Rides on steam trains are popular with tourists visiting the region, and that is why VSM operates mainly during the summer vacation.
In March 2011 one of the individuals who possessed a number of locomotives decided to sell his collection.
Each year, on the first full weekend of September, the "Back to Then" (Dutch: Terug naar Toen) event is held, using everything that will run.
The diesel engines are originally from the Dutch state railways, Nederlandse Spoorwegen (NS).
This way the VSM has a valuable collection of Dutch diesel engines dating from the fifties and sixties from the last century.
