124-585: The Aerotrain was a streamlined trainset that the General Motors (GM) Electro-Motive Division (EMD) introduced in 1955. GM originally designated the light-weight consist as Train-Y ( Pullman-Standard 's Train-X project was already underway) before the company adopted the Aerotrain marketing name. GM's Styling Section first brought the Aerotrain's train to life, as it did for all of GM's body designs of that mid-century era. Chuck Jordan
248-481: A cab that mimicked an aircraft's cockpit . The locomotive 's overall design was similar to that of General Motors automobiles at the time. The company completed the Aerotrains by coupling each of the two locomotives to sets of ten modified GM Truck & Coach Division (GMC) 40-seat intercity highway bus bodies. Designed to resemble the new PD-4501 Scenicruiser buses that GMC was building for Greyhound ,

In 2015, Eurostar began to operate the electric multiple unit (EMU) British Rail Class 374 , also known as the Eurostar e320, on its high-speed services through the Channel Tunnel . The train serves destinations beyond Eurostar's core routes to the Gare du Nord station in Paris and the Brussels-South railway station . Owned by Eurostar International Limited and capable of operating at 320 km/h (199 mph),
868-456: A new Union Pacific "Railroad". In the early 20th century, Union Pacific's focus shifted from expansion to internal improvement. Recognizing that farmers in the Central and Salinas Valleys of California grew produce far in excess of local markets, Union Pacific worked with its rival Southern Pacific to develop a spoilage-resistant rail-based transport system. These efforts came culminated in

The Tomorrowland train featured cars that were named for the planets while the cars of the Fantasyland train were named after various Disney characters. The modern, streamlined trains were placed in service to represent the future of rail travel in contrast to the steam-powered DRR which represented its past. Motive power for each train consisted of an integral head-end unit driven by an Oldsmobile "Rocket" V8 gasoline engine. Oldsmobile also furnished

#17327975590511488-451: A streamlined design, the Aerotrain s failed to capture the public's imagination. Their cars, based on GM's bus designs and using an air cushioning system, were rough riding and uncomfortable. The design of the locomotive section made routine maintenance difficult and it was underpowered. Originally intended to reach speeds of up to 100 mph (161 km/h) and to travel between New York City and Chicago in 10.5 hours, modifications reduced
1612-547: A streamlined style. The South Manchuria Railway , which was under Japanese control at that time, also designed the Pashina class streamlined locomotive. The Railway operated the Asia Express , whose style was coordinated with that of Pashina locomotives. These streamlined steam locomotives took many man-hours to repair due to their casing. After the outbreak of World War II , the lack of an experienced labor force made
1736-557: A streamlined style. The selected locomotive was No. 43 of class C53. However Hideo Shima , the chief engineer of the conversion, thought streamlining had no practical effect on reducing air resistance, because Japanese trains at that time did not exceed a speed of 62 mph (100 km/h). Shima therefore designed the locomotive to create airflow that lifted exhaust smoke away from the locomotive. He had expected no practical effect on reducing air resistance completely, therefore he never tried to test fuel consumption or tractive force of
1860-453: A style that was as much nautically as aerodynamically inspired. The McKeen cars were unsuccessful because the internal combustion drive technology for that application was unreliable at the time. Further, the lightweight frames dictated by the cars' limited power tended to break. Streamlined rail motorcars would appear again in the early 1930s after the internal combustion-electric propulsion technology that General Electric developed and that
1984-746: A test run from Washington to Newark on the Pennsylvania Railroad while the other traveled in four hours from Chicago to Detroit on the New York Central Railroad . In late February 1956, the Pennsylvania Railroad rented the first train from GM and began operating it between New York City and Pittsburgh as the Pennsy (No. 1000). In June, the Pennsylvania reduced its Aerotrain's route, whereupon

2232-535: A top speed of 112.5 mph (181.1 km/h). This was the fastest authenticated speed reached by a steam locomotive at the time, making #2 the rail speed record holder for steam and the first steam locomotive to top 110 mph (180 km/h). That record lasted until a German DRG Class 05 locomotive exceeded it the following year. The Illinois Central 121 trainset was the first of the Green Diamond streamliners running between Chicago and St Louis. It

The locomotive, custom painted in the colors of GWH Bush's Air Force One is the only UP locomotive not painted in traditional Armour yellow. The engine also pulled the president's funeral train on his final journey to College Station in 2018. The Union Pacific system includes hundreds of yards. Most are flat yards used for local switching. Other types of yards include intermodal terminals and hump yards. Most UP intermodal terminals are typically ports, but UP also has inland terminals for transfers to trucks, such as
2976-612: The Burlington Zephyr . The two railroads' trains each entered service as three-car articulated sets (including the power car). The Winton Engine Corporation , a subsidiary of General Motors (GM) , manufactured the engines for both locomotives. The prime mover for the Burlington Zephyr' s diesel-electric propulsion was a new 600 hp diesel engine. The Union Pacific's M-10000 had a 600-horsepower (450 kW) spark-ignition engine that ran on "petroleum distillate",

Timetables show that the Ohio Xplorer ran in 1956 during
3224-614: The Pioneer Zephyr in honor of that train's status as the first of the fleet. In April 1935, two Twin Cities Zephyrs that bore the same three-car configuration entered service on the railroad's Chicago and Minneapolis-St. Paul route. Larger trainsets with more powerful Winton engines were built for the Burlington and put into service over longer routes. Twin-engine power units and eventually booster power units met

However, due to intense lobbying by Dr. Thomas Clark Durant , the eastern terminal was moved to a location where the Union Pacific could link up with the Mississippi and Missouri Railroad in Iowa. Following the Act's passage, commissioners appointed by Congress began selling stock in
3596-458: The Aerotrain's maximum speed to 80 mph (129 km/h). The Atchison, Topeka and Santa Fe needed a helper locomotive to enable the 1,200 horsepower LWT-12 power car to climb the Sorrento grade outside of San Diego when pulling the Aerotrain's ten coaches as a San Diegan . A Union Pacific LWT-12 later required the assistance of a 1,750 horsepower EMD GP9 switcher locomotive to transport
3720-437: The Aerotrain's passenger cars had windows with slanted sides. The finned back end of the train resembled the rear of a 1955 Chevrolet or Pontiac station wagon. Each car rode on two axles with an air suspension system that was intended to give a smooth ride, but had the opposite effect. GM returned to a concept first used at the start of the streamliner era: semi-permanently coupled trains. The cars were 40 feet long, half

Disputes over trackage rights and passenger revenues with the C&;NW prompted the UP to switch to the Milwaukee Road for the handling of its streamliner trains between Chicago and Omaha beginning in late 1955. The last intercity passenger train operated by UP was the westbound City of Los Angeles , arriving at Los Angeles Union Station on May 2. Since then, Union Pacific has satisfied its common carrier requirements by hosting Amtrak trains. Many Amtrak and commuter rail routes use Union Pacific rails. This list excludes

Streetcar builders sought to build electric cars with improved speed for interurban lines through the 1920s. In 1931, the J. G. Brill Company introduced the Bullet , a lightweight, wind-tunnel designed car with a rounded front that could run either singly or in multiple-unit sets, capable of speeds over 90 mph (145 km/h). Although Depression -era economics cut into sales,

In the course of the derailment, a 90-ton tank car carrying liquified chlorine was punctured. As the chlorine vaporized, a toxic "yellow cloud" formed, killing three and causing 43 hospitalizations. The costs of cleanup and property damaged during
8804-479: The converted locomotive. The Japanese government planned to use this one converted streamline locomotive on the passenger express route between Osaka and Nagoya. The converted locomotive gained much popularity from the public. JGR therefore decided to build 21 new streamlined versions of the class C55 locomotive . Additionally, JGR built 3 streamlined class EF55 electric locomotives. Kiha-43000 diesel multiple units and Moha-52 electric multiple units also received
8928-598: The design was highly successful in service, lasting into the 1980s. In 1925, the recently-formed Pullman Car & Manufacturing Corporation experimented with lightweight self-propelled railcars in co-operation with the Ford Motor Company concurrent with Ford's development of its Trimotor aircraft. In 1931, Pullman enlisted the services of the Trimotor design contributor William Bushnell Stout to apply airplane fuselage design concepts to railcars. The result
9052-646: The earlier EMC 1800 hp B-B development design locomotives, the twin-engine format and multiple-unit control systems that facilitated cab/booster locomotive sets. The E-units brought sufficient power for full-sized trains such as the B&;O Capitol Limited , the Atchison, Topeka and Santa Fe Railway 's (AT&SF's) Super Chief , and the Union Pacific's upgraded City of Los Angeles and City of San Francisco , which challenged steam power in all aspects of passenger service. EMC introduced standardized production to
9176-559: The early postwar era. Among the most distinctive were the Pennsylvania Railroad's duplex-drive 6-4-4-6 type S1 and 4-4-4-4 type T1 locomotives that Raymond Loewy styled. In terms of service longevity, the most successful were the Southern Pacific GS-3 Daylight locomotives introduced in 1938 and the Norfolk and Western class J locomotives introduced in 1941. In contrast to designs that completely encased
9300-572: The extent that the FRA, in a letter to UP's CEO, said "safety of railroad operations is paramount ... decisions that comprise that fundamental ... are unacceptable. You must ensure that highly trained and experienced personnel perform critical inspections and repairs .... Your railroad (layoffs) are far outpacing any of your Class 1 peers." In 2024 the railway celebrated 150 years of having its headquarters in Omaha. The railway's Big Boy #4014,
9424-576: The federally chartered Union Pacific Railroad Company. By 1863, Durant had organized the purchase of 2,000 shares, the prerequisite amount of stock sold in order to begin the railroad's construction. The resulting track ran westward from Council Bluffs, Iowa , to meet in Utah the Central Pacific Railroad line, which had been constructed eastward from Sacramento, California . The combined Union Pacific–Central Pacific line became known as
9548-607: The first trainset joined the second in the Union Pacific's City of Las Vegas service. Dissatisfied with both, the Union Pacific stopped operating the trainsets in September and October 1957. In October, 1958, General Motors sold both trainsets at a discount to the Chicago, Rock Island and Pacific Railroad (the Rock Island line), which designated their locomotives as numbers 2 and 3 while using both trainsets in commuter service between Chicago and Joliet . The two trainsets ended service in 1966, ten years after they first ran. Although
9672-544: The first transcontinental railroad in North America. Leland Stanford, founder of the Central Pacific Railroad which itself eventually was merged with Union Pacific, himself drove the golden spike , inscribed with the words "to span the continent and wed the oceans." Subsequently, the UP purchased three Mormon -built roads: the Utah Central Railroad extending south from Ogden to Salt Lake City ,
9796-463: The following years. After its Worlds Fair display and a nationwide demonstration tour, the Zephyr entered revenue service between Kansas City, Missouri, and Lincoln, Nebraska, on 11 November 1934. A total of nine Zephyr trainsets were built for the Burlington between 1934 and 1939. Each ran as named trains on various Burlington midwestern routes. The Burlington later renamed the Burlington Zephyr as
9920-405: The herald of a new era in rail transportation. On 26 May 1934, the Burlington's Zephyr made a record-breaking "Dawn to Dusk" run from Denver, Colorado , to Chicago for its grand entry as a Century of Progress exhibit. The Zephyr covered the distance in 13 hours, reaching a top speed of 112.5 mph (181.1 km/h) and running an average speed of 77.6 mph (124.9 km/h). The fuel for
10044-473: The high strength alloy stainless steel , enabled by shot welding , a breakthrough in electrical welding technique. The venture produced articulated power-trailer car sets with streamlined styling, which left the Budd Company just a (much) more powerful engine away from producing a history-making streamlined trainset. The Great Depression caused a catastrophic loss of business for the rail industry as
10168-468: The inflated costs on to the United States government. To convince the federal government to accept the increased costs, Crédit Mobilier had bribed multiple congressmen. Several prominent UP board members (including Durant) had been involved in the scheme. The ensuing financial crisis of 1873 led to a credit crunch, but not bankruptcy. As boom followed bust, the Union Pacific continued to expand. A new company, with dominant stockholder Jay Gould , purchased
10292-778: The key advantages of rail travel over the automobile, which became an increasingly attractive alternative as postwar construction of highway systems progressed. Rail operators marketed their services on the basis of luxurious sightseeing, as airlines increasingly competed with rail lines for long-distance travel. In the mid-1950s, there were several attempts to revive the lightweight custom streamliner concept. None of these projects achieved any lasting impact on passenger service. The Train X project, first promoted by Robert R. Young no later than 1948, resulted in low-profile Baldwin RP-210 locomotives paired with articulated aluminum cars from Pullman-Standard . Two trainsets were built in 1956 for
10416-474: The late 1950s brought forth a new round of price competition from airlines for long-distance travel, severely affecting the ridership and profitability of long-distance passenger rail service. Government regulations forced railroads to continue to operate passenger rail service, even on long routes where, the railroads argued, it was almost impossible to make a profit. Union Pacific Railroad The Union Pacific Railroad ( reporting marks UP , UPP , UPY )
10540-560: The length of standard designs, thereby reducing the weight by 50%. To further reduce weight, the locomotives and cars were made of aluminum , rather than steel. On August 22, 1955, Mrs. N.C. Dezendorf, the wife of GM vice-president and EMD general manager N.C. Dezendorf, christened the first Aerotrain trainset (GM-T1) during a press preview of the train that EMD held at its plant in McCook, Illinois (mailing address: La Grange, Illinois ) near Chicago. On January 5, 1956, one Aerotrain made
10664-604: The lightweight carbody construction and raked, rounded front end introduced with the Zephyr and the high-mounted, behind-the-nose cab of the M-1000x locomotives. One of the first, EMC's TA , was a 1,200-horsepower (890 kW) version produced for the Rock Island Rockets , a series of six lightweight, semi-articulated three and four-car trainsets. EMC/EMD manufactured streamlined E-unit diesel-electric locomotives from 1937 to 1963. These incorporated two features of
10788-595: The limitations of the locomotives' technology when meeting the demands of long-distance and higher capacity service. The M-10001 ran for only 32 months as the City of Portland before it was replaced, re-entered service on the Portland–Seattle run and retired in June 1939. Similarly, the M-10002 spent 19 months as the Union Pacific's City of Los Angeles , 39 months as the City of Portland and ten months out of service starting in July 1941. The locomotive then served on
10912-431: The local authorities. According to UP's 2007 Annual Report to Investors, at the end of 2007 it had more than 50,000 employees, 8,721 locomotives, and 94,284 freight cars. Broken down by specific type of car, owned and leased: In addition, it owns 6,950 different pieces of maintenance of way work equipment. At the end of 2007, the average age of UP's locomotive fleet was 14.8 years, the freight car fleet 28 years. UP
11036-549: The locomotive body is painted Armour Yellow , a color used by Armour and Company on the packaging of its meat products. A thin band of Signal Red divides this from the Harbor Mist Gray (a light gray) used for the body and roof above that point. There is also a thin band of Signal Red along the bottom of the locomotive body, but this color has gradually become yellow as new Federal Railroad Administration (FRA) regulations for reflectorized tape came into effect in 2005;
11160-461: The locomotive industry, with its attendant economies of scale and simplified processes for ordering, producing and servicing locomotives. As a result, EMC was able to offer a variety of support services that decreased technological and initial cost barriers that would otherwise deter conversions to diesel-electric power. With power and reliability of new diesel-electric units improved with the 2,000-horsepower (1,500 kW) EMC E3 locomotive in 1938,
11284-423: The names City of Portland (June 1935), City of Los Angeles (May 1936), City of San Francisco (June 1936) and City of Denver (June 1936). The M-10001 set had a single power unit that contained a 1,200-horsepower (890 kW) Winton diesel engine. The power unit pulled six tapered low-profile cars that had the form of the original three-car M-10000 trainset. The M-10002 ' s set consisted of
11408-576: The old on January 24, 1880. Gould already owned the Kansas Pacific (originally called the Union Pacific, Eastern Division, though in essence a separate railroad), and sought to merge it with UP. Through that merger, the original "Union Pacific Rail Road" transformed into "Union Pacific Railway". Extending towards the Pacific Northwest, Union Pacific built or purchased local lines to reach Portland, Oregon . Towards Colorado, it built
11532-730: The original Union Pacific Rail Road was part of the first transcontinental railroad project, later known as the Overland Route . Over the next century, UP absorbed the Missouri Pacific Railroad , the Western Pacific Railroad , the Missouri–Kansas–Texas Railroad and the Chicago, Rock Island and Pacific Railroad . In 1995, the Union Pacific merged with Chicago and North Western Transportation Company , completing its reach into
11656-533: The original Zephyr, entered service between Boston and Portland, Maine , on 1 April 1935. The Gulf, Mobile and Northern Railroad Rebel trainsets were similar to the Zephyr in form, but were not articulated. Designed by Otto Kuhler , the ALCO powered diesel-electrics that the American Car and Foundry Company constructed were placed into service on 10 July 1935. While streamlining on steam locomotives
11780-511: The postwar era. The railroad retired the last of its six-car sets in 1968 after using it as the Nebraska Zephyr . On 31 January 1935, the Union Pacific's three-car M-10000 went into service between Kansas City, Missouri , and Salina, Kansas , as The Streamliner . The train subsequently became the City of Salina under the railroad's naming convention for its expanding fleet of diesel-powered streamliners. The Union Pacific operated
11904-468: The power car as locomotive number 1. The American Car and Foundry Company constructed the Jet Rocket 's coaches, most of which were similar, but not identical, to those of the Talgo II . The last car resembled that of the future Talgo III . Unlike the slanted sides of the windows on the Aerotrain's ten coaches, the windows on the Jet Rocket's twelve coaches had vertical sides. In addition,
12028-471: The problems worse. As a result, many of the locomotives had their casings removed. Streamliner locomotives arrived relatively late in Australia. In 1937 streamlined casings were fitted on four Victorian Railways S class locomotives for the Spirit of Progress service between Melbourne and Albury . Similar casings were then fitted on two Tasmanian Government Railways R class narrow-gauge locomotives for
12152-464: The railways to provide additional mainline trackage for high speed trains. The first experiments with diesel streamliner services in the United Kingdom were the Blue Pullman trains introduced in 1960 and withdrawn in 1973. These provided 90-mile-per-hour (140 km/h) luxury business services, but were marginally successful and ran only a little faster than mainstream services. The Blue Pullman
12276-607: The repainted locomotives do not resemble those that the power cars bore when last serving the Rock Island line. Disneyland operated a scale version of the Aerotrain known as the Viewliner from 1957 to 1959. The Washington Park and Zoo Railway in Portland, Oregon , has operated a scale, diesel-powered replica of the Aerotrain (dubbed the Zooliner ) to transport zoo visitors since 1958. Idlewild Park in Reno, Nevada , operates
12400-485: The run cost US$ 14.64 at 4¢ per U.S. gallon (equivalent to $ 333 and $ 9 per gallon respectively in 2023 after inflation). The Burlington's event was covered live on radio and drew large, cheering crowds as the "silver streak" zipped by. Adding to the sensation of the Zephyr were the striking appearance of its fluted stainless steel bodywork and its raked, rounded, aerodynamic front end that symbolized its modernity. The train's design echoed in steam locomotive styling throughout
12524-579: The second half of 2005 to the summer of 2006, UP unveiled a new set of six EMD SD70ACe locomotives in "Heritage Colors", painted in schemes reminiscent of railroads acquired by the Union Pacific Corporation since the 1980s. The engine numbers match the year that the predecessor railroad became part of the Union Pacific system. The locomotives commemorate the Missouri Pacific with UP 1982 , the Western Pacific with UP 1983 ,
12648-461: The set in 1950. The visual styling of the new trainsets made the existing fleets of locomotives and railcars suddenly look obsolete. Rail lines soon responded by adding streamlined shrouding and varying degrees of mechanical improvement to older locomotives and re-styling heavyweight cars. The first American steam locomotive to receive that treatment was one of the New York Central Railroad 's (NYC's) J-1 Hudson class locomotives built in 1930, which
12772-580: The speed record that the first DMU "Flying Hamburger" had set 1933 traveling between Hamburg and Berlin. A TGV high-speed test train set a world record for the fastest wheeled train, reaching 575 km/h (357 mph) in 2007. Conventional TGV services operate at up to 322 km/h (200 mph) on the LGV Est , LGV Rhin-Rhône and LGV Méditerranée . The power cars of the TGV Euroduplex (2N2) , which began commercial operations in 2011, have
12896-645: The style of the Pennsylvania Railroad 's T1 . In all cases, the streamlining on Australian steam locomotives were purely aesthetic, with negligible impacts on train speeds. In Europe, the streamliner tradition gained new life after World War II . In Germany, DRG Class SVT 137 trains resumed service, but at slower speeds than before the war. Based on the Kruckenberg SVT 137, the Deutsche Bundesbahn 's (DB's) streamlined diesel-electric Class VT 11.5 (later renamed to DB Class 601) built in 1957
13020-614: The terminal in San Antonio that opened in 2009 or the one in Santa Teresa, New Mexico , that opened in 2014. In 2006, Union Pacific had 11 major active hump yards : In the late 2010s, Union Pacific began deactivating hump yards in favor of flat switching. In this, Union Pacific followed the industry-wide trend towards Precision Scheduled Railroading (PSR); railway executive Hunter Harrison explained that under PSR, few yards receive enough variegated traffic to necessitate
13144-590: The trainset traveled only between Philadelphia and Pittsburgh. After the second train’s initial test run on January 5, General Motors demonstrated it on several railroads, including the Atchison, Topeka and Santa Fe Railway , where in April the train operated in California between Los Angeles and San Diego as a San Diegan . In late April, the New York Central began to operate that train in revenue service as
13268-690: The trainsets' additional power requirements. The Burlington's four-car Mark Twain Zephyr entered revenue service in October 1935 on the railroad's Saint Louis– Burlington, Iowa , route. Two partially-articulated six-car trainsets entered service in May 1936 on the Burlington's Denver Zephyr route, which connected Chicago and Denver. The Burlington then replaced those sets with a pair of partially-articulated ten-car trainsets in November 1936. The Burlington moved
13392-479: The trucks (painted Aluminum from 1955 to 1982), underframe, fuel tanks and everything else beneath that line are also Harbor Mist Gray. Lettering and numbering are in Signal Red, with black outlines. Most locomotives have white-outlined blue "wings" on the nose, on either side of the renowned shield featuring white lettering on a blue background and, below it, red and white vertical stripes. Beginning in early 2002,
13516-579: The two Aerotrains that GM constructed are now on display. The National Railroad Museum in Green Bay, Wisconsin , exhibits the Rock Island line's repainted Aerotrain locomotive number 2 and two of its coaches (parts of trainset number 2). The National Museum of Transportation in Kirkwood, Missouri (near St. Louis ) exhibits the Rock Island's similarly repainted Aerotrain locomotive number 3 and two coaches (parts of trainset number 1). The designs on
13640-471: The west coast consisted of five runs monthly for each route. The railroad maintained its daily overnight service on the Chicago–Denver run by assigning three locomotive sets for two trains. The railroad then augmented that stable with locomotive equipment taken from other runs. Despite the breakthrough schedule times of the long-distance M-1000x "City" trains, the records of the Union Pacific's fleet reflected
13764-568: The west. To compete, UP merged with Southern Pacific , thereby incorporating D&RGW and Cotton Belt , and forming a duopoly in the West. The merged railroad took the Union Pacific name. As of 1999, the UP had 33,705 miles (54,243 km) of track, about 33,000 employees, nearly 7,000 locomotives and over 155,000 rail cars. In March 2024 Union Pacific layoffs caused concern at the Federal Railroad Administration to
13888-616: The windscreen, doors and instrument console for each of the two 5,000 lb (2,300 kg) locomotives. The attraction operated until September 15, 1958, when construction began on the Matterhorn and Submarine Voyage ; the Disneyland Monorail System took the place of the Viewliner in June of the following year. The Zooliner , one of three trains on the Washington Park and Zoo Railway operating in
14012-533: The world's largest operating steam locomotive, will visit 14 states in middle America in 2024. Twenty-five locomotives of Big Boy's size were fabricated during World War II, but only Big Boy survives. Its "Heartland of America" tour begins in August 2024 in Cheyenne, Wyoming, and visits Arkansas, Colorado, Illinois, Iowa, Kansas, Missouri, Nebraska, Oklahoma and Texas through October. Another locomotive, UP No. 4141,
14136-604: Was a five-unit (including power car) articulated trainset for day service. The Pullman-built set had the same power format and 1,200-horsepower (890 kW) Winton diesel engine as M-10001, with some style aspects that resembled the later M1000x trainsets. The Illinois Central ran the 121 trainset on the Green Diamond from May 1936 to 1947. After an overhaul, the railroad placed the set on the Jackson Mississippi–New Orleans run until it retired and scrapped
14260-547: Was donated to the George H. W. Bush Presidential Library and Museum on November 8, 2019. On March 31, 2010, UP dedicated a specially painted GE ES44AC locomotive commemorating the centennial of the Boy Scouts of America . On September 28, 2010, UP dedicated a specially painted GE ES44AC locomotive, as a tribute to Susan G. Komen for the Cure . On October 19, 2017, Union Pacific unveiled SD70AH 1943, "The Spirit of
14384-541: Was followed by research into streamlined trains and tilting trains , the first to enter passenger service, in 1976, being the diesel powered InterCity 125 ( Class 43 ), followed by the electric, tilting, British Rail Class 370 , and Class 91 , in combination offering 125 mph (201 km/h) streamlined train services across the United Kingdom. High-speed service with the electric German ICE 1 (Class 401) began in 1991. The train, which has traveled at speeds of up to 280 km/h (174 mph) in revenue service, broke
14508-733: Was in charge of designing the Aerotrain as chief designer of special projects. GM constructed two Aerotrains , each of which used one of the last two (serial numbers 21463 and 21464) of three experimental diesel–electric EMD LWT12 power cars that the company built. GM based the EMD LWT12's power components on those in the EMD SW1200 switcher . Like the SW1200, the LWT12 used the company's model EMD 567C 12-cylinder prime mover that could produce 1,200 horsepower . The power car featured
14632-713: Was incorporated on July 1, 1862, under the Pacific Railroad Act of 1862 . President Abraham Lincoln had approved the act, which authorized railroad construction from the Missouri River to the Pacific to ensure the stability of the Union throughout the American Civil War , but construction did not complete until after the conflict's conclusion. Under the original bill that formed the basis of
14756-422: Was more about marketing than performance, newly designed locomotives with state-of-the-art steam technology were able to travel at high speeds. The Milwaukee Road class A Atlantics , built in 1935 to compete with the Twin Cities Zephyr , were the first "steamliners" equipped to back up their styled claim to extra speed. In a 15 May 1935 run by locomotive No. 2 and a dynamometer car, the railroad documented
14880-490: Was ranked 134th on the 2019 Fortune 500 list of the largest United States corporations by revenue and had 41,967 employees. The Chief Executive Officer of Union Pacific since August 14, 2023, is Jim Vena , the President is Beth Whited, and the chairman of the board is Mike McCarthy. In 2019, Union Pacific has been rated the worst company to work for by 247wallst.com, citing Past CEO Lance Fritz's 12% approval rating and
15004-535: Was re-introduced with streamlined shrouding and named the Commodore Vanderbilt in December 1934. The Vanderbilt styling was a one-off design by Carl Kantola. The NYC's next venture in streamlined styling was Henry Dreyfuss ' 1936 full-length exterior and interior design of the railroad's Mercury trainsets. Raymond Loewy also designed in 1936 art-deco shrouding with a bullet-front scheme for
15128-712: Was sold in 1964. Despite the fact that the M-10000 and its successors were among the first diesel locomotives, Union Pacific completed dieselization relatively late. In 1944, UP finally received delivery of its last steam locomotive: Union Pacific 844 . As the 20th century waned, Union Pacific recognized—like most railroads—that remaining a regional railroad would only lead to bankruptcy. On December 31, 1925, UP and its subsidiaries operated 9,834 miles (15,826 km) routes and 15,265 miles (24,567 km) tracks; in 1980, these numbers had remained roughly constant (9,266 route-miles and 15,647 track-miles). But in 1982, UP acquired
15252-541: Was the Railplane (not the Bennie Railplane ), a streamlined self-propelled railcar with a tapered cross-section, lightweight tubular aluminum space frame and duralumin skin. In testing with the Gulf, Mobile and Northern Railroad in 1932, it reportedly reached 90 mph (145 km/h). The Union Pacific had been seeking improvements to self-propelled railcars based on European design ideas. The performance of
15376-608: Was used as the " Trans Europ Express (TEE)" for international high-speed trains. From 1965, the DB used the streamlined electric locomotives DB Class 103 with regular trains for high-speed service. From 1973, the DB used the DB Class 403 , a fully streamlined four-unit electric train with tilting technology. In East Germany, the DR Class VT 18.16 [ de ] was built for international express service. The Swiss SBB and
