Narrow-gauge railways in Russia

The Imperial Russian narrow railway track gauge was 3 ft 6 in (1,067 mm), the current track gauge is predominantly 750 mm (2 ft 5+1⁄2 in).

In Soviet Russia, narrow-gauge railways were mostly common in forestry and peat industries in low inhabited places.

Usually they have one main line and number of temporary branches.

There was commonly a passenger service to villages and towns for workers.

Also children's railways are located in many big cities.
