Narrow gauge railway
Narrow-gauge railways occupy a special place among railway fans and today are an endangered form of transport. They differ from conventional railways by a smaller gauge, but at the same time they are a full-fledged railway with their own rolling stock and infrastructure. The first railways in Russia appeared in tsarist times, but their heyday fell on the Soviet Union. Narrow-gauge railways are lighter in weight than conventional railways, they are easier and cheaper to build, so they were actively used to export peat, forest, sand, and transport passengers to remote sparsely populated villages. Over time, it became unprofitable to maintain and maintain such roads and most narrow-gauge railways ceased to exist. They remained in remote corners of the country, as well as in the form of children's railways, private "country" narrow-gauge railways, lines at various museums.
