , rectifiers and other components, which control or modify the electrical supply to the traction motors. In the most elementary case, the generator may be directly connected to the motors with only very simple switchgear. Originally, the traction motors and generator were DC machines. Following the development of high-capacity silicon rectifiers in
12495-419: The engine and traction motor with a single lever; subsequent improvements were also patented by Lemp. Lemp's design solved the problem of overloading and damaging the traction motors with excessive electrical power at low speeds, and was the prototype for all internal combustion–electric drive control systems. In 1917–1918, GE produced three experimental diesel–electric locomotives using Lemp's control design,
12642-423: The engine driver operates the controls. When the throttle is in the idle position, the prime mover receives minimal fuel, causing it to idle at low RPM. In addition, the traction motors are not connected to the main generator and the generator's field windings are not excited (energized) – the generator does not produce electricity without excitation. Therefore, the locomotive will be in "neutral". Conceptually, this
12789-738: The failed Bay of Pigs Invasion and Operation Mongoose . In October 1962, U.S. spy planes discovered Soviet missile bases had been deployed in Cuba. The resulting period of tensions, termed the Cuban Missile Crisis , nearly resulted in nuclear war . In August 1961, after East German troops erected the Berlin Wall , Kennedy sent an army convoy to reassure West Berliners of U.S. support, and delivered one of his most famous speeches in West Berlin in June 1963. In 1963, Kennedy signed
12936-610: The fall general election campaign, the Republican nominee and incumbent Vice President Richard Nixon held a six-point lead in the polls. Major issues included how to get the economy moving again, Kennedy's Catholicism, the Cuban Revolution , and whether the space and missile programs of the Soviet Union had surpassed those of the U.S. To address fears that his being Catholic would impact his decision-making, he told
13083-743: The first nuclear weapons treaty . He presided over the establishment of the Peace Corps , Alliance for Progress with Latin America, and the continuation of the Apollo program with the goal of landing a man on the Moon before 1970. He supported the civil rights movement but was only somewhat successful in passing his New Frontier domestic policies. On November 22, 1963, Kennedy was assassinated in Dallas . His vice president, Lyndon B. Johnson , assumed
13230-456: The first diesel railcar was Renault VH , 115 units produced 1933/34. In Italy, after six Gasoline cars since 1931, Fiat and Breda built a lot of diesel railmotors, more than 110 from 1933 to 1938 and 390 from 1940 to 1953, Class 772 known as Littorina , and Class ALn 900. In the 1930s, streamlined highspeed diesel railcars were developed in several countries: In 1945, a batch of 30 Baldwin diesel–electric locomotives, Baldwin 0-6-6-0 1000 ,
13377-480: The first known to be built in the United States. Following this development, the 1923 Kaufman Act banned steam locomotives from New York City, because of severe pollution problems. The response to this law was to electrify high-traffic rail lines. However, electrification was uneconomical to apply to lower-traffic areas. The first regular use of diesel–electric locomotives was in switching (shunter) applications, which were more forgiving than mainline applications of
13524-569: The following year would add Los Angeles, CA , Oakland, CA , and Denver, CO to the destinations of diesel streamliners out of Chicago. The Burlington and Union Pacific streamliners were built by the Budd Company and the Pullman-Standard Company , respectively, using the new Winton engines and power train systems designed by GM's Electro-Motive Corporation . EMC's experimental 1800 hp B-B locomotives of 1935 demonstrated
13671-406: The freight market including their own F series locomotives. GE subsequently dissolved its partnership with ALCO and would emerge as EMD's main competitor in the early 1960s, eventually taking the top position in the locomotive market from EMD. Early diesel–electric locomotives in the United States used direct current (DC) traction motors but alternating current (AC) motors came into widespread use in
13818-408: The general election, taking 73 percent of the vote. As a congressman, Kennedy had a reputation for not taking much interest in the running of his office or his constituents' concerns, with one of the highest absenteeism rates in the House, although much was explained by illness. George Smathers , one of his few political friends at the time, claimed that he was more interested in being a writer than
13965-627: The general public can only regard it as a tragedy that politics has prevented the recommendations of the McClellan committee from being carried out this year," Kennedy announced. That same year, Kennedy joined the Senate's Foreign Relations Committee . There he supported Algeria's effort to gain independence from France and sponsored an amendment to the Mutual Defense Assistance Act that would provide aid to Soviet satellite nations. Kennedy also introduced an amendment to
14112-514: The general public. His personal life has been the focus of considerable sustained interest following public revelations in the 1970s of his chronic health ailments and extramarital affairs . Kennedy is the most recent U.S. president to have died in office . John Fitzgerald Kennedy was born outside Boston in Brookline, Massachusetts , on May 29, 1917, to Joseph P. Kennedy Sr. , a businessman and politician, and Rose Kennedy ( née Fitzgerald),
14259-570: The limitations of contemporary diesel technology and where the idling economy of diesel relative to steam would be most beneficial. GE entered a collaboration with the American Locomotive Company (ALCO) and Ingersoll-Rand (the "AGEIR" consortium) in 1924 to produce a prototype 300 hp (220 kW) "boxcab" locomotive delivered in July 1925. This locomotive demonstrated that the diesel–electric power unit could provide many of
14406-431: The locomotive business were restricted to making switch engines and steam locomotives. In the early postwar era, EMD dominated the market for mainline locomotives with their E and F series locomotives. ALCO-GE in the late 1940s produced switchers and road-switchers that were successful in the short-haul market. However, EMD launched their GP series road-switcher locomotives in 1949, which displaced all other locomotives in
14553-401: The merger. The first three were built by EMD in the US, introduced in 1961 and numbered 56–58. The fourth was built by Clyde Engineering in Australia, introduced in 1966 and numbered 59. They were named I.B. Trevor , Bobby Howes , Gordon Graham , and Gerry Forsgate respectively. All were equipped with 16-567C engines and Co-Co wheel arrangements. 59 suffered a collision and was rebuilt with
14700-525: The mid-1950s. Generally, diesel traction in Italy was of less importance than in other countries, as it was amongst the most advanced countries in the electrification of the main lines and as Italian geography makes freight transport by sea cheaper than rail transportation even on many domestic connections. Adolphus Busch purchased the American manufacturing rights for the diesel engine in 1898 but never applied this new form of power to transportation. He founded
14847-546: The multiple-unit control systems used for the cab/booster sets and the twin-engine format used with the later Zephyr power units. Both of those features would be used in EMC's later production model locomotives. The lightweight diesel streamliners of the mid-1930s demonstrated the advantages of diesel for passenger service with breakthrough schedule times, but diesel locomotive power would not fully come of age until regular series production of mainline diesel locomotives commenced and it
14994-523: The national popular vote, by most accounts , Kennedy led Nixon by just two-tenths of one percent (49.7% to 49.5%), while in the Electoral College , he won 303 votes to Nixon's 219 (269 were needed to win). Fourteen electors from Mississippi and Alabama refused to support Kennedy because of his support for the civil rights movement ; they voted for Senator Harry F. Byrd of Virginia, as did an elector from Oklahoma. Forty-three years old, Kennedy
15141-495: The nations of the world to join to fight what he called the "common enemies of man: tyranny, poverty, disease, and war itself." He added: All this will not be finished in the first one hundred days. Nor will it be finished in the first one thousand days, nor in the life of this Administration, nor even perhaps in our lifetime on this planet. But let us begin." In closing, he expanded on his desire for greater internationalism: "Finally, whether you are citizens of America or citizens of
15288-425: The nomination. Stevenson—the 1952 and 1956 presidential nominee—remained very popular, while Johnson also hoped to win the nomination with support from party leaders. Kennedy's candidacy also faced opposition from former President Harry S. Truman , who was concerned about Kennedy's lack of experience. Kennedy knew that a second ballot could give the nomination to Johnson or someone else, and his well-organized campaign
15435-517: The numerous light rail branches operated by the Nacionales de Mexico (N de M), EMD export models G12 and G16 were obtained. A total of 24 G16 units were built by EMD for the N de M, all equipped with dynamic brakes and introduced between August 1958 and July 1960, their running numbers being 7300 to 7323. The first thirteen units (Nr. 7300 to 7312) had close clearance cabs, and the last eleven units (Nr. 7313 to 7323) were delivered in 1960 and received
15582-402: The output of which provides power to the traction motors that drive the locomotive. There is no mechanical connection between the diesel engine and the wheels. The important components of diesel–electric propulsion are the diesel engine (also known as the prime mover ), the main generator/alternator-rectifier, traction motors (usually with four or six axles), and a control system consisting of
15729-584: The performance and reliability of the new 567 model engine in passenger locomotives, EMC was eager to demonstrate diesel's viability in freight service. Following the successful 1939 tour of EMC's FT demonstrator freight locomotive set, the stage was set for dieselization of American railroads. In 1941, ALCO-GE introduced the RS-1 road-switcher that occupied its own market niche while EMD's F series locomotives were sought for mainline freight service. The US entry into World War II slowed conversion to diesel;
15876-598: The presidency . Lee Harvey Oswald was arrested for the assassination, but he was shot and killed by Jack Ruby two days later. The FBI and the Warren Commission both concluded Oswald had acted alone, but conspiracy theories about the assassination persist. After Kennedy's death, Congress enacted many of his proposals, including the Civil Rights Act of 1964 and the Revenue Act of 1964 . Kennedy ranks highly in polls of U.S. presidents with historians and
16023-468: The presidency. After Joe's death, the assignment fell to JFK as the second eldest. Boston mayor Maurice J. Tobin discussed the possibility of John becoming his running mate in 1946 as a candidate for Massachusetts lieutenant governor , but Joe Sr. preferred a congressional campaign that could send John to Washington, where he could have national visibility. At the urging of Kennedy's father, U.S. Representative James Michael Curley vacated his seat in
16170-467: The presidential nomination, Kennedy gave his well-known " New Frontier " speech: For the problems are not all solved and the battles are not all won—and we stand today on the edge of a New Frontier. ... But the New Frontier of which I speak is not a set of promises—it is a set of challenges. It sums up not what I intend to offer the American people, but what I intend to ask of them. At the start of
16317-484: The prime mover and electric motor were immediately encountered, primarily due to limitations of the Ward Leonard current control system that had been chosen. GE Rail was formed in 1907 and 112 years later, in 2019, was purchased by and merged with Wabtec . A significant breakthrough occurred in 1914, when Hermann Lemp , a GE electrical engineer, developed and patented a reliable control system that controlled
16464-581: The program. Kennedy, a Massachusetts Audubon Society supporter, wanted to make sure that the shorelines of Cape Cod remained unsullied by industrialization. On September 3, 1959, Kennedy co-sponsored the Cape Cod National Seashore bill with his Republican colleague Senator Leverett Saltonstall . As a senator, Kennedy quickly won a reputation for responsiveness to requests from constituents (i.e., co-sponsoring legislation to provide federal loans to help rebuild communities damaged by
16611-450: The required performance for a fast, lightweight passenger train. The second milestone, and the one that got American railroads moving towards diesel, was the 1938 delivery of GM's Model 567 engine that was designed specifically for locomotive use, bringing a fivefold increase in life of some mechanical parts and showing its potential for meeting the rigors of freight service. Diesel–electric railroad locomotion entered mainline service when
16758-585: The school yearbook and was voted the "most likely to succeed." Kennedy intended to study under Harold Laski at the London School of Economics , as his older brother had done. Ill health forced his return to the U.S. in October 1935, when he enrolled late at Princeton University , but had to leave after two months due to gastrointestinal illness. In September 1936, Kennedy enrolled at Harvard College . He wrote occasionally for The Harvard Crimson ,
16905-592: The southern tip of the Solomon's Kolombangara Island. Intelligence had been sent to Kennedy's Commander Thomas G. Warfield expecting the arrival of the large Japanese naval force that would pass on the evening of August 1. Of the 24 torpedoes fired that night by eight of the American PTs, not one hit the Japanese convoy. On that moonless night, Kennedy spotted a Japanese destroyer heading north on its return from
17052-566: The start of his first term, Kennedy focused on fulfilling the promise of his campaign to do "more for Massachusetts" than his predecessor. Although Kennedy's and Lodge's legislative records were similarly liberal, Lodge voted for the Taft-Hartley Act of 1947 and Kennedy voted against it. On NBC 's Meet the Press , Kennedy excoriated Lodge for not doing enough to prevent the increasing migration of manufacturing jobs from Massachusetts to
17199-552: The state delegation to the party's presidential nominee, Adlai Stevenson II , at the Democratic National Convention in August. Stevenson let the convention select the vice presidential nominee . Kennedy finished second in the balloting, losing to Senator Estes Kefauver of Tennessee, but receiving national exposure. In 1957, Kennedy joined the Senate's Select Committee on Labor Rackets (also known as
17346-737: The strongly Democratic 11th congressional district of Massachusetts to become mayor of Boston in 1946. Kennedy established legal residency at 122 Bowdoin Street across from the Massachusetts State House . Kennedy won the Democratic primary with 42 percent of the vote, defeating nine other candidates. According to Fredrik Logevall, Joe Sr. spent hours on the phone with reporters and editors, seeking information, trading confidences, and cajoling them into publishing puff pieces on John, ones that invariably played up his war record in
17493-405: The success of the custom streamliners, sought to expand the market for diesel power by producing standardized locomotives under their Electro-Motive Corporation . In 1936, EMC's new factory started production of switch engines. In 1937, the factory started producing their new E series streamlined passenger locomotives, which would be upgraded with more reliable purpose-built engines in 1938. Seeing
17640-432: The throttle from notch 2 to notch 4 without stopping at notch 3. This feature was intended to prevent rough train handling due to abrupt power increases caused by rapid throttle motion ("throttle stripping", an operating rules violation on many railroads). Modern locomotives no longer have this restriction, as their control systems are able to smoothly modulate power and avoid sudden changes in train loading regardless of how
17787-479: The throttle setting, as determined by the engine driver and the speed at which the prime mover is running (see Control theory ). Locomotive power output, and therefore speed, is typically controlled by the engine driver using a stepped or "notched" throttle that produces binary -like electrical signals corresponding to throttle position. This basic design lends itself well to multiple unit (MU) operation by producing discrete conditions that assure that all units in
17934-451: The use of an internal combustion engine in a railway locomotive is the prototype designed by William Dent Priestman , which was examined by William Thomson, 1st Baron Kelvin in 1888 who described it as a " Priestman oil engine mounted upon a truck which is worked on a temporary line of rails to show the adaptation of a petroleum engine for locomotive purposes." In 1894, a 20 hp (15 kW) two-axle machine built by Priestman Brothers
18081-539: The war and its origins, and quickly became a bestseller. In addition to addressing Britain's unwillingness to strengthen its military in the lead-up to the war, the book called for an Anglo-American alliance against the rising totalitarian powers. Kennedy became increasingly supportive of U.S. intervention in World War II, and his father's isolationist beliefs resulted in the latter's dismissal as ambassador. In 1940, Kennedy graduated cum laude from Harvard with
18228-672: The world's first functional diesel–electric railcars were produced for the Königlich-Sächsische Staatseisenbahnen ( Royal Saxon State Railways ) by Waggonfabrik Rastatt with electric equipment from Brown, Boveri & Cie and diesel engines from Swiss Sulzer AG . They were classified as DET 1 and DET 2 ( de.wiki ). Because of a shortage of petrol products during World War I, they remained unused for regular service in Germany. In 1922, they were sold to Swiss Compagnie du Chemin de fer Régional du Val-de-Travers , where they were used in regular service up to
18375-473: Was 95 tonnes and the power was 883 kW (1,184 hp) with a maximum speed of 100 km/h (62 mph). Small numbers of prototype diesel locomotives were produced in a number of countries through the mid-1920s. One of the first domestically developed Diesel vehicles of China was the Dongfeng DMU (东风), produced in 1958 by CSR Sifang . Series production of China's first Diesel locomotive class,
18522-533: Was a friend of William Randolph Hearst , arranged a position for his son as a special correspondent for Hearst Newspapers ; the assignment kept Kennedy's name in the public eye and "expose[d] him to journalism as a possible career." That May he went to Berlin as a correspondent, covering the Potsdam Conference and other events. Kennedy's elder brother Joe Jr. had been the family's political standard-bearer and had been tapped by their father to seek
18669-509: Was able to earn the support of just enough delegates to win the presidential nomination on the first ballot. Kennedy ignored the opposition of his brother Robert, who wanted him to choose labor leader Walter Reuther , and other liberal supporters when he chose Johnson as his vice-presidential nominee. He believed that the Texas senator could help him win support from the South . In accepting
18816-550: Was an upperclassman at Harvard, he began to take his studies more seriously and developed an interest in political philosophy . He made the dean's list in his junior year. In 1940, Kennedy completed his thesis, "Appeasement in Munich", about British negotiations during the Munich Agreement . The thesis was released on July 24, under the title Why England Slept . The book was one of the first to offer information about
18963-581: Was assigned to Motor Torpedo Squadron TWO, and on April 24 he took command of PT-109 , then based on Tulagi Island in the Solomons . On the night of August 1–2, in support of the New Georgia campaign , PT-109 and fourteen other PTs were ordered to block or repel four Japanese destroyers and floatplanes carrying food, supplies, and 900 Japanese soldiers to the Vila Plantation garrison on
19110-499: Was assigned to the ONI field office at Headquarters, Sixth Naval District , in Charleston, South Carolina . His hope was to be the commander of a PT (patrol torpedo) boat , but his health problems seemed almost certain to prevent active duty. Kennedy's father intervened by providing misleading medical records and convincing PT officers that his presence would bring publicity to the fleet. Kennedy completed six months of training at
19257-457: Was awarded the Navy and Marine Corps Medal , and the injuries he suffered during the incident qualified him for a Purple Heart . After a month's recovery Kennedy returned to duty, commanding the PT-59 . On November 2, Kennedy's PT-59 took part with two other PTs in the rescue of 40–50 marines. The 59 acted as a shield from shore fire as they escaped on two rescue landing craft at the base of
19404-527: Was brought to high-speed mainline passenger service in late 1934, largely through the research and development efforts of General Motors dating back to the late 1920s and advances in lightweight car body design by the Budd Company . The economic recovery from World War II hastened the widespread adoption of diesel locomotives in many countries. They offered greater flexibility and performance than steam locomotives , as well as substantially lower operating and maintenance costs. The earliest recorded example of
19551-627: Was delivered from the United States to the railways of the Soviet Union. In 1947, the London, Midland and Scottish Railway (LMS) introduced the first of a pair of 1,600 hp (1,200 kW) Co-Co diesel–electric locomotives (later British Rail Class D16/1 ) for regular use in the United Kingdom, although British manufacturers such as Armstrong Whitworth had been exporting diesel locomotives since 1930. Fleet deliveries to British Railways, of other designs such as Class 20 and Class 31, began in 1957. Series production of diesel locomotives in Italy began in
19698-565: Was easy. They cut my PT boat in half." On August 12, 1944, Kennedy's older brother, Joe Jr. , a navy pilot, was killed on an air mission. His body was never recovered. The news reached the family's home in Hyannis Port, Massachusetts, a day later. Kennedy felt that Joe Jr.'s reckless flight was partly an effort to outdo him. To console himself, Kennedy set out to assemble a privately published book of remembrances of his brother, As We Remember Joe . In April 1945, Kennedy's father, who
19845-663: Was elected president, narrowly defeating Republican opponent Richard Nixon , the incumbent vice president. Kennedy's presidency saw high tensions with communist states in the Cold War. He increased the number of American military advisers in South Vietnam , and the Strategic Hamlet Program began during his presidency. In 1961, he authorized attempts to overthrow the Cuban government of Fidel Castro in
19992-417: Was exploding a toilet seat with a firecracker. In the next chapel assembly, the headmaster, George St. John, brandished the toilet seat and spoke of "muckers" who would "spit in our sea," leading Kennedy to name his group "The Muckers Club," which included roommate and lifelong friend Lem Billings . Kennedy graduated from Choate in June 1935, finishing 64th of 112 students. He had been the business manager of
20139-479: Was in session, Kennedy would fly back to Massachusetts to give speeches to veteran, fraternal, and civic groups, while maintaining an index card file on individuals who might be helpful for a campaign for statewide office. Contemplating whether to run for Massachusetts governor or the U.S. Senate , Kennedy abandoned interest in the former, believing that the governor "sat in an office, handing out sewer contracts." As early as 1949, Kennedy began preparing to run for
20286-584: Was one of the most used diesel locomotives in Yugoslavia. The type is colloquially nicknamed "Kenedi" after the US President John F. Kennedy . After the breakup in 1991, the locomotives were passed on to successor states: In Croatia the locomotive is classified HŽ series 2061 . As of 2007, the series has been withdrawn from service. Six units of the series were modified by removing two of the traction engines into series 2043 locomotives during
20433-400: Was one of the principal design considerations that had to be solved in early diesel–electric locomotive development and, ultimately, led to the complex control systems in place on modern units. The prime mover's power output is primarily determined by its rotational speed ( RPM ) and fuel rate, which are regulated by a governor or similar mechanism. The governor is designed to react to both
20580-574: Was released from active duty. Beginning in January 1945, Kennedy spent three months recovering from his back injury at Castle Hot Springs , a resort and temporary military hospital in Arizona. On March 1, 1945, Kennedy retired from the Navy Reserve on physical disability and was honorably discharged with the full rank of lieutenant. When later asked how he became a war hero, Kennedy joked: "It
20727-494: Was shown suitable for full-size passenger and freight service.
