Put into service in 1902, this railway linked the Petite Espinette in the Brussels municipality of Uccle (at the limit of Rhode-Saint-Genèse), then served by the old line to Waterloo of the Brussels tram, to Boitsfort railway station, on the Brussels–Namur–Luxembourg railway line.

Established in the Sonian Forest, the line was 2.5 kilometres (1.6 mi) long.

After the First World War, it was abandoned for reasons of unprofitability.

Having served as a shed for the rolling stock, it is the only remnant of the old railway.

In the 2010s, this building served as a storage facility and shelter for foresters.
