It looks like 20 or 22 gage, take a peice to radio shack, If i was replacing it I would just find and old computer serial cable and strip a peice out of it, if its it's too thin just double up on the wires.


Old serial cables are great for small multi colored wires.

The wire is probably 26 or 28 ga. if not smaller.  20 and 22 ga. is used in automobiles.

There are no dumb questions.

I was thinking 22 to 26 ought to do it, just make sure the new wire is very flexible and stays clear of the pilot pivot, and the slot it swings in, or you will have problems with derailments.

caution about using minimum wire gauge. I had the other guys Mallet catch fire because a sound board malfunctioned and the pickup wires could not handle the increased amperage needs. The take up wires and harness between the engine and tender overheaded and caught fire. Any wire used should be able to handle up to 10-12 amps.

I'm not certain what the original poster meant by ". . . the front wire . . .," but took it to mean that a wire between the front truck and the chassis was broken. The advice to use wire in the 24 to 28 gauge range makes lots of sense. The flexibility of the wire is what is most important, or the lead truck will not be able to follow the track.

adir Tom's post is recommending that at least #12 AWG wire (which is rated at 10 amps in 12 volt service) be used to reconnect that lead truck as well as connecting between the engine and tender. That would make it a little difficult (actually impossible) for the engine to go around curves or to follow the track at all.

Shows that you can get all kinds of advice on the internet. Some of it even makes sense!!
