It surprises me as pneumatic systems on 18 wheelers are made especially so that once the air goes out of the system the parking/emergency brakes are activated by a mechanical system.
That's interesting, thanks for filling me in on this. It just seems to get stranger and stranger by the minute.

I also understood that the actual locomotive part had detached from the rest of the train and just kept going down the tracks to stop many km's later where they were able to retrieve the "black box", similar to what they have on aircraft to help understand what went wrong.
