Track finally arrived so building can commence.
The layout is as below, top run 20ft, left edge 13ft of which 7ft in the middle will be a 3 span bridge and bottom run 16ft.
There are 24 MTB1 motors for points and 3 DR4018's to run them, a bus running the length with droppers hmm that will surely be another set of questions for later.....
There will be c20 engines on the layout with max 4 running any given time.
The system is z21 with multimaus handset and phone/tablet for further controllers.
So the big question is will I need a booster as I have no idea and if so where to place it.
