Building a liftup

Thats cool mtrails! How wide is the lift up section?

Off the wall idea (no pun intended)....
The lift up section in the photos looks like it shows a threshhold. I have seen that other places. That got me thinking:

How about having the bridge be a rigid length, and have it drop into pockets? The pockets could pull the layout towards the bridge end. This would avoid the humidity issue. I think this would work if one end that the bridge connected wasn't rigidly fastened to a wall, so it have a little give.

BNRAILROAD - The lift up "module" is 48"x30". The disconnecting section itself is 24" long, 30" wide. It's basically self adjusting in all respects, including humidity changes. If environmental changes cause a severe enough tolerance change. it can be easily adjusted by loosening a couple of nuts, and making the minor adjustment.

In hindsight, I probably could have located the all-thread that serves as the hinge point at the subroadbed level, and would have separated the tracks without a bind. Oh well, good thing scenery will help cover it up!

That's cool! Still in the planning stages on my railroad. I have about 20 some ideas. It's one of those odd things. My present pike has been in exsistence for about 50 years (a long time!). It is basically 4 interchangable loops. This means I can run 4 trains at once. I love that feature! The issue is keeping the feature and adding operation to it. This has been the biggest hang up. The second having enough room for the operators and guests. The whole thing has to fit in a 11 1/2' x 13 1/2' room in HO. I wish at this point I would have gone N gauge!!!

Oh well!
