After reading another thread I decided to take a look at the grease on my PE. Opened up the bottom end and there was no grease to be found on the motor gears. Took care of that, cleaned everything up and back to the track.
Smoke works, sounds work (whistle & announcements) but the chuffing is barely sporadic. It actually chuffs more in reverse.
LOL, now what did I do?? Thanks!
