Have you experienced problems with your Polar Express engine derailing on certain sections of track or portions of their layout? Not so much perhaps with the drivers, as the pilot or trailing trucks. I've been asked to look into this for a friend who has this problem, but I can not reproduce it. If you haven't had this problem, but do recall discussion about it either here on OGR Forums or elsewhere, I would also greatly appreciate it if you would please direct me to that dialogue. Thank you.
