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the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric or diesel-electric ...

William Dean, Armstrong's successor, designed (among others) four classes of locomotive, 2-4-0 and 0-6-0 tender and tank engines, which shared many standard components. However, it was Churchward who carried the policy to lengths which made GWR locomotives distinctive and shaped their development until the nationalisation of the railways .
They were originally built as 2-6-6-2s but were refitted with a four-wheel leading truck to increase stability at speed. Southern Pacific AM-2s were built from July to August 1911 by Baldwin Locomotive Works as Cab Forwards. These 4-6-6-2s began retirement in the mid- to late-1930s, although a few remained in operation until the end of World ...
L. B. Billinton was undecided whether to enlarge the J1 and J2 4-6-2 tank locomotives designed by his predecessor D. E. Marsh, or design an equivalent sized 4-6-0 tender locomotive. Large tank locomotives were well-suited to the railway's operating conditions, with a relatively short but very intensely used system, particularly in the vicinity ...
2-6-2+2-6-2 Under the Whyte notation for the classification of steam locomotives by wheel arrangement , a 4-6-2+2-6-4 is a Garratt or Union Garratt articulated locomotive using a pair of 4-6-2 engine units back to back, with the boiler and cab suspended between them.
The NZR A B class was a class of 4-6-2 Pacific tender steam locomotive that operated on New Zealand's national railway system for New Zealand Railways (NZR). Originally an improvement on the 1906 A class, 141 were built between 1915 and 1927 by NZR's Addington Workshops, A & G Price of Thames, New Zealand, and North British Locomotive Company, making the A B class the largest class of steam ...
Southern Railway 1401 is a 4-6-2 steam locomotive built in July 1926 by the 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.
