Train splits in two after driver told to ignore 'decoupling' warning
A peak-hour train split in two with more than a hundred passengers on board last week, after Metro Trains told a driver to ignore warnings that the carriages were about to separate.

In a rare safety incident being probed by rail safety and transport watchdogs, an X'Trapolis train carrying about 150 passengers broke into two parts while travelling to Lilydale early on Friday evening.
The last three carriages of the six-carriage train dislodged and ground to a halt between Croydon and Mooroolbark before 5pm. Passengers were on board but no one was injured.

What's quite strange about this is it was a clean uncouple. The couplers didn't break.
The rear set after uncoupling shut down completely which meant Metrol couldn't use the DTRS to talk to the passengers.

Fair to say a lot of head scratching is going on.

i would have thought the obvious thing would be to go through the uncouple and recouple procedure then if that fails a full system reset
