Diesel locomotive Diesel–hydraulic locomotives have a smaller market share than those with diesel electric transmission - the main worldwide user of main-line hydraulic transmissions was the Federal Republic of Germany, with designs including the 1950s DB class V 200, and the 1960 and 1970s DB Class V 160 family. British Rail introduced a number of diesel hydraulic designs during it 1955 Modernisation Plan, initially license built versions of German designs (see ). In Spain RENFE used high power to weight ratio twin engined German designs to haul high speed trains from the 1960s to 1990s. (see RENFE Classes 340, 350, 352, 353,
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
