So I went to the SAMRA hobby show in northern San Antonio this weekend. When I attended last year, I was modeling HO and didn't pay much attention to the On30 modules, but this time most of the hour or so I spent there (the show is miniscule compared to my favorite one at the Eastern States Exposition) was inside the small room where On30 was housed. I have to say, I was stunned by the dissimilarities between the sizes of the different Bachmann engines. I realize that each model was based off of a different prototype owned by different railroads (and which ran on different gauged track?), but it seemed like you could almost group the 2-6-0, 4-6-0, 2-8-0, 2-4-4 and the shay into one group, and the 4-4-0 and 2-6-6-2 into another. The 4-4-0 was puny - and by that I mean that it could almost have passed for a large HO engine- and the same thing goes for the 2-6-6-2, which might have been two inches longer than the 2-8-0, and appeared to be at least an inch shorter in height. The cab heights were the biggest issue for me - while I could accept that the boiler and frame length on the 4-4-0 and 2-6-6-2 might be small by comparison, the cab sizes almost looked like they were a different scale from On30 - and it's not like the 2-8-0's cab isn't already cramped for 0-scale figures. It isn't that I don't appreciate the 4-4-0 and the 2-6-6-2 (and perhaps if the price ever goes down on the 4-4-0 [$200 for that little thing? That's more than twice as much as a 2-8-0] I might get one), but this size thing certainly made me do a double take. I'm concerned its exagerated to such a degree that the engines in the two groups actually look wrong next to each other. Has anyone else noticed this?
