I currently have a peribiliary n-scale track on a door. I am planning to expand with T-track modules. I have an interest in: T-Track N-scale DCC Arduino Running operations and switching Would like to do 3d printing but have limited room I have limited space 10x12 room to share as my computer room. I am thinking of a multi deck layout but building the benchwork is not something I am comfortable with. I have a few old engines thinking of dcc conversions.
