My four-year old LC+ Rectifier locomotive started to have jamming of the gears, and rotation not smooth, No history of trauma. (Falls, collisions, things of that sort.) Really not operable. Moves short distance, then jams. I took off trucks and looked to see if some obstruction or broken gear, couldn't find anything. Anyone know who can do LC+ gear repairs/replacement with metal gears?
Thanks for any advice.
