A Sort Of Stuttering Unsensible Sensitivity......

Would it be the case that it's made worse by the alternating platform sides around Euston, King's Cross, Warren Street? If someone's coat is a little bit caught but not enough to trigger the sensitive edge, and they don't notice or think they'll free it at the next station, then the "wrong side" opens, they panic and try to yank themselves free triggering a problem on the side that can't be opened and reset?

Just a thought (and not mine!)

Because on *some* lines, the next train is also pretty crammed, and it then takes a while for the next train to arrive. If I needed a Hainault, and the next train happens to be a Hainault and overcrowded, and the only trains after that for 15 minutes are Eppings, I would definitely take the first Hainault one.

I heard this and was baffled. Reading between the lines, does it mean that the current management didn't want these trains, or that they didn't like the procurement process?

Sounds like you need to get that checked out by a doctor! ;D

On a more serious note there are so many safety features or procedures being cut back on to save time (eg setting back, platform recategorization...) and here we have a safety feature causing heavy delays that isn't being sorted out. The important note is that nobody has been dragged by these trains AFAIK

I know one of the trainers who was involved with these trains from the start. Way back then he knew these doors would be problematic, and he's been proved right.

Wasn't this idea tried out way back when - twenties, thirties? An idea abandoned back then and resurrected now, perhaps to be re abandoned soon.

Can't wait to see the EVO tube train. It's bound to have sensitive edges as part of it's driverless "safety" features "Roll up, Roll up! - Come see our new EVO tube set off from The Elephant. It should reach Baker Street sometime next year............"

I fully support sensitive edge. Its the best way at the moment to ensure that nothing is caught in the doors from the inside or outside. The likelihood and risk of injury is too high not to have it. The system is problematic at the moment (as any new system is when it is first introduced) but the problems will go in a couple of years.

If I was in charge I would of course get rid of the sensitive edge, and put black paint on doors so anyone that got caught in the doors would get a big black mark along them. But we live in the world where everybody sues so we can't live like that any more. Back in the day you used to be hit by a door and just get on with life as you knew it was your fault!

The problems will only go if passengers change their behaviour. Can you see that happening? If not, then the delays caused by these sensitive edges will continue indefinitely.

This whole thread is "Meh". Central Line still suffers issue with the doors and doesn't have sensitive edges. I've even witnessed it on the Jubilee Line.

Next train isn't plausible. Some days you can wait for 5 trains before you get one you can board even if they are one behind the other.

Unfortunately it's all health & safety. Either the doors are too safe and can cause delays or their are no safety systems and someone gets dragged into the tunnels because their bag strap was caught in the door and they didn't realise. Then typically TFL gets scrutiny.

Passengers don't realise. A 92ts had stopped at Leyton Westbound once, half the train had left the platform. I casually walked in between the train and the yellow line to find a man with his bag caught in the door but wasn't aware. It wasn't until I banged on the door and yelled "Your bag is caught in the door, you are delaying my day you useless man!" that he removed his bag and the train proceeded as normal. Door was barely open a centimetre.

He had his earphones on and quite simply wasn't paying attention like most passengers do and then blame TFL.

You should read up on why sensitive edge was introduced before asking that question.
If a door closes you will get a pilot light. However there could be a bag strap or coat toggle stuck in the doors. Sensitive edge will prevent accidental dragging of such items stuck in the doors.

Yup. Indeed. Although all the problems need ironing out... and perhaps people should try to jam themselves into the train further while we're hearing the beeps and when the train starts driving move more towards the doors.. or just have all tip-up seating on the Vic.

By making it less sensitive and relieving the Victoria line as a side effect?

Leaning against the doors is a different kettle of fish that affects the door proved closed circuit. Sensitive edge is like a bolt on if you will.

I think the reasons for accidents happening before like people getting killed because of stuff caught in the doors and dragged into the tunnel was that the trains didnt have door closing alarms then and they didnt know the doors were closing

I will not regard that comment as quite frankly I think it is flippant.



Lets just get this clear, If someone gets their arm/ head or bag caught in the door that will cause the door to open and close 3 times (Obstacle detection)

Sensitive edge only happens when the door is proved closed and locked and something is stuck in it and pulled, like a bag strap, etc.

I wonder, when we got rid of slam door stock there was a big uproar about electronic doors... "Oh, someone is bound to get their head stuck in the door", "When will we know when the doors are closing as we can't close them ourselves", "I'm never going to get a seat as there are not as many doors as before".

Obstructing the doors will always happen, people will always run for the train when they hear the door chime, that's just a standard re-opening procedure if something large is caught. A safety system for doors closed and locked and a thin item caught is here, and we can either embrace it and go with the times as things evolve, or be stuck in the 20th Century - Where there will be no detection and possible deaths/ Injuries just as before. 1 death in any transportation system is 1 too many. We have to learn to advance, we've learnt that people get straps in doors, now we have a solution to stop a train if that happens.
