Fold down 4x7 layout build

Giving my new layout its own build thread.  Size is 4x7 as 8 foot made it hard to get to the latches that lock the layout in the closed position.   The frame on the wall is 1x10 pine bolted with L brackets to the studs.  The table portion is 1x4 pine with a thin plywood top with drop down 2x2 legs that drop out as you ,lower the layout down.   I based this design on my best friends layout his dad built that folded down over his bed.  Only change was from 2x10 wall frame and 2x4 table frame as its not going to have a pair of kids climbing on top while playing trains.(it was all the two of us could do to lower it down as 10yr olds, it was **** heavy back then).   I can fold this down by myself.   The underside will be enclosed once wiring is done so that it looks nice when closed.   I added the grass mat today and my track should be here soon.   I plan to do a double level with prewar OO on top and my 1946 Berkshire set on the lower loop. A Lionel Type R will power the trains and a small Lionel transformer will handle lights and so forth.   Here are a couple progress pics.  My nice bridge I got from one of the Trainworxx flash sales is sitting on the layout.   AD
