Those who don't know how the railways work don't understand whether the train is protected by signals in these situations or whether another train could cause an incident. After 90 minutes, another passenger was going to exit the train. We talked them down to activating the passcom instead. This suddenly generated action from both the guard and driver who were consumed with rage that the passcom had been activated. Why could they not have done a PA or at best walked through the train once in 90 minutes?
I was on a 450 once that got stuck outside Clapham Jn for around half an hour because of (presumably) a weather-related power cut.
The DC supply was operational at all times, however reaching the facilities was easier said than done (it was rather busy due to most trains off Woking being cancelled due to the weather).
450 aircon isn't exactly the best at coping with large numbers of people so it was really hot and sweaty. The guard and driver just hid in their cabs with the windows open and didn't say a word, even after someone pulled a passcomm. I had to phone friends to find out what was going on (we were in the cutting so phone signal patchy at best).
Seeing 455 drivers and guards stuck on the slows with droplight windows open just rubbed it in. I get quite severe anxiety so any longer than we were there and I would have absolutely lost it. I needed to get off. I'd also run out of water.
Had we been there any longer, we'd have had to open a door for our own safety. It may not be the answer you want but it's the truth. Someone having a major panic attack and potentially passing ouy in a cramped carriage or opening a door for fresh air when nobody's moving anyway. I know what I'd pick and that's the truth. All that would've been needed to stop us feeling like that is:
a) telling us what's going on and acknowledging we still had two live traincrew
b) aircon that keeps you cool and not sweaty when it's 20-odd degrees outside.
Hence it's perfectly understandable.
