Could two track nails along side of a track joiner be the the source of a
electrical short? I put two nails alongside of track joiners to keep the
curvature of the track.
I believe You should look at the other threads that You started. One in Electronics & DCC and one in General Discussion. You may find Your answers there.
No, not a problem - assuming the nail(s) touch only one side of the track and are not touching any wires or the like.
While you didn't give specifics, I assume you have a "short". The usual suspects are feeder wires crossed, a car/loco derailed (or with an internal problem), something left laying on the track, etc.

Not if it's just nailed into something like plywood. But...
Back when I was a kid, we had a mountain on our layout, made with the plaster over screening method. Halfway up, there was a flat area on which my Dad built a short back and forth track that went in a portal at one end. He nailed the track down tot he plaster. And it was an instant short on the power pack. Ooops. Some of the nails touched both a rail and the screen underneath.
