I would like some assistance in how to repair (if possible) a motor that has a broken copper connecting wire to one of the brushes on an analog loco.

I attempted to replace the brushes on two loco's, a 3095 and a rail bus (don't know the number) and when moving one of the wires out of the way to remove the brush, the wire broke at the top of the hinge point.

If there is a repair that I could do, or if you can recommend a reputable repair shop, that would be great! I live in the Philadelphia, Pennsylvania area of the United States.

Any suggestions would be appreciated.

Thanks!!
