Are trains electric or diesel powered?

Though trains are more efficient than trucks, not all trains are equally efficient. Diesel-powered trains transfer about 30-35 percent of the energy generated by combustion to the wheels, while supplying electricity directly from an overhead powerline transfers about 95 percent of the energy to the wheels.

Diesel trains are more versatile as they can work on the almost 60% of lines that aren't electrified and the portion that is. Diesel power can also transport exceptionally heavy loads and so is often used in the freight sector.

Railway electrification in Great Britain began in the late 19th century. A range of voltages has been used, employing both overhead lines and conductor rails. The two most common systems are 25 kV AC using overhead lines, and the 750 V DC third rail system used in Southeast England and on Merseyrail.

Besides steam- and diesel-powered locomotives, many trains operate solely on electrical power. They get the electricity from a third rail, or electrical line, along the track. Transformers transfer the voltage from the lines, and the electrical current drives the motors (AC or DC) on the wheels.

A train engine requires about a hundred litres of fuel to get it started. So it wouldn't be economical if the engine is stopped and started frequently. This apart, if the engine is stopped, the moving parts' lubrication will also come to a halt.

No, trains have no gears, since these are unfeasible. That's why their fuel (if any) is converted to electric energy and then used to run motors.
