The museum was founded starting with a former standard gauge railway carriage which today acts as a licensed buffet and restaurant car.

Other attractions include a 7+1⁄4 in (184 mm) gauge miniature steam railway which runs for 1-mile (1.6 km) on the site.

The railway is a single track running around the perimeter of the site.

There is also a one-third full-size (1:3) electric tramcar which runs for a 0.5-mile (805 m) on the site, on track of 15 in (381 mm) gauge.

This is one of only two electric tramways in Wales (the other being a short 18 in (457 mm) gauge electric tramway in Heath Park, Cardiff, owned by Cardiff Model Engineering Society).
