Disel is used by train.
Usually electricity.
Lots, because a train is heavy. A 500 gallon fuel tank is small. BUT ... the amount of fuel used to move a ton of freight is roughly one quarter what it takes to move it by truck (and a tenth of what it takes to fly it).
Nope - a train is a mechanical device.
The modern train runs on diesel fuel.
They don't actually have fuel, they have magnets. The track has powered electromagnets in it. The electromagnets make the train "hover" and propel it.
A train typically converts electrical energy from overhead wires or fuel energy from diesel engines into mechanical energy to power its wheels and move forward. The mechanical energy is then used to overcome friction and propel the train along the tracks.
The fuel tank on a locomotive is under the locomotive body, between the trucks.
Coal or wood
The key findings from the electromagnetic train experiment show that magnetic fields can be used to propel a train forward without the need for traditional engines or fuel. This demonstrates the potential for more efficient and environmentally friendly transportation systems in the future.
To move the same weight the same distance by train uses less energy/fuel than if moving it with a bus.
Coal was burnt in the furnace. This heated water in the boiler to high temperatures. The steam was used to operate the pistons and to drive the train.
The only time a train has been powered by fish during coal shortage in Turkestan in 1919. Dried fish caught in the Aral sea were use as fuel . A total of almost 9000 tonnes were used to stoke the train's boiler.
