As I se that the "other scales" category hasn't seen a post in awhile, I'm throwing out my current project. I have a Stewart VO-1000 that looked like it could use a bigger sibling. It's been a year or so in fabrication, but I had it out on the tracks for over a week this month and it has performed perfectly. Well, with the exception of shearing off the bolts holding on the rear brake beam on a long 2% downgrade hauling a dozen cars... A few handrails and grab irons are on the workbench. Power comes from two large deep cycle batteries providing power to two 160 amp motor controllers and then out to eight electric motors (two per axle). I have it set up with both regenerative braking and straight air brakes. I will update the thread later when I complete the body and take some builder's photos.
