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the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric or diesel-electric ...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

Its successors, both also of the 4-6-4T wheel arrangement, were the Dm class of 1945 that was rebuilt from older E class 4-6-2 tender locomotives, and the Dd class of 1946. The New South Wales Government Railways 30 Class 4-6-4T locomotives were used on Sydney and Newcastle suburban passenger train workings from 1903 until the end of steam ...
London and North Eastern Railway's (LNER) Peppercorn Class A1 is a class of 4-6-2 "Pacific" steam locomotives largely built between 1948 and 1949 at Doncaster and Darlington Works to a design of Arthur Peppercorn.
They were the first of the 4-6-2+2-6-4 type and were built by Hanomag in Germany. The locomotive specifications were prepared by Colonel F.R. Collins, Chief Mechanical Engineer of the SAR from 1922 to 1929, who designed it as a mixed traffic locomotive for use on branch lines and secondary mainlines throughout the country.
Baltimore and Ohio No. 5300, also known as President Washington, is the sole survivor of the P-7 class 4-6-2 "Pacific" type steam locomotives.It was built by Baldwin in 1927, and it was used on mainline passenger trains across the Baltimore and Ohio system, particularly the Royal Blue train, until it was retired in 1957.
