Debate is still happening about how to attach the ends so they can be easily attached / detached. With Cliddesden we used 2 bolts on each side, but they were a bit fiddly when we had to construct it at a model railway show 1 hour before it opened. So, we are thinking about using hinges, unless anyone can think of a better idea.
You may have noticed from the picture, that there is a slit at the back of the board, this is so we can drop in a 4mm hardboard back scene depicting the rest of the Thornycroft site. Making that is going to be a challenge in itself due to perspective and buildings being part model and part back scene, and trains running through it - I'm sure we'll work it out. We have also marked roughly where the track will be laid.
