This is a massive diorama project executed in 1/35 scale by a single individual. It is comparable to a large model railroad project but without the trains. I have ordered his books, but they haven't arrived yet. His web site gives a pretty good idea of the scope and detail of the project. It is worth a look.
Before I started the 1/48th scale ACW RR project, I seriously considered building my ACW RR in 1/32nd scale. It would have been to Gauge 1 standards.
To get started I had a copy of the Andreas Models General locomotive. It was a highly detailed static model of the engine. I also started to collect 1/32 wheel sets and other items. This effort was cut short when Dave at SMR trains introduced his line of locomotives. So I sold the 1/32nd locomotive model to a fellow in Brazil via ebay.
I do miss the beautiful 1/32nd scale figures that are available in that scale. Can you imagine the Potomac Creek bridge in Gauge 1!
Did I make the right decision?
