There's a shortage of them, and every Southern Ontario train dealer has them on back order, AND everyone seems to overvalue their price. As a result, each DCC (...)

| | | | | 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 (...) (23 years ago, 17-Jul-01, to lugnet.org.ca.rtltoronto)

(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 (...)

Or connect one half of the connector to each rail in question (provided they are close enough, of course), and take an additional short Lego wire and "short" it - that is, connect it to itself at a 90-degree angle - and clip it on top of the (...)
