Depending on the type of incident, I will generally ignore any instructions like that out of hand. If my judgement in an emergency suggests that the best course of action involves use of the EDR either for immediate evacuation and/or mandatory E-brakes, then I will use it irrespective of whether the train is travelling at 14mph or 140mph.
That said - Especially at higher speeds - I would try to form a safety barrier with my own body (Via using grab rails and firm footing etc) to replace the door that I was releasing and stop anybody falling out if they were caught unawares by my reaction to the emergency.
Another problem though - And one that this thread brings into the spotlight - Is that not all pax alarms trigger an emergency brake application (EBA) and actually stop the train...And applying Murphy's Law to that subject, here's how pax alarms can be expected to operate during an emergency...
- Where a passenger is taken ill, realises that they're on the wrong train, or something else that is best resolved at the next available station; The pax alarm will trigger the sharpest EBA in history and balls-up the train's computer in the process.
- In the event of a fire, gas/toxin release, bomb detonation or train seperation; The pax alarm will simply operate a blinking light on the driver's control desk and/or an intercom with no EBA whatsoever.
As a result of that and the fact a passenger never knows exactly what'll happen in the event of using a pax alarm, it limits the "known" options for the passenger down to a very small number. :roll:
Example: If I come across a passenger who's seriously ill and needs immediate detrainment at the next available platform, do I hit the pax alarm? If it intercoms the driver
without an EBA than that's
perfect...I can tell him what's going on, and request a stop at the first opportunity. If it triggers an EBA though, that passenger is f***ed...We'd be stopped in a place where the emergency services can't reach us easily, can't airlift the passenger out if it's an OHLE'd line, and EBAing the train only to restart it again would lose valuable minutes that could mean the difference between life and Death for said sick passenger!
Because of my uncertainty in this kind of situation and not knowing for sure if the pax alarm will EBA the train or not, my only option would be to get another passenger to attend to the casualty, run through to the front of the train as fast as possible, and knock loudly/force my way into the drivers cab to make my report!

To summerise this mass of a textwall:
Not only do all of these Bloody "abuse shields" need immediate removal on safety grounds, but the three seperate devices listed above for the S-Bahn need to be made available on our own trains as well. The handling of an emergency situation is mostly reactive 99% of the time, and not knowing whether the pax alarm will do what's
needed in any specific situation will cause passengers to waste valuable time determining whether or not they ought to operate it or the EDR.
And then of course there's the 30-odd minutes needed for the passenger to break their way through the "abuse shield" and actually
activate the device that they've identitfied as the most appropriate for the situation... :roll:
