A live steam locomotive is often an exact, hand-crafted scale model, and as the name suggests is steam powered.
Live steam locos range from Hornby's HO (not for the garden!) to the popular G Scale and G1 up to models big enough to carry people.
Live steam railroad scales are generally referred to by the number of inches of scale per foot. For example:
A 1:8 scale locomotive will often be referred to as a 1 1/2" scale locomotive.
Common modelling scales are Gauge 1 (1:32 scale), 1/2" (1:24 scale), 3/4" (1:16), 1" (1:12), 1 1/2" (1:8), 2 1/2" (~1:5) and 3" (1:4).
Track gauges can range from 2 1/2" up to 10" for rideable models.
