Ten of these U-108b Class locomotives were built by the Baldwin Locomotive Works for the Union Railroad in 1936, the only 0-10-2s built new for a US railroad. They were consequently dubbed “Union” type locomotives. The 0-10-2 arrangement resulted from the relatively short Union turntables, the need for high adhesive weight and power and the relatively short runs(Submitted on February 1, 2022, by Cosmos Mariner of Cape Canaveral, Florida.)at low speed, which allowed for dispensing with a lead truck. #604 is the only survivor. It was donated to the City of Greenville, PA, in 1985 and is on display at the Greenville Railroad Museum Park on Main St.Photographed By Cosmos Mariner, June 15, 20212.
