Wiring to tenders pickup so engine won't stall in switches?

My Lionel WC 3547 4-4-2 has electrical pickup on the tender for its air whistle. Would I be messing up its wiring if I ran 2 wires from the tender pickup to the drive wheels pickup so it won’t stop dead in the 042 switches?

Not at all. I and others do it all the time. But why two wires? If you’re thinking about wiring the frames together, that will probably not give you any noticeable further improvement.

You can make an easy and unobtrusive single-wire tether connector from a male-female pair of connector pins (not the connector–just the pins). Solder them to black wire and cover all but the business end of the male pin with black shrink tubing. Put the female on the locomotive so that you can test-run it alone with out having the loose end fall on the track and make a short circuit (as I found out the hard way).

I already have some RC small male/female connectors to do this. I was thinking of just an electrical connection between engine and tender.

Read new CTT.

Which month? I buy them now and then at hobby shop.
