Then what? In this case, Suspend the train engineer? The company itself is incentivized to ignore the warnings to keep things on track.
(...on track)
A really important strike that Spanish pilots should do, is striking by respecting the red lights and refusing oral overrides. Hours of delays the first day, trains at the wrong place in the evening, we'd see exactly which regions are affected, and either we agree to repair things or we just leave trains to rot at the red lights rather than risking 900 people's life again (x2 trains = 1800).
>The company itself is incentivized to ignore the warnings to keep things on track.
If ignoring an alarm and keeping it on track "counts" as having kept things on track, there's the perverse incentive. Change incentive to mean a train kept on track after ignoring an false alarm was worse than a late train.
Now the company is as focused, or more, on fixing the bad alarms, than keeping trains on time.
Finding incorrect incentives is usually not that hard.
