I’m not certain the existence of a particular prototype in this case is all that important. Since pretty much all small industrial critters were unique, then maybe it makes more sense to pick various features from a catalog that typify what people tend to find appealing in narrow gauge. Given the popularity of the On30 version (and the myriad kitbashes thereof), I’m inclined to believe that even if there isn’t a specific prototype, it’s a darned good “average” of the varieties.
As for size, my rough estimate (Photoshop, using the height of the coupler and rail as references) puts the total height at around 5" tall to the peak of the cab, with the floor around 1 3/8" off the railhead. I’d guess the cab door is just about a scale 5’ 8" tall, thereabouts. Couple those dimensions with the roughly 4" x 8" width and length reported on 1:20.me, and you’ve got yourself a nice, small diesel that will become a medium diesel in 1:22.5. What better way to appeal to a nice, wide audience. Of course, if they merely scaled up the On30 version (which it looks like they did), then perhaps all we need do is enlarge that to 1:20.3 to see what we’re getting.
So far as the weight of the prototype goes, the D&RGW #50 is a 30 ton unit, and the EBT’s M-4 is 12 tons. The 10 ton units on the NERails look to have a lower cab, and also lack the weight of the counterweights and siderods of the B’mann loco. Adding those into the mix, and taking into account that the 2’ gauge loco on the NERails site is 18 tons, but looks to be a touch longer, I’d put the weight of this one between 15 and 18 tons. You wouldn’t want to move a lot with it, but it’d be good for 4 or 5 cars without much bother. As for brakes, etc., I’d imagine–like anything ordered from a catalog–they’re options.
Bottom line (for me, anyway), this loco has character regardless of whether it has a real prototype. I’m not a diesel/gas guy by any stretch of the imagination, but I’d be tempted by this one. It’s well proportioned, and I love the counterweights and siderods. (Am I really getting jazzed about something other than a steamer? I gotta change the water filter.)
As for the Bach-man’s comments, I interpret them as being sarcastic, nothing more. (Not that my mom ever said anything like that to me ) I wouldn’t read anything into them. I seriously doubt a company would trash thousands of dollars worth of tooling simply because someone let loose with a photo. They’ve just got to learn to time things better.
Later,
