Coal Railway

The Kolenspoor was a tourist railway in Belgium between Waterschei and Eisden, on the route of part of the former railway line 21A and on the route of the former railway line 21B. Tourist trips were made on the line with old railway equipment.
Until a few years ago, the railway line was used as far as Eisden. Due to the poor condition of the track, this later became impossible. Since 2014, the tourist operation has been halted over the entire line and since 2015 the association "vzw Kolenspoor" has completely lost its concession on the Waterschei - As - Eisden section. The poor condition of the rails no longer allowed trains to run on the route.
