Opting to build a series of modules depicting the branch line I always intended rolling stock to be able to move between them. The only issue was how to do it. I don’t have space for staging so I decided to build a fixture called a ‘cassette’ to store, assemble and move trains between modules. I first read about cassettes in one of Iain Rice’s books on small layouts and always thought that they were good way to save space and store trains. The underlying concept is of two aluminium corner bars mounted on a wooden deck which join to the layout at a docking point. The three main components are a cassette, a dock and a cradle. Here are some images of the design and construction process:
