Building a modular home layout

[lajry]

Shown below is what Dennis Ivison used to build his O scale narrow gauge South Pacific Coast layout & show module in Garden Grove CA. His layout was on the 42nd Model Railroads of Southern California layout tour last September. Wish I'd seen this before building mine but any future ones will be built this way. Dennis got most of his Styrofoam free. He happen to see some being thrown away at a construction site. He asked if he could have & they said yes. This is a very good way to build K.I.S.S. modules!
