@stan2004 The PS3 non-coasting issue really bugs me and I don't believe it was ever resolved. MTH is pretty quiet about it; i'm not sure it CAN be resolved. I can't find the link now, but a long time ago I came across a video in which a fellow with serious machine skills created custom "slugged" flywheels for his Atlas SW switcher by inserting tungsten fly fishing weights in a circular pattern near the outside edge of the flywheel. (Picture bullets in the chamber of a revolver and you'll get the idea of what he did.) Having the additional mass near the EDGE of the flywheel makes all the difference. However, I can only imagine the precision it would take to do this and keep everything balanced. I've replaced stock flywheels with larger ones, and getting them on straight is a chore. Sometimes it's necessary to improve the balance by holding a file to the flywheel in situ, while it's in operation. Crude and approximate at best!
@Engineer-Joe The Lionel Legacy locos with BACK-DRIVEABLE gears are a better choice IF they make the model you want, and IF you don't mind Legacy instead of DCS. It's true that the dual flywheels found on horizontally motored locos have more mass, but especially in the smaller scales, they are probably turning a lot more RPMs. If the manufacturers would wise up and get away from the toy train gear ratios, I think you would experience more coasting and consistent speeds, even without gimmicks like capactiors and speed control.
