I have a Lionel Classics Blue Comet from 1991 that I've been trying to service the whistle for. The relay does work and activate the motor, but the motor itself really hesitates running, and even when it does, the sound is very, VERY anemic. The motor itself makes more noise than the whistle sound.
I have a feeling the motor brushes need to be changed, since I have given the motor armature a couple drops of oil. One of the springs isn't seating the brush as strong to the armature as the other. Are these whistle brushes and springs universal? I'm looking on Trainz and they have the WS-147 springs and 1661E-19 WS-110 brushes, so would these fit this?
