What type of coal do they use in trains?
Steam coal.
Coal is still used in many steam engines today. Coal is not used on diesel trains or electric trains simply because it is not fuel for them. Electric trains and diesel trains are the most common trains in use, and not trains capable of using coal, because they are more efficent and much less costly to maintain.

Welsh coal is supposedly the best quality. It was used by British rail in their steam trains. Welsh coal burns hotter.
Only (some) steam engines used coal. It was burnt in a boiler to heat water to steam.
coal be useful in many ways especially for powering electricity
most of the time, it also depends on the type of train Coal is used in steam locomotives! The coal is burned under a "boiler" to create steam which is then used in drive pistons which in turn cause the "drive wheels" to turn, thus propelling the locomotive, and the attached cars, down the track.
Trains earlier ran on coal. Coal was responsible for ozone depletion.
