Over the years I have built a few replacement drives for Bachmann’s Trolley. I started out using my Pittman motor which was too expensive for me and the customer. Later designed a trolley drive using a Bachmann Shay motor and cluster gear, with a Stock drive axle gear. I have decided to build the drill jig to build the chassis. I am guessing, but should be ready in about a month. Customers interested can get credit for their Trolley wheels and I will be interested in buying shay motors (still running) and the little black cluster gears.
