I have twin 5yr old boys who looovvvee trains. So I took them down to a Model Railroad convention that was in town this weekend just so they could see some cool layouts. We went on a tour that included a big layout downtown, and some others. The boys of course loved every minute of it. At one of the tour stops there was a box marked 'HO Train Stuff... Make Offer for it all'. So I said to one of the model RR guys... how bout $25 bucks?" Next thing I know... I'm building a rain table in one of the bonus room dormers. I think this could get dangerous. My wife already gave me that 'you better stay off eBay' look. The boys told me now I need to make some mountains... and a tunnel and a lake and an army base.... and and and... I think I need to add a bank with a tiny ATM machine. NEWBIE ALERT!!! Anyone have any layout ideas that would work with this space? I'd like to have two trains running. Need to utilize a bridge and a mountain for sure. Definately will want some elevation changes. Left side is 7' long and 3' wide. The back side by the window is 7' long and 4' wide. I think I'll need to use that 15" radius turn rails that I've read about. Thanks in advance for any replies! e.
