In need of reliable medium-horsepower six-axle road switchers, Union Pacific’s Mike Iden turned to Progress Rail’s EMD subsidiary to rebuild a batch of out-of-service EMD 3,800-hp SD60s into more modern 3,150-hp units with new prime movers for secondary road freights. Twenty-eight — Nos. 9900 to 9927 — were built in the late 2000s. Progress later […]

Black and white photo of Akron, Canton & Youngstown H20-44 No. 503 crossing over a double track main line

The Fairbanks-Morse H20-44 was another mid-century diesel that didn’t.     FM’s first foray into the diesel road-switcher market was unconventional, to say the least. In 1947, instead of following the already traditional convention of a cab surrounded by a long and short hood, the Beloit, Wis., builder introduced the H20-44, and it looked like […]

Ultimate dual-service engine: New York Central 4-8-2 Mohawks

Example of New York Central 4-8-2 Mohawks on freight train by station

The New York Central 4-8-2 Mohawks were the ultimate dual-service steam locomotives. For some railroads in the steam era, it wasn’t enough to have success with a single example of a standard wheel arrangement. Instead, new competitive challenges and evolving technology often caused railroads to rethink a given locomotive class and turn it almost entirely […]
