The Museum's narrow gauge railway, known as the East Suffolk Light Railway, opened in 1973. It was some long, running along the northern edge of the site, and the -gauge track was constructed from materials obtained from a sand quarry at Leziate, from Canvey Island and from the Southwold Railway. Signals were obtained from several locations in the vicinity. The museum also owns a van body which once ran on the Southwold Railway. In 2016, the museum acquired some land adjacent to the main site, and then applied to Waveney District Council to allow them to extend the museum site. The Council decided that such a move would be beneficial to the region, as the museum injected some £450,000 into the local economy in 2016, and voted to grant planning permission unanimously. The estimated cost for the development is one million pounds, which should see the tramway, the trolleybus route and the narrow gauge railway lengthened, and the total area of the site almost doubling. Plans include the construction of a new exhibition hall devoted to Eastern Coach Works, a major builder of bus and train bodywork, which was located in nearby Lowestoft, until its closure in 1987. The plans provided for two new depots to be built, one for trams and the other for trolleybuses. At the time of the application, some 20 vehicles were kept in store at Ellough near Beccles, and the museum aimed to move all of them to the Carlton Colville site, so that they could be seen by the public more easily. The first of the transport systems to be extended was the East Suffolk Light Railway, which originally terminated near the woodland tramway. Progress was blocked by a tramway siding, and one of the early jobs was to construct a flat crossing to allow the trains to pass over the tramway.
