With all the interest in this Bachmann loco, I feel it will be similar to the LGB Mogul and will act as the second landmark loco for getting a lot of people into G scale, specifically 1:20.3 this time.
I got into large scale early on, and as a result have amassed a large collection of LGB sized (1:22.5) equipment. So while I'd love to have a K-27 for our layout, 1:20.3 is just too big. And my hopes of an LGB scaled version are now essentially destroyed with Bachmann's K-27
Take a look at the link in my signature to see photos of our 1:22.5 scale D&RGW themed layout.
