I plugged the red wire to the track. Bachmann has a curved and straight terminal rerailer that has plugs on both sides that you can insert the red wire. Here's a pic of my Bachmann 10" terminal rerailer (part#44820) with the red wire plugged in.
I'm not sure about soldering or welding to the track. I think the terminal rerailer or under-track terminal would work best.
