There is a track plan data base in here. On the black bar at the top, point to "How To", center column in the drop down.
It does have a search function, maybe you can start there.

I have an around the room layout,HO scale. unfortunatlly it dosen't have alot of operational potential. I would like to add a new section approx 2'x6'. it will be added to one of the long sides of the layout. That would make that section appox 4' wide. Part of that secton is accesible from both sides [doorway]. I would like to have a few small industries and a run around track. where might I find some track plans that I might be able to fit into that space? I'd be more than happy to buy a book if necessrary.
