It took me awhile to find a source for Bachmann’s lube and get it in here. I got it, applied it to the rollers, but it did little to improve the situation. However while working with the third rail collector rollers on the tender I did notice the forward roller on the tender had much more slop in the roller action. I will go for a new set for tender and engine after seeing how they can wear. Also I may consider replacing the rail sounds board after the roller change.
Jeff thanks for suggestion!
