At this time the railway ran in a circuit from the main station at Exmoor Central, trains descending on a large embankment before climbing back up through a spiral tunnel.
At the end of the 2001 season, the decision was taken to close the railway to the public and concentrate on building new steam locomotives and associated equipment.
By mid-2010 an additional 1⁄2 mile (0.80 km) of track had been brought into use, with a very steep ascending and descending ruling gradients of 1 in 28.
During the 1990s, a number of 1 ft 11+1⁄2 in (597 mm) gauge Beyer Garratt articulated locomotives from South Africa arrived on site and were displayed.
Over the winter 2008/9 work started on constructing around 1⁄2 mile (0.80 km) of 1 ft 11+1⁄2 in gauge railway to run the Garratts on.
