The next locomotives to use the 4-4-4-4 arrangement were the Pennsylvania Railroad's 52 class T1 locomotives (although the single class S1 was originally intended to be a 4-4-4-4, it was later changed to 6-4-4-6 due to increased weight). These had the cylinders in front of the wheels they drove, so that the rear pair were between the two sets ...

The Canadian Pacific Railway built two classes of 4-4-4 "Jubilee" locomotives. Both were semi-streamlined, in a similar fashion to the 4-6-4 "Royal Hudson" and 2-10-4 "Selkirk" locomotives. The F2a was styled after the Milwaukee Road "Hiawatha" 4-4-2 "Atlantic", but with a four-wheel trailing truck to support a longer firebox.
Its high-speed capability was such that many have claimed that the S1 exceeded on multiple occasions the 126 mph (203 km/h) record steam locomotive speed set in 1938 by the British LNER locomotive 4468 Mallard. The engine was claimed to have exceeded 152 mph (245 km/h) on the Fort Wayne-Chicago run, as it was reported that the PRR received a ...
The Milwaukee Road Class "A" was a class of high-speed, streamlined 4-4-2 "Atlantic" type steam locomotives built by the American Locomotive Company (ALCO) from 1935 to 1937 to haul the Milwaukee Road's Hiawatha express passenger trains. Numbered from No. 1 to No. 4, they were among the last Atlantic type locomotives built in the United States ...
Class D16 on the Pennsylvania Railroad was their final development of the 4-4-0 "American" type of steam locomotive. [2] A total of 429 of these locomotives were built at the PRR's Juniata Shops, spread across five subclasses; some had 80 in (2,030 mm) diameter driving wheels for service in level territory, while others had 68 in (1,730 mm) drivers for mountainous terrain.
