I’m retired and interested in building an N gauge layout.  I have built a 4’ X 8’ table.  I am stumped at finding a detailed track plan.  I’d like to be able to run three trains on the layout. Planning on a mountain/tunnel, and town.  But, I can’t get started without knowing exactly what track and switches to order. I would be happy to pay for this plan. NIm live in Brookline Masssachusetts.
