Diesel locomotive set, and went into series production with other streamlined car sets in Germany starting in 1935. In the USA, diesel-electric propulsion was brought to high speed mainline passenger service in late 1934, largely through the research and development efforts of General Motors from 1930–34 and advances in lightweight carbody design by the Budd Company. The economic recovery from the Second World War saw the widespread adoption of diesel locomotives in many countries. They offered greater flexibility and performance than steam locomotives, as well as substantially lower operating and maintenance costs. Diesel–hydraulic transmissions were intrdouced in the 1950s, but from the
TU10 diesel locomotive TU10 diesel locomotive The locomotives TU10 (Russian TУ10) of the Russian Railways (RŽD) are narrow gauge diesel locomotives for children's railways. The children's railways or pioneer railways were used for extracurricular education, where adolescents learned railway professions. This phenomenon originated in the USSR and was greatly developed in Soviet times. However, existing children's railways continued to be used, and new tracks and locomotives were built even after the break-down of the Soviet Union. Most of these railways operate diesel engines, but some of them occasionally fire up old steam locomotives. Some TU2 diesel locomotives from the 1950s are still being
