I discovered after a lot of trial and error and head scratching that I only needed one. I have one relay powering both reverse loops and it works like charm. If you try to connect two relays in the same circuit they will always see each other and keep trying to reverse the polarity continuously, causing a short. Hope this helps.

try resetting the switch after the train passes it.
this should keep them from shorting when the switch at the trains location is thrown.
also it is possible that the polarity of the loop is wrong preventing the train from proceeding.
