These Bachmann models are loosely based on the Jackson & Sharp coach.
These passenger cars are 1:22.5 and look tiny next to a 1:20 locomotive.
Actually, they are models of tiny passenger cars.
I have a coach, an observation, and a combine.
The original was dark green with a red roof.
I had earlier decided on a cream and green color scheme for my railroad, but the dark green was the only thing available.
I was able to get some green clerestory windows from Bachmann Trains.
