I recently purchased a 2004 Williams NW-212 Switcher Locomotive (Reading) Cab #1512. I have never owned a Williams Loco before. It runs great, but it has a slight squeal / squeak that happens every now and then....like every 5 seconds.... Basically, it sounds DRY. Should I lubricate the gears from underneath? It has 2 motors.
Thanks for any advice.
