Map of the railway

The Zuid-Limburgse Stoomtrein Maatschappij (South Limburg Steam Train Company) or ZLSM is a heritage railway operating from its main station of Simpelveld to Schin op Geul and Kerkrade in the south of the Netherlands. It also runs across the border from Simpelveld to Aachen-Vetschau and has an extensive collection of stock. The ZLSM is currently[when?] partnered with the Great Central Railway in England, as they have both double-track railways, although one is disused[citation needed].
