Having built a number of non-DCC reversing loops, I can tell you it's
pretty straightforward to jumper using track power leads, as Larry
suggests. It can get pricey if you're buying them from S@H, but I
expect most trainheads have more leads and power packs than they
normally need :)
I insulate using a layer of masking tape on the connectors at each end
of the track, making a 2-layer thick pad. I haven't had any problem
with wear breaking the insulation, but then, I've only run the
insulation for a few hundred cycles, not thousands.

(think about it, they run through) So you can get away with a track power connector that connects to just the two inner rails... depending on whether you have more (...)
