Thanks, some really interesting ideas here. I'm sure there were no cassettes around when it was first drawn. I'll have to do some measuring up and see what the possibilities might be. I'm looking at a total max available length of about 17 feet, with 10 feet set aside for the scenic part, which will allow for an occasional six coach train but mainly 5 coach suburban with tank engines/small tender engines, with an available engine in the spur to take the coaches out as the next train. (As described by CJF). I'm not keen on three way points, got one on the current BLT and vowed never to use one again. Most of the time it works ok with most of the stock, but even with a lot of tweaking I'm not really confident in it which is a great shame as it's a great space saver.
