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the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric or diesel-electric ...

The Pennsylvania Railroad K4 was a class of 425 4-6-2 steam locomotives built between 1914 and 1928 for the Pennsylvania Railroad (PRR), where they served as the primary mainline passenger steam locomotives on the entire PRR system until late 1957. Attempts were made to replace the K4s, including the K5 and the T1 duplex locomotive.
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.
LNER Class A4 4468 Mallard is a 4-6-2 ("Pacific") steam locomotive built in 1938 for operation on the London and North Eastern Railway (LNER) at Doncaster Works to a design of Nigel Gresley. Its streamlined , wind tunnel tested [ 1 ] design allowed it to haul long distance express passenger services at high speeds.
[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 ...
The F-19s, Nos. 490-494, were the final new 4-6-2s the C&O received (later 4-6-2s would be purchased second-hand from the Richmond, Fredericksburg and Potomac Railroad (RF&P). No. 490 was the first locomotive of the class, and it was initially assigned to pull mainline trains on flat portions of the C&O system east of Charlottesville, Virginia ...
The Southern Railway numbers followed an adaptation of the UIC classification system of using letters and numbers to designate the powered and unpowered axles, together with a running number. Thus the first 4-6-2 locomotive became 21C1 – where "2" and "1" refer to the number of unpowered leading and trailing axles respectively, and "C" refers ...
