This vulnerability would have to trigger the airbrakes, which every single railcar has, and every car’s airbrakes are daisy chained together. Airbrakes are failsafe, in that any loss of pressure results in brake application, and a full loss of pressure means full application. So if just one car on the train has a problem with its brake lines, the whole train is stopping whether the railroad likes it or not
Joke’s on them, 50% of the brakes don’t work.
