Well they used to run on steam power. Where wood or coal would be burned to make heat that would boil water and boiling water makes steam. When water turns to steam it expands and it can expand with enough power to move pistons. The pistons were usually connected directly to the drive wheels through long connecting rods that connected to the outer edge of the wheel.

Modern day train engines are usually diesel electric. Where a diesel engine is coupled to a electric generator and then the electricity from the electric generator is use to run electric motors which are connected to the drive wheels.
