Hello to all, I'm a newbee, I'm modeling N scale present day Philadelphia to Reading line in an around the room shelf layout. my focus is CP Rail, with a smattering of NS, CSX, and Reading and Blue Mountain Northern. As a shelf layout it is 12" wide at its widest point and 11' x12' layout, although one 12' wall is only a 3" wide shelf (had to fit it above a couch, guest room set-up!) but I have included a planned tunnel (Phenixville) and the viaduct bridge across the schuykill river on that side. I've taken some modeler's license because I wanted to include some of the Philadelphia high line and the port of Philadelphia. It is still very much a work in progress, but I am already running trains (DCC) and have a smooth operation. I'll post pictures when I get a chance I'd like to get some more done first! Here are my 2 questions: 1) Can anyone point me to a plan for the Reading Spring street yard plan? I am planning on putting together a modular removable Reading on the "closet & door" end of the layout and I would like to include the very active Spring street yard. 2) as this end of the layout will be detachable, I could really use some recommendations on how to attach the modules to the permanant layout. On one side it will attach at a right angle to the layout, on a curve, on the other side it will attach straight to a 3" wide section. thanks, this group has been inspirational, wish I had more room, south Florida houses are small!
