[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the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric or diesel-electric ...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 ...
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 Class S 3/6 steam locomotives of the Royal Bavarian State Railways (later Class 18.4-5 of the Deutsche Reichsbahn) were express train locomotives with a 4-6-2 Pacific (Whyte notation) or 2'C1' (UIC classification) wheel arrangement.
Swiss classification: 3/5+3/4. This wheel arrangement was used only as a very limited number of locomotives in North America, most notably as class MM-2 oil-fired cab forward locomotives on the Southern Pacific Railroad. [1] These were effectively 2-6-6-4s running in reverse.
