Garden railway

Model locomotives in this scale are often live steam scale models of British narrow gauge prototypes.

16 mm scale (which runs on 32 mm / 1.26 in) track, the same gauge as O gauge is probably now more popular in the UK than G scale.

1/32 scale (1:32) is also called "three-eighths scale" meaning 3/8 of an inch on the model represents one foot on the real thing.

They are smaller than the Backyard railroad, or what is commonly called a miniature railway, and would not provide a ride-on facility, being intended instead as a display railway.

Smaller scales and gauges are used in the garden, but in general garden railway is used to refer to the medium scale sizes which would be impractical to use indoors.
