Search millions of objects in the collections including photographs, artworks, artifacts, scientific specimens, manuscripts, sound records, and transcripts. In the post-1968s, the factory began to manufacture diesel-hydraulic locomotives. Diesel-hydraulic locomotives use one or more torque converters, in combination with fixed ratio gears. Our B and BB diesel-hydraulic shunters offer great start tractive effort and very smooth engine to wheels torque transmission. Only three were built, all for Southern Pacific Railroad in 1964 (#9018-#9020). Built for the Southern Pacific the model was similar to UP's massive C855 design in that it was essentially two locomotives merged into one. How does a diesel-hydraulic locomotive work? Therefore, a. design work on the 'Western' locomotives, Swindon turned to creating a cheap 'no-frills' Type 1. Hydraulic transmission works on the same principal as the fluid coupling but it allows a wider range of "slip" between the engine and wheels.
