What about redundancy modes? I've come across various scenarios where traditional methods have had to be resorted to (one time the absence of functioning electronic brake control was undetected). I'm not discounting electronic brake control but the traditional methods certainly aren't 'obsolete'.ECP brakes are not EP brakes.
ECP brakes would detect a shorting of connections because suddenly the back of the train would no longer appear on the driver's desk display.
"Apparently the sleeper is running light engine tonight....."
ECP Brakes have two way communicaton down the length of the train.
So you can read status updates from every vehicle in the formation if you want.
The existing standard can even be used to control locomotives elsewhere in the formation, all over the same pair of wires (plus a power wire obviously)
