I have noticed while running my trains fast (MTH and Lionel) on one of my loops that the rollers were sparking, particularly at high speeds.
I have cleaned the track, rollers, and even swapped rollers with another engine and no change. Most of my command control and have sparking at high speeds and with the cruise control turned off at high speed. The engines run fine otherwise.
Anyone tips on fixing this issue? My thought was, which I've had before, that I was going fast and the rollers were "jumping" at track joints but even on the extra long straight sections I see sparking. I have cleaned the roller, wheels, and track. Any idea this may be connected? Is it possible that at high speeds there isn't as good of a connection? Thank you for the help.
