Steam Locomotives get thier power by burning coal in a firebox. This heats up the water which turns to steam. The steam drives a piston back and forth, this turns the wheels via connecting rods and cranks.
It takes about three hours for the crew to get up enough steam to get the locomotive moving.
The wagon where the coal and water is stored is called a Tender.. The tender is towed behind the locomotive. A tender holds 10 tonnes of coal and 30,000 litres of water.
Loco classes are described by their wheel layout. A 4-6-2 has four small leading “bogie” wheels, six big driving wheels and two small trailing wheels. These small trailing wheels carry a lot of the weight.
The first Loco to get to 100mph was the City Of Truro in 1895!
