The railway viaduct dominates the villagescape of Sint-Martens-Voeren. The viaduct spans the Voer Valley and is part of the railway connection Antwerp-Tongres-Aachen. The railway line was built in the First World War. Two kilometres further on, at the hamlet of Veurs, the railway line enters a tunnel that, at 2130 metres, is the longest in Belgium. Since 1958, only goods trains have used the line. In Remersdaal, the railway viaduct also occupies an important place in the landscape.
