We don't have the room at GEMTS to elevate track to the level required for
your arch bridge, not without dedicating a full *two thirds* of our space to
elevating the track, and consiquently obscuring at least 1/2 of our layout
behind elevation.

OK. John, you're our next stop on the "heaps of technic" train, would you
be willing to tackle a short (30" or less) trestle bridge, possible a double
track bridge?
I am also hesitant to make a double-wide arch bridge spanning

Ok. This means we need to make 2 more table sets instead of 1 this summer,
but does give us that extra room for buildings & stuff.

The only problems I see with this are that 1) the roundhouse is in the wrong
place - it is in the middle of a 30x60 table, not the end, so the rail yard
would have to get shuffled around and 2) there's virtually no room for
buildings and town stuff. You need at least 2 baseplates wide to have
buildings and a street.
