Funny you should mention that BB. Ive known the guy who owns this for many years. Its called Fordland trains. I think he had 4 or 5 miles of hand laid track, its really quite spectacular. The engines and cars are accurate replicas, taking years to complete. He also machines parts for full size steam locomotives.

As a matter of fact, it would make a great stop on the scooter tour.
