81-455: The Broadmoor Manitou and Pikes Peak Cog Railway (also known as the Pikes Peak Cog Railway ) is a cog railway that climbs one of the most iconic mountains in the United States, Pikes Peak in Colorado . The base station is in Manitou Springs , near Colorado Springs . Construction on the line was started in 1889 and the first train reached the summit on June 30, 1891. Cog railways are common in Switzerland and found in other parts of

162-471: 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

243-429: 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

324-609: 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

405-490: A complete refurbishment that saw the replacement of the track infrastructure, the rebuild of older railcars and the purchase of three new trainsets. The idea for the railroad came in 1888, after a trip to the summit by inventor Zalmon G. Simmons , who had founded previously the Simmons Bedding Company . Simmons had designed a wooden telegraph insulator while on the board of directors of Western Union , and

486-496: A deal with the city of Manitou Springs that would provide $ 36 million in tax breaks for the railroad over a 50-year period if the company completed the upgrades. The agreement was signed on November 20, 2018. The major refurbishment project would involve the near-complete replacement of the track infrastructure, the rebuild of facilities and older railcars and the purchase of three new trainsets. Starting in March 2019, crews ripped up

567-592: 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

648-504: 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

729-454: A diesel-electric locomotive, two coaches and a control car , and marked a return to locomotive-hauled trains. Additionally, a snowblower (No. 30) was ordered from Stadler's partner, Zaugg AG Eggiwill of Switzerland. The snowblower has a diesel engine to turn its blades, but it is not self-propelled and instead acts as a control car and pushed by one of the Stadler locomotives. In February 2021,

810-465: 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

891-417: A fleet of self-propelled railcars in 1964, purchasing two units (#14 and #15) from Swiss Locomotive and Machine Works (SLM), which would be similar to equipment used on many Swiss cog railways. The air-cooled, 8-cylinder diesel engines in the first units proved to be less than satisfactory on the railroad above the tree line and were replaced by water-cooled engines. The railcars proved to be a good addition to

972-577: 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

1053-421: 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,

1134-486: 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 ,

1215-551: A rockslide in 1990. This line's lower terminus was adjacent to the Cog Railway base station in Manitou Springs. The Manitou Incline averaged almost a 40% grade, gaining 2,011 feet (613 m) in elevation over a length of approximately 1 mile (1.6 km), with the maximum grade being 68%. The Manitou Incline was initially built in 1907 for use in the construction of city water lines and a hydroelectric plant. When

1296-471: A stake in the line. Penrose was the owner of The Broadmoor , a well-known hotel in Colorado Springs. Under the control of Penrose, there was an effort to find more economical ways to operate the line. To that end, gasoline -powered railcar #7 was constructed in 1938. The railcar was intended to be a cheaper alternative to operating steam locomotives during quieter times of the year. The railcar

1377-484: 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

1458-533: 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

1539-502: 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

1620-414: 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

1701-656: 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

1782-723: 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

1863-611: 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

1944-494: 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,

2025-488: 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

2106-1003: 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

2187-406: 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

2268-432: 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),

2349-459: 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

2430-523: 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

2511-600: The CR worked with the South Australian Railways to trial diesel traction. However, the technology was not developed enough to be reliable. 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

2673-895: The Netherlands, and in 1927 in Germany. After a few years of testing, hundreds of units were produced within a decade. 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,

2754-566: The United Kingdom delivered two 1,200 hp (890 kW) locomotives using Sulzer -designed engines to Buenos Aires Great Southern Railway of Argentina. In 1933, diesel–electric technology developed by Maybach was used to propel the DRG Class SVT 877 , a high-speed intercity two-car set, and went into series production with other streamlined car sets in Germany starting in 1935. In the United States, diesel–electric propulsion

2835-499: 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

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

3078-722: 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

3159-420: 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,

3240-449: The cog wheels were wearing out twice as quickly as they did in the 1980s. Winter operations were suspended on October 29, 2017, to conduct maintenance on the railway, but crews soon realized more serious repairs were needed and in March 2018 it was announced that the railway would close indefinitely. The Anschutz Corporation , which owned the railway, estimated a full refurbishment of the line would cost $ 100 million. The company negotiated

From 1990 forward, the defunct Incline had been controversial because, although legally off-limits to the public, its roadbed was heavily used for recreation and exercise by people ignoring the trespassing signs. It became legal to use the Incline on February 1, 2013. Colorado Springs Parks and Recreation manages

3402-422: 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

3483-443: 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

3564-419: 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,

3645-423: 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

3726-456: 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 ,

3807-480: 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

3888-432: The fleet and the railroad purchased two more railcars (#16 and #17) in 1968. As tourism increased in the 1970s the railway needed more capacity. In 1976, the railway took delivery from SLM of two larger railcars (#18 and #19). These are identical in cosmetic appearance to cars 14-17, however consist of two articulated cars. Passing sidings were built at Minnehaha and Windy Point, allowing trains to pass at various points on

3969-569: 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

4050-406: 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

4131-479: The hill. Trains could previously pass only at Mountain View, permitting only three trains a day up the mountain. Eight trains per day became possible with the new equipment and sidings. Two additional two-car trainsets were added in the 1980s (#24 in 1984 and #25 in 1989). By the 2000s, the rail infrastructure was starting to show its age. Railway managers reported that in 2017 the track geometry had become so poor that

4212-570: 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

4293-431: 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

4374-581: 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

4455-546: 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

4536-497: The new equipment was shipped from Switzerland to the United States, arriving in Manitou Springs the next month. Meanwhile, the city of Colorado Springs (which operates the Pikes Peak Highway ) built a new visitor center at the summit, while the railroad built a new platform. Down in Manitou Springs, the depot received a second boarding track and platform. The line reopened on May 20, 2021. The cost has increased over

4617-580: The old manual track switches with radio-controlled versions that would enable faster operations at the passing sidings. While the track work was underway, crews at the railroad shops in Manitou Springs began to rebuild the four two-car SLM railcars (Nos. 18, 19, 24 and 25). Each railcar was converted to the new Strub system, received a new transmission with a retarder for dynamic braking and was repowered with new diesel engines. The railroad also placed an order for three trainsets (Nos. 27, 28 and 29) from Stadler Rail of Switzerland. Each trainset would consist of

4698-399: The old rails, Abt rack system, and wooden ties, some of which had been in place since the line was first built in 1889. Work started at the depot in Manitou Springs and reached the summit in September. In May 2020, crews began working down from the top, laying down metal ties, new rails custom ordered from Poland and a new Strub rack system which featured more robust teeth. Crews also replaced

4779-505: The original locomotives were rebuilt as Vauclain compounds in 1893. Over time, the Vauclain compound technology made the locomotives notoriously difficult to maintain. An additional locomotive was added to the fleet in 1901 and again in 1906. All six steam locomotives were rebuilt in 1912 to similar specifications and would burn slightly under 1 ton of coal per trip. Just before the start of the Great Depression , Spencer Penrose purchased

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

4941-584: 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;

5022-484: 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

5103-450: 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

5184-414: The steeply inclined grades. While most locomotives pull rail cars, these steam engines would push the line's wooden passenger cars up the mountain, decreasing the chance of a runaway car. A fourth steam locomotive was added to the fleet in 1892 (which was built as a Vauclain compound ), which proved to be more efficient and cut the cost of operating on a steep incline. The locomotive was so successful that

5265-405: 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

5346-474: The summit of Pikes Peak at an elevation of 14,115 feet (4,302 m). The average grade of the line would be 12% but would top out at 25%. Normal trains can not retain traction on the rails at grades steeper than 10%, so the railway would need to use a cog and rack system to help pull trains up the mountain and control the speed of the descent. Construction was started in 1889, being built by Italian laborers using only pickaxes and assisted by donkeys. The line

5427-432: 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

5508-479: 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

5589-451: 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

5670-500: The world (totaling about 50 lines), but this is one of only three such lines remaining in the United States, the others being the older Mount Washington Cog Railway in New Hampshire, and the short Quincy and Torch Lake Cog Railway . Originally powered by steam locomotives, the line later switched over to diesel-powered locomotives and self-propelled railcars. The railway was closed between October 29, 2017 and May 20, 2021, for

5751-672: 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

5832-596: The years. In 2023, the price for auto-assigned seatings was USD$ 58.50 (adults) / USD$ 48.50 (age 12 and under); or USD$ 71 / USD$ 61 for reserved seating. More commonly called simply the Manitou Incline , the Mount Manitou Scenic Incline Railway was actually a funicular up the side of a peak called Rocky Mountain located adjacent to Mount Manitou . It was operated by the Manitou and Pike's Peak Railway until its closure following

5913-473: 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,

5994-482: Was a huge success, and led the railroad to purchase five 'streamlined' diesel locomotives from General Electric , which were equipped with matching passenger cars , acquired from 1939 onward. The diesel locomotives slowly supplanted the steam locomotives, though some steam operations persisted until the 1960s as backup power and to operate the snow-clearing train (where their greater weight meant they were less likely to derail). The railroad started switching over to

6075-527: 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

6156-559: Was built as a standard-gauge railway with an Abt rack system and wooden ties . Limited service was started in 1890 on the first segment of the line from Manitou Springs to the Halfway House Hotel. On June 30, 1891, the first train reached the summit. Three steam locomotives were built for the line by the Baldwin Locomotive Works that each featured boilers offset by 16 degrees to keep them level on

6237-688: 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

6318-400: 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

6399-494: Was shown suitable for full-size passenger and freight service. Following their 1925 prototype, the AGEIR consortium produced 25 more units of 300 hp (220 kW) "60 ton" AGEIR boxcab switching locomotives between 1925 and 1928 for several New York City railroads, making them the first series-produced diesel locomotives. The consortium also produced seven twin-engine "100 ton" boxcabs and one hybrid trolley/battery unit with

6480-461: Was surveying Englemann Canyon for telegraph lines to the top of Pikes Peak . It was a miserable two-day trip on a mule and after his return, Simmons was convinced that there needed to be a more "civilized" mode of travel to the summit of Pikes Peak and decided to fund the construction of a railway. The line would start at a depot in the town of Manitou Springs, located at an elevation of 6,320 feet (1,930 m), and climb 8.9 miles (14.3 km) to

6561-737: Was used on the Hull Docks . In 1896, an oil-engined railway locomotive was built for the Royal Arsenal in Woolwich , England, using an engine designed by Herbert Akroyd Stuart . It was not a diesel, because it used a hot-bulb engine (also known as a semi-diesel), but it was the precursor of the diesel. Rudolf Diesel considered using his engine for powering locomotives in his 1893 book Theorie und Konstruktion eines rationellen Wärmemotors zum Ersatz der Dampfmaschine und der heute bekannten Verbrennungsmotoren ( Theory and Construction of
