I used an old corner module for the club I belong to to build a small Marx layout. The table is hexagonal, and measures roughly 5' x 3 1/2'. The track itself is an oval 27" x 54".

I use little house shaped cookie tins for the buildings. I can usually find one at the local Goodwill about every three months if I check pretty regular. I have more of them than will fit on the layout, so I rotate them occasionally.
Here's a few more shots of the layout, more or less complete:
