DCC TWO ENGINES RUNNING OPPOSITE DIRECTIONS ON THE SAME TRACK - Model Railroader Magazine

As has been (over)stated, it is altogether too possible to have two DCC-equipped trains running in opposite directions on the same single track.

Unless you only operate a single locomotive at a time, the book, Rights of Trains, by Peter Josserand, should be mandatory reading for all operators.  While it goes over every possible operating rule in exhaustive detail, the basic messages are loud and clear.

YOU DON'T TURN A WHEEL WITHOUT PROPER AUTHORITY.

YOU DON'T ENTER ANY TRACK IF YOU EVEN SUSPECT THERE MIGHT BE AN OPPOSING TRAIN ON IT.

Since, unlike straight DC, it is possible to run any train in any direction at any speed anywhere with DCC, it now becomes necessary to run like a full-scale lokfuhrer rather than a toy operator.
