Spent this weekend looking at the job and explaining about minimum radius curves, train lengths, point lengths and 4mm to the foot as a scale.
The 'mountains' are now to be 'a hill or two' and we are starting with the high level oval running round the walls (lift up section across doorway). This will have a station that is actually the fiddle yard (4 tracks inside the building), a smaller junction station diagonally opposite, where the branch to the industrial lower level joins the main line. That way we can get the circuit up and running, adding the industrial bit and the quay to the lower part later, this means he will not be leaning over delicate stuff on the front of the board whilst 'doing' the upper level.
It is all starting to look a lot more doable.
He's keen on using a shop (wants to see what he is buying) and is now looking at the Hornby Elite controller. For the moment I have retrieved some old OO stuff for him to play with to get a sense of scale.
He bought sopme 'large radius' curves, which give a 31 inch dia circle, which I would have thought was about as tight as they would go (apparently the chap in the shop told him there is an even tighter radius. Bit concerned as so many makes these days specify nothing less than 'second radius' - I wasn't there, not sure about this at all).
Woodwork starting this week.
