Gary: This HO Scale? You don't show the room the layout is in...so if you can get around it on all sides, good. If not, you could have problems at the bottom right, and both top corners. If those are 1' major squares you are looking at ~36" for reach in.
Why is the building bottom left so far away from the bottom edge? Move it down and gain some room. What are those 3 buildings on the right side? To me, the TT placement is iffy. Move it closer to what looks like a yard and provide entry for it from there. If it is a 'yard' need some sort of escape track for power coming in.
