Discussion of "electric" air brakes is interesting. New failure modes etc. That Australian ore train runaway appears to have been a case where electric continuity broke causing a penalty application stopping the train on a grade. However, for battery care reasons, the system cleared itself after (an hour?) - so since the engineer appears not to have made a manual emergency application before leaving the cab, the brakes released and the train ran away while he was outside looking for the break in the wire.

When stopped on a grade, is it done to leave the dynamic brakes set so if the train starts moving they will kick in without further attention? If that works, it might at least reduce the speed a runaway can achieve on moderate grades. Assumes of course that there are enough locomotives with working dynamics on the train to provide a decent amount of braking.

The ideal, of course, would be for ECP brakes to be compatible with non-ECP brakes so the cars can be used in non-ECP trains.
