im planning on doing an HO scale train around my "man room" (aka, the basement) and am very new too all this, and basically still just thinking it all through. The problem I can see im going to have is I am going to have 3 large access doors to work around (2 of them are about 2 foot wide, and 1 about 4 foot wide. Ive been searching thru the threads in this forum and saw mention of detachable bridges and the like.. I was wondering where I might find more detail on this or possible solutions to my problem. I dont have any kind of drawings really, but the at the left corner, is the first 2' access door, and the next access door will be approximately 8' from that, and the big access door will be 2' past the second 2' access door. the 4' access door will actually be 2 2' doors. Hopefully I have provided enough info.
