Steam trains were once widespread, and changed the world. A steam engine is an external combustion engine, meaning that the fuel burns outside the engine. In modern internal combustion engines the petrol or diesel burns inside the engine, and the gases produced expand and push the cylinders, and this motion eventually turns the wheels. In the steam engine the fuel burns in an external fire box. The heat boils the water to make steam, which pushes the cylinders. So it depends exactly what you mean by 'run'. Certainly there were and are steam trains, but the steam doesn't provide the energy to make it go, the fuel does.

Steam can be used to transfer power, but it can't be used for fuel.
