I have 3 track o scale track - my train "runs out of steam" on the other side of the track. What gauge of wire would one use to run to a power clip away from the original? Do you hook it up to the transformer or to the first power clip??
Err... AWG get smaller as the number go up, right? So wouldn't that be 12-14 (more copper) for the main "bus" wires, and 18 (less copper) up to the tracks? If you're only running one engine at a time, you can use thinner wires, if that saves you money. Suggested wiring would be: (ooh! ascii art!) <tt>Controller ----+-----+</tt> where <tt>----</tt> is 12-14 gauge and <tt>+</tt> is a join to the 18 gauge which leads to the track itself. Of course, there's two wires, so it looks more like <tt>====</tt>. Does that help?
