The Dutch 'Efteling Stoomtrein Maatschappij' or properly translated 'Efteling Steam Train Company' is a 600mm narrow gauge railway passenger line in the theme park Efteling, the Netherlands.
The line was constructed in 1968 using Second-hand Cockerill rails in a U-shaped track around the park with a station at each end. Both stations had a wye or rail triangle enabling the locomotives to run chimney-first at all times. In 1984 the line was extended to a circular track. Nowadays there are three platforms along the line, at the Adventure and Fairy realms, plus one station for the fairy characters to board. Ride length: since 1984 3 km, covering the inner part of the park in a circle.
