USRA Standard
The USRA standard locomotives and railroad cars were designed by the United States Railroad Administration, the nationalized rail system of the United States during World War I. 1,856 steam locomotives and over 100,000 railroad cars were built to these designs during the USRA's tenure. The locomotive designs in particular were the nearest the American railroads and locomotive builders ever got to standard locomotive types, and after the USRA was dissolved in 1920 many of the designs were duplicated in number, 3,251 copies being constructed overall. The last steam locomotive built for a Class I railroad in the United States, an 0-8-0 built by the Norfolk and Western Railway in 1953, was a USRA design. A total of 97 railroads used USRA or USRA-derived locomotives. Steam locomotive types The USRA developed designs for 0-6-0 and 0-8-0 switchers, 2-6-6-2 and 2-8-8-2 Mallet locomotives, and both light and heavy versions of the 2-8-2, 2-10-2, 4-6-2, and 4-8-2 types.

USRA Light Mikado
The USRA Light Mikado was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. This was the standard light freight locomotive of the USRA types, and was of 2-8-2 wheel arrangement in the Whyte notation, or 1′D1′ in UIC classification. A total of 625 locomotives were built under the auspices of the USRA,Drury p.409 with a further 641 copies built after the end of the USRA's control. The first, for the Baltimore and Ohio Railroad, was completed in July 1918 and given #4500. The locomotives were considered well designed and modern, and were popular and successful. Large numbers remained in service until replaced by diesel locomotives. It was also called the McAdoo Mikado after William Gibbs McAdoo, head of the USRA. With later copies, over 50 railroads used the type, including the following: Copies: Preservation Nine USRA Light Mikad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mallet Locomotive
The Mallet locomotive is a type of articulated steam railway locomotive, invented by the Swiss engineer Anatole Mallet (1837–1919). The front of the locomotive articulated on a bogie. The compound steam system fed steam at boiler pressure to high-pressure cylinders driving the rear set of driving wheels (rigidly connected to the boiler). The exhaust steam from these cylinders was fed into a low-pressure receiver and was then sent to low-pressure cylinders that powered the driving wheels on the swiveling bogie towards the front of locomotive. Compounding Steam under pressure is converted into mechanical energy more efficiently if it is used in a compound engine; in such an engine steam from a boiler is used in high-pressure (HP) cylinders and then under reduced pressure in a second set of cylinders. The lower-pressure steam occupies a larger volume and the low-pressure (LP) cylinders are larger than the high-pressure cylinders. A third stage (triple expansion) may be empl ...

This was the standard light passenger locomotive of the USRA types with a 4-6-2 wheel arrangement in the Whyte notation, or 2′C1′ in UIC classification. History A total of 106 locomotives were built under USRA control; these were sent to the following railroads: After the dissolution of USRA, the ACL and L&N ordered additional copies of the USRA Light Pacific design, while both the Grand Trunk Western Railroad (GTW) and the Mobile and Ohio Railroad (M&O) also ordered copies in the 1920s...

USRA Heavy Santa Fe
The USRA Heavy Santa Fe was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. These locomotives were of 2-10-2 wheel arrangement in the Whyte notation, or 1′E1′ in UIC classification; this arrangement was commonly named "Santa Fe" in the United States. At the time, the Santa Fe was the largest non-articulated type in common use, primarily in slow drag freight duty in ore or coal service. A total of 175 of these locomotives were constructed under the auspices of the USRA. They went to the following railroads: The Pennsylvania Railroad locomotives were later refitted with the Pennsy's trademark Belpaire firebox The Belpaire firebox is a type of firebox used on steam locomotives.

USRA Heavy Mikado
The USRA Heavy Mikado was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration (USRA), the nationalized railroad system in the United States during World War I. These locomotives were of 2-8-2 wheel arrangement in the Whyte notation, or 1′D1′ in UIC classification. A total of 233 locomotives were built to this plan for the USRA; postwar, it became a ''de facto'' standard design, which was built to the total of 957 locomotives including the USRA originals and all subsequent copies.Huddleston (2002). Heavy Mikado used the same running gear as the USRA Light Mikado but were built to a higher axle load, larger cylinders and a much larger boiler for more power and steam-generating ability. Many aspects of the PRR L1s class were carried over to the Heavy Mikado, although not that locomotive's distinctive Belpaire firebox The Belpaire firebox is a type of firebox used on steam locomotives.

Russian Locomotive Class Ye
The Russian locomotive class Ye, and subclasses Yea, Yek, Yel, Yef, Yem, Yemv and Yes (Russian: Паровоз Е; Еа, Ек, Ел, Еф, Ем, Емв and Ес) were a series of 2-10-0 locomotives built by American builders for the Russian railways in World War I and again in World War II. They were lightweight engines with relatively low axle loadings. Due to the Bolshevik revolution in 1917, 200 locomotives were stranded in the United States; these were fitted with wider tires (locomotive driving wheels had steel tires which were heated to expand them, then driven over the wheels so that they shrank into place. By fitting wider tires with a deeper tread width, the effective wheel gauge could be decreased from the Russian standard of to , (the US standard) to fit the American gauge and were sent to various railroads. The locomotives were nicknamed "Russian Decapods." A number of locomotives were acquired by the Finnish railways (class Tr2) and by the China Railway (class DK2) ...

Axle Load
An axle or axletree is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle, with the wheels rotating around the axle. In the former case, bearings or bushings are provided at the mounting points where the axle is supported. In the latter case, a bearing or bushing sits inside a central hole in the wheel to allow the wheel or gear to rotate around the axle. Sometimes, especially on bicycles, the latter type axle is referred to as a ''spindle''. Terminology On cars and trucks, several senses of the word ''axle'' occur in casual usage, referring to the shaft itself, its housing, or simply any transverse pair of wheels. Strictly speaking, a shaft which rotates with the wheel, being either bolted or splined in fixed relation to it, is called an ''axle'' or ''axle shaft''. However, in looser usage, an entire assembly including the surrounding axle housing (typically a casting) is als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4-8-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels, eight powered and coupled driving wheels and two trailing wheels. This type of steam locomotive is commonly known as the Mountain type. Overview The Colony of Natal in South Africa and New Zealand were innovators of the Mountain wheel arrangement. The Natal Government Railways (NGR) placed in service the first tank engines with the 4-8-2 arrangement, and the NGR was also first to modify tender locomotives to use a 4-8-2 wheel arrangement. The New Zealand Railways Department (NZR) introduced the first tender locomotives designed and built as 4-8-2. In 1888, the Natal Government Railways placed the first five of its eventual one hundred Class D tank locomotives in service. The locomotive was designed by William Milne, the locomotive superintendent of the NGR from 1877 to 1896, and was built by Dübs & Company. This was the first known use of the whe ...
