The railway has a short demonstration line and an operational industrial diesel locomotive that provides cab rides to visitors.

The quarries, however, suffered a boom and bust existence and their business dried up by the 1950s[2][3] leading to the line's final closure on 20 October 1958.

In 2012 the group gained planning permission to build a visitors centre near to the site of the former Fimber and Sledmere station.

It was originally operated by British Steel Corporation at Shotton, and later by Trackwork Ltd of Doncaster as a training vehicle in the rail engineering unit at HM Prison Lindholme.

[14][15] Planning consent was granted on 17 May 2012 for the laying of 0.9 miles (72 chains) of track from Fimber Halt to the edge of a field.
