The introduction of the 4-6-2 design in 1901 has been described as "a veritable milestone in locomotive progress". [3] On many railways worldwide, Pacific steam locomotives provided the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric or diesel-electric ...

[4] [5] Although there were Ts and Ts-1 class 4-8-2 locomotives valid enough to that handle this work, they could not be relocated to some of SOU's routes over and over. [4] The SOU decided to revise the 4-6-2 type and ordered the more powerful Ps-4 Heavy Pacific class with the first batches built in 1923 by American Locomotive Company's (ALCO ...
Locomotives classified 4-6-2 under the Whyte notation of locomotive axle arrangements. The equivalent UIC classification of locomotive axle arrangements is 2C1 or 2'C1' . Contents
A locomotive that pulls a tender is called a tender locomotive. Locomotives that do not have tenders and carry all their fuel and water on board are called tank locomotives or tank engines . A corridor tender is a locomotive tender with a passageway to one side, allowing crew changes on the fly.
Southern Railway 1401 is a 4-6-2 steam locomotive built in July 1926 by American Locomotive Company (ALCO) of Richmond, Virginia, for the Southern Railway (SOU) as a member of the Ps-4 class, which was based on the United States Railroad Administration (USRA) Heavy Pacific design with some minor differences.
Thus a 4-6-2-type Garratt is a 4-6-2+2-6-4. For Garratt locomotives, the plus sign is used even when there are no intermediate unpowered wheels, e.g. the LMS Garratt 2-6-0+0-6-2. This is because the two engine units are more than just power bogies. They are complete engines, carrying fuel and water tanks.
The Karoo Class of the Cape Government Railways (CGR) was the first tender locomotive with a 4-6-2 Pacific type wheel arrangement to be introduced in Africa. It was the logical development of the CGR 6th Class 2-6-2 Prairie type which later became the Class 6Y on the South African Railways (SAR). [1] [2] H.M. Beatty
