What kind of fuel do regular trains use nowadays
Ordinary trains use diesel fuel, also known as internal combustion locomotives.
The vast majority of internal combustion engines used on our railroads are diesel engines. Fuel is burned in the cylinder, the thermal energy is converted into mechanical energy output by the diesel crankshaft, but not used to drive the wheels directly, but through the transmission device is converted into suitable for the requirements of the locomotive traction characteristics of the mechanical energy, and then through the walking part of the locomotive driving the dynamic wheels rotating on the track.
In China, the concept of internal combustion locomotives customarily refers to diesel locomotives. Internal combustion locomotives in the internal combustion engine and the moving wheels between the addition of a transmission device and the engine is equally important and in line with the traction characteristics. There are three types of transmissions: mechanical, hydraulic and electric. The internal combustion locomotive equipped with electric power transmission is called electric power transmission internal combustion locomotive.

The History of Trains
The world's first real steam train on rails was designed by Cornwall's engineer Charles? Trevithick, which had a train with four power wheels and was tested on February 22, 1840.In 1879, the German Siemens Electric Company developed the first electric locomotive, which weighed about 954 kilograms and made only one performance at a Berlin trade fair.
October 27, 1903, Siemens and General Electric developed the first practical electric locomotive into use. It reached a speed of 200 kilometers per hour.
Oil locomotive: In 1894, Germany successfully developed the first gasoline internal combustion locomotive. 1924, Germany, the United States, France and other countries successfully developed diesel internal combustion locomotives, and widely used in the world. 1941, Switzerland successfully developed a new type of fuel oil turbine locomotives, diesel fuel, and the structure is simple, small vibration, good operating performance, commonly used in industrial countries.
Since the 1960s, countries are vigorously developing high-speed trains, such as France, Paris to Lyon high-speed trains, the speed of 260 kilometers per hour; Japan's high-speed trains from Tokyo to Osaka, which also reached more than 200 kilometers. People are still not satisfied with such high-speed trains. France, Japan and other countries took the lead in the development of the magnetic levitation train.
China also built the world's first commercial maglev train line in Shanghai, from the metro Longyang Road station to the Pudong airport, this train is suspended above the track, the speed of up to 400-500 kilometers per hour.
