> On a typical "modern" (ie late 20th century) train like the mainline EMUs I would normally catch when I was a commuter decades ago, the equivalent "cut out" is a glass sealed MCB in the cab, a driver who wants to get rid of this safety feature has to destroy a tell-tale glass seal and company regulations will make them write up why it was necessary then replace it - and of course the automation records each occurrence because why wouldn't it. The paperwork is a faff, so is getting a new unique numbered seal, so drivers actually choose the non-risky option when it's available.
Fun fact: in Germany, the now-infamous company Die-Lei GmbH lost their license to run trains after a few accidents where a side finding was that their trains kept running with PZB (a magloop system halting a train when running a red light) disabled, sometimes for hundreds of kilometers and weeks worth of operating time. It never was a contributing factor in any of their incident, but the persistence of these findings was enough for the railway safety authority to yank their license for good.
YouTuber and former loco driver Alwin Meschede has a (German) video series where he narrates the investigation reports and the final license yank order, while drinking a gulp of wine for each violation [1].
