Legacy SD45. So far it’s not complaining:
This came with factory “kinematic” pilots and Kadee mounting pads. Though I planned to fix the pilot all along I installed Kadees using the mounts just to see what happened. The engine operated normally except the Kinematic pilots swiveled in curves and it sounded as if the wheel flanges were rubbing against either the pilots or more likely the die cast Kadee mounts. That’s on O72 and even O81 curves. I don’t know if that would happen on other Lionel models. It probably depends on the model and truck length and placement
At any rate, I fixed the pilots in place as planned, filled the gaps and installed full railings. I also fabricated my own mounting pads for closer coupling. No rubbing or grinding from the wheels now. I liked the result so much I tracked down the other roadnumber and upgraded that one too.
