Gauge 2 (also called 2 gauge or II gauge) is a model railway
Railway modelling (UK, Australia, New Zealand, and Ireland) or model railroading (US and Canada) is a hobby in which rail transport systems are modelled at a reduced scale.
The scale models include locomotives, rolling stock, streetcars, t ...
