Just another tube journey home, rattling steadily eastwards, and I'm slouching at the end of the carriage reading the paper. The train's not packed - it must be August - but otherwise it's an entirely unremarkable journey. At Bethnal Green the doors swish open and a few people storm off onto the platform, hurrying escalatorward. The train pauses, and those of us still aboard wait for the doors to close so that our journey can continue.
"Ladies and gentlemen..."
Hmm, that's not the normal platform announcement voice. He sounds somehow different, more posh, more precise. Normally we get to hear someone a bit chirpier, someone who sounds like a real human being you might meet in a pub and not just a stilted robot. Even the nannying lady who repeatedly nags you to take all your belongings with you has an air of the 21st century about her. This bloke could be straight out of a 1950s documentary, probably wearing a bowler hat. I wonder what he's going to say next.
"...because of a reported emergency it has become necessary to evacuate this station."
Ah. Hmmm. Ulp?
I look out onto the platform. There's no obvious sign of danger, no billowing clouds of smoke, no crack police team in gasmasks, not even a lonely looking rucksack. By now there's barely anybody left on the platform at all, just a silent tiled wall staring back at me. I wonder what the emergency could be. Is the world ending, is there a gunman on the loose, or is it just that the driver's radio is on the blink again?
It's not just me. Everybody else has stopped reading and is now looking up. Eyes dart nervously around the carriage in a flurry of reassuring communication. Some people smile weakly, others appear rather more nervous. We are all going to be alright, aren't we? Go on, tell us more.
"Please exit the station immediately."
Erm, how? Should we all rush off the train and head towards the escalator (not good if the unspoken emergency is up in the ticket hall)? Or should we all stay on the train and wait for the driver to zoom us out of here (not good if the unspoken emergency is in the tunnels)? There are no clues.
The automated message is not repeated. Mr Posh has no more information to impart. There's no obvious member of station staff around to ask, nor any human being speaking over the station's tannoy with specific evacuation information. Even the driver is staying mute, perhaps because he knows no more than we do. This might be a false alarm for all we know. Or there again it might not.
We sit, and stare at each other, and wait, and wonder whether anybody else in the carriage is going to react. Nobody does. The doors are still gaping open, tempting us to stand up and escape, but we ignore the opportunity. Come on driver, slam the doors shut and whisk us out of here. And quickly please.
It's strange, but even though the voice reading the announcement was firm and proper, everybody has ignored him. We've all heard far too many automated announcements on the underground recently and we've learnt to disregard them. Planned engineering works? Don't care. Take our belongings with us? Yeah yeah. Don't change trains at Bank? Not listening. So when a recorded announcement tells us to evacuate the station, we don't take a blind bit of notice.
At last, after what's probably thirty seconds but feels much longer, the doors finally close. We set off into what we hope is the safety of the tunnel, keeping a close eye on any potential nightmare unfolding on the platform as we accelerate away. No sign. A brief perturbed smile from everyone in the carriage - what happened there? - and then back to reading the newspaper. No worries.
BETHNAL GREEN STATION. Closed due to a fire alert. All trains are not stopping.
Nothing dangerous this time, but in the event of a genuine "situation" we'd have been buggered. The general public appear to have no respect whatsoever for someone pressing a button to play the emergency tape, because familiarity has bred contempt. The unexpected, it seems, has to sound properly unexpected to be taken seriously. And one day, on some train in some platform somewhere, I fear passengers may not believe it's the real thing until it's too late.
