The track consists of 3.5 in (89 mm), 5 in (127 mm) and 7.25 in (184 mm) gauges. The majority of passenger hauling is done by 7.25 inch gauge locomotives. However, smaller locomotives do often run successfully. The club owns several locomotives : * 7.25 inch gauge 'Sandwell Lady'. A narrow gauge Hunslet type locomotive built by the members of the society. * 7.25inch gauge Black 5, number 5241, built by a local engineer and donated to the society. * 7.25-inch gauge "Nigel", a Hercules class locomotive * 7.25 inch gauge "Nefyn", a narrow gauge Reemus class locomotive. * 7.25 inch gauge petrol hydraulic locomotive. The track runs round the gardens of the transport museum and includes locomotive sheds, a station, a tunnel and a viaduct. The steepest climb on the line stretches from the viaduct to the tunnel with a 1 in 110 climb. The trip consists of two loops passing the station twice via a loop line.
