This morning after a bit of a fossick through the book shelves ( I must find some bindings for my collection of Railfans) I came across my collection of information for the Rimutaka incline.
No sign of a doodle for a complete layout (I'm sure that I did one) but there was a plan for Cross Creek.
The top plan was a test sketch, obviously I thought that the extra passing loop could be done away with. Not sure why I included a second crossover as this was in the days before I made my own track. on closer inspection I've brawn over the top and so I think that the intended orientation is as shown in the first plan. There's also no notes on size and I'm guessing that it would probably fit on 8' if some compromises on train length were to be accepted. depth would ideally be 2'6"to 3' to model the hill behind to get a sense of dwarfing the station.
