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,
TU2 diesel locomotive trains. Later they were replaced by more modern designs. As of 2007, they are no longer in use on the narrow gauge railways in Russia, but some narrow gauge railways in Ukraine still use them. Many children's railways use TU2 locomotives too. The Aukštaitijos narrow gauge railway in Lithuania also still operates the TU2. TU2 is a diesel-electric locomotive. The main diesel engine is 1D12 and it produces 300 hp. The main engine drives the electric generator (195 kW) that supplies electricity to four traction motors, 62 kW each. TU2 diesel locomotive TU2 (ТУ2) is a Soviet narrow gauge diesel
