The point is that the automatic brakes should have stopped the train, when the alarm was put out that wheels were on fire. The human alarm was overridden by the fat controllers: the train drivers were told to keep going. This is not a muh Trump deregulation issue, but a greed issue. Stopping a train is sooo inconvenient, as it will cut into profits. Plus, the train crew had the fear of employment loss put into them by the Biden administration. Any disobedience would be seen as strike action, and a subsequent firing. So, a train-driver who is told by his bosses to disregard the wheels that are on fire, must continue, or lose his job.

This sort of thing happens when one takes away the discretion of those working on the ground. Any sensible person would have allowed the automatic emergency brakes to work.
