Exactly, ....twist bus wires and use a snubber at the end to protect your decoders...... what most of us have been saying from day one.

Therefore the energy kick-back of a short circuit and the potential to create damage becomes greater when the DCC bus wires are separated rather than tightly run in parallel. (Twisting the wires together keeps them as close together as possible with minimum inductance.) And, since the short circuit current is supplied by the booster, the stored energy kick-back issue becomes greater as the location of the short circuit increases down the length of the DCC bus away from the booster. This is the primary reason why the snubber works better if placed at the far end of the DCC distribution bus.
