In a sense, the rollers to the third rail are like trolley poles. If a trolley is running at a higher speed, the bouncing trolley pole and its contact wheel could produce sparks like the rollers on the thisrd rai.

Thanks. Good point, one that I was curious about. Is going fast causing the rollers to "bounce" a bit. With their smaller size, they are spinning quite a bit faster than the wheels!

Also forgot to mention that I put the rollers for a brand new, never on the track engine on one of my older, well run MTH engines - still sparks even at quick speeds. I note this at quick speeds and at "full power" operation!
