I recently got my layout together and I used FasTrack because I wanted the wider curves. Some of my curves seem to take issue with the newer flyer equipment with the fast angle wheels. Postwar equipment works well no matter what.
Basically the new wheels chatter and the trucks seem to hang up on some curves. Anyone else run into this? I'm wondering if the rail spacing is off.

Some early production runs of 27"R FasTrack allow the wheel flanges to hit the molded plastic mounts that hold the rail. The worst engine I have is the newer Legacy PA/PA set. Its flanges even hit on the old SHS 30"R curves and will derail. I think fast angle wheels is a design unique to O gauge but not all the Lionel S gauge wheels are the same. I have never had a problem using SHS track with any Legacy steam engine or U33c, U36c, ES44 or SD70ACe diesel. Many of these engines will bump along on the Lionel FasTrack 27"R curves.
With the exception of the Legacy PA the issue is the track, not the wheels.
I assumed it was the track and not the wheels. But someone on a Facebook group also mentioned the ties being an issue.
It seems like the issue I've ran into with Super O. Some flanges don't like it.
Some folks have sanded down the molded tie spikes on the 27in curves and eliminated the problem.
That would fix it.
"Molded tie spikes"? Do you mean the little humps of plastic holding the rails in place?
Some of my Polar Express car rumble, engines ok.
Yes, those are what cause the problem.
Dave from Lionel provided a production date code on the wider curves that had the issue resolved and eliminated the problem. I brought this up years ago and a search of the forum should provide the code.
