The Superbowl Drive

I had not been very happy with the drive that I was able to put together based on a Tyco GP-20 drive that I had been using on my Orient decorated Kemtron GP-7. This engine was available set up from the factory for either a Baker drive (with a belt drive) or the Kemtron-Lindsay drive (with the motor down in the power truck). My engine was set up for the Lindsay drive, and it came to me with one that was incomplete. It looked great and ran with the Tyco drive I installed, but not very well.

Fast forward to just a couple weeks ago. I was able to acquire a Schorr RS-2, which I mentioned in this post. It is in rough shape and had a drive on it that had been worked up from a Kemtron-Lindsay drive like my GP-7 needed. As I plan to repower that locomotive with Athearn drive parts there was an opportunity to shuffle some parts around. Doing the majority of the work during the Superbowl I was able to disassemble and rebuild that drive and mount it on the engine which now runs much better and it is also a good bit more powerful. And it still looks great.

It was not a simple job as it involved replacing the axles which were damaged. Fortunately, I had spare wheelsets that I found a few years back installed in if I recall correctly a S-C passenger truck. Save everything!

Thus, the photo is a bottom view of this type of drive, set up and completely operational with vintage Hobbytown universals. The truck sideframes are suspended and hang from the ends of the wheelsets with the bracket on the bottom. Click on the photo for a closer view.

I actually have another GP-7 that I have not been able to operate. It has the Baker drive and was purchased from Pierre Bourassa, featured in the post below. That engine will be going through the shop soon, I now have a replacement universal for it I can salvage from another drive and I think have everything I need to get it running given a few hours to work it over, a project for another weekend. When it is running I will post a photo of that engine as well.
