I recently came across an older Bowser O gauge, 3-rail PTC trolley with number 5205 on it's side and lighted headlight at both ends. While the front and rear end windows and sidesdoors have no window inserts whatsoever it does have shillouetted side passenger windows. Trolley is all metal/steel construction with non-sprung brass trolley poles and made only to run in one direction with no reversing mechanism. It has no dates on either box or included parts diagram to indicate the year it was made but it's was obviously manufactured quite a few years ago.
When tested out on Fastrack, it runs very smoothly and quietly at all speeds but at times sparks at pick-up rollers.
My question is since the track is clean and nothing else sparks when run on it, is it because the trolley's pickup rollers are obviously sol worn that the sparking happens? Also, since replacement pick-up rollers are likely no longer available from Bowser can anything be done to the existing worn rollers to eliminate or at best minimize the sparking?
Thanks,
