All these polarity-switching solutions presume only 1 train.  If you've
got 3 trains, and each of them is hitting a block boundary at the same
time, you're going to have a short no matter what you do.

Best solution for DCC is to get your insulated sections exactly the
right length and not have more of them than necessary.
