Out of the box

Here we see how the layout folds in half to fit in the box file. The two boards are permanently hinged together at the back, and the hinge at the front has a removable pin to fix them together. The pin was removed by filing off one end, and is quite a tight fit.

The strip of maroon-coloured material visible in the box exists to facilitate easy removal of the layout, as there is not much clearance in the box.
