Founded in 1963, the National Railway Museum collects their large static collection in two pavilions and the historical goods shed at the site of the original Port Dock railway station.

The museum operates a number of historic locomotives for shunting purposes and special events where large passenger numbers are applicable, in lieu of this, the 18" gauge steam locomotives and a diesel operate rides of 1.2 km around the museum. In 1992, the museum, in co-operation with the local council, built a 2 km line along the beach from Semaphore to Fort Glanville. This is operated from October to April, weekends, public holidays and school holidays when temperatures are below 35 degrees celsius. The line travels along the coastline, through the sand dunes and the Fort Glanville Conservation Park, with the engine being turned and run around at each end of the line, which is a delight for tourists who enjoy the beachside trip.
