I’ve read that the firefighters turned OFF the lead engine, which was providing power to the air brakes.
Whether that’s the “tampering” he’s referring to , I don’t know.

As I understand it, the air brakes require air pressure TO DISENGAGE THE BRAKE PADS, so that any leak or loss of pressure would always lock up the brakes by design, for safety reasons.
So I think sabotage is very likely, eh ?

that is not how it works. Air Brakes use air to open the brakes, without air they are closed. Standard design for a 150 years.

turning off air brakes?
Ok, I'm not a railroad engineer but I thought that the air pressure was used to release the brakes so that in event of a broken or leaking air hose the default would be to engage the brake.
