Now THIS is a model railroad
I used to work with the guy that owns this property.
It's 7 1/2 inch gauge.
Pretty hardcore. Lots of hand tooled parts.
There's a boxcab kit than runs on a deep cycle battery that probably the cheapest powered unit available at around 3-400 bucks.
They have an open show and swap meet every year.
Talk about an expensive hobby!
