Diesel locomotive Dv12s. In the 21st century series production standard gauge diesel–hydraulic designs include the Voith Gravita, ordered by Deutsche Bahn, and the Vossloh G2000, G1206 and G1700 designs, all manufactured in Germany for freight use. Steam-diesel hybrid locomotives can use steam generated from a boiler or diesel to power a piston engine. The "Cristiani Compressed Steam System" used a diesel engine to power a compressor to drive and recirculate steam produced by a boiler; effectively using steam as the power transmission medium, with the diesel engine being the prime mover The diesel-pneumatic locomotive was of interest in the 1930s because it
Terra Nova 1260HP diesel hydraulic locomotive started to produce the Terra Nova locomotive, its future plans for 2015-2018 being to build a new 2500 HP diesel electric locomotive and a new 6500 kW electric locomotive. The Terra Nova locomotive is a 1260 horsepower machine powered by 2 x Cat C18 Engines of 630 HP each with Cat TR43 Locomotive Transmission packages being able to provide a tractive effort of 230 kN. Built for short-line (20–30 miles) railroad operations or shunting procedures, the Terra Nova is ideal for making line switches and organizing cars within a rail yard. Cat engines and transmissions are worldwide known for their
