@Landsteiner posted:I wonder if Lionel tested it on Fastrack and your tubular track is a bit tight at points, causing the stalling? Tubular track is much more subject to slight distortions of this sort, I'd think. You could test this hypothesis by measuring the rail to rail outer rail distance of different sections of your track and seeing if there is variation in the width, and if the stalling occurs at these points.
Interesting, Landsteiner, I doubt if Lionel tested it on O31 Postwar tubular track curves like mine.
I have many modern Lionel and MTH locomotives that were advertised as good for 031 curves, and they have all run well on 031 curves except for an MTH Susquehanna PS 2 or 3 diesel that is 18 inches long. However, the problem with that diesel was derailments, not stalling, on the 031 curves.
So, I have never had this stalling problem before. Arnold
