Trailing truck ground wipers.

If drilling and tapping it is not that difficult for you, that would be my preferred method.  You'll also want to run a wire from the wiper to the actual locomotive frame, the attachment doesn't do that good a job of grounding the truck.

Oh yea, definitely. I looked at the teather. In the tender side, a brown wire is unused, the tender has 2 pair of wipers, but on the engine side, all 6 pins on the socket board are used, most tied together on the PCB, I thought I may be able to get away with it..... 

For the price of a complete truck from a black tmcc hudson, it may be easier and just buy a new truck and swap it. Do you know if Lionel is still shipping part orders?

Pretty easy to just drill a small hole and use a 2mm tap to thread it, why wait weeks for a new truck?  Lionel is still shipping, they're just shipping slowly.

Yea, but don't have small taps, the spring steel/ copper or a nice black screw.... im thinking of pulling the ground from the tender, parallel teather. Just keep the tender attached.

Ok, I rang out the engine side teather socket, there is indeed a free pin that mates with the free wire in the teather. No continuity from that pin to the other pins and ground, so Im using it as ground from the tender. The wire gauge is the same as the motor lead, so Im not worried there, I'm a bit concerned about the ability of the pin to handle the current. But since its less than a second of interuption when the train does loose power, I think I'm OK. What say you? Thanks

 Most newer Legacy engines have a 2 ringed flexible wire on the pilot trucks frame. You can find pictures on their parts site. Could you go that route instead of the trailing truck.
