Richard Trevithick built the steam locomotive for his iron works at Penydarren. It was originally made of iron. Later on, John Blenkinsop invented a steam engine which had cogs on the wheels in 1811.

The diesel trains were invented by a German engineer, Rudolf Diesel, in 1892. The diesel fuel burned to “drive” a generator that made electricity that was stored in batteries below the locomotive. The electricity from the batteries power the motor and turns the wheels.
