Children's Railway Sakhalin, railway line in Russia

The Children's Railway Sakhalin is a 2 km narrow-gauge ring line running around Lake Verkhneye in Yuzhno-Sakhalinsk's Gagarin Park, with a full operating length of 2.2 km. It has two stops without passing loops, Komsomolskaya station and Pioner halt, and crosses the Rogatka river on two metal bridges with spans of 9 and 15 m. A 173 m concrete retaining wall, built in the mid-1970s, holds the embankment where the track runs along the lake shore.

In early 1953 the South Sakhalin railway administration proposed a children's line; from October 1953, 520 pupils of grades 5-9 studied railway trades. Railway troops under Colonel Tverdov built the track around Lake Verkhneye, and on 6 June 1954 the first blue train set off, driven by young railwaymen Vitaly Voronov and Viktor Maleev. In 1955 the direction of travel was reversed using a temporary turning triangle.

The 2 km ring line circles Lake Verkhneye in Gagarin Park, with two stops, Komsomolskaya and Pioner, and no points or sidings. At Komsomolskaya the track runs along the lake shore, where a 173 m concrete retaining wall built in the mid-1970s holds the embankment. The line has two metal bridges over the Rogatka River, with spans of 9 and 15 m, and steep gradients.

The opening train on 6 June 1954 was hauled by steam locomotive Uk-159-238, a class 159 engine with modified cab and running board, pulling three wooden two-axle carriages built in Germany in 1902. Young railwaymen Vitaly Voronov and Viktor Maleev drove it on the first run. The locomotive was withdrawn after the 1959 season.
