Rethinking Famoco 6-wheel trucks

Back in 2015 I had a closer look article on Famoco 6-wheel passenger trucks. They are of a different design than S-C trucks, and at that time I had two things using them on a specific car accomplished: it freed up a pair of S-C trucks to use on another car, and I thought the look was nice on an ATSF baggage car.

This past week I had that car out again and was wanting to run it, and noted that it was shorting out. With this closer look article, I'll add this: these are not a great truck design. Even with a fresh truck, with good wheels, as things flex as the car rolls around the layout the insulated wheels short out against the sideframes.

The photo provides an even closer look. As I noted before, the bolster is integral to the design and is held on with the pin and locking washer, as seen on the right.

Back in 2015 I also had more of a passenger truck shortage. Now, with the 3D printed bolsters available (more here! I love these) and having used many of them to get a lot of trucks in shape, I'll be converting that car back to S-C trucks and reliable operation.
