Extra power required on door closing

I suspect many of our beloved customers think the doors will automatically spring open if they block it, rather like a lift. Not so. ;D

I have this theory....

There is an ancient and obscure regulation which few LUL employees are aware of. At a minimum of 80% of stations per journey a passenger MUST leap for the doors at the last minute. To facilitate this, each station has a little room - a green room if you will - just off the platform area and beyond the driver's line of sight. When the chimes sound a specially trained member of staff must sprint for the train and LEAP through the doors. In this way the regulation is fulfilled.

These staff are contract staff and while students and the unemployed often take some cash-in-hand leaping work it is clear that the vast majority are 'resting' dancers from the Royal Ballet School who are keeping their hand (or legs) in by executing graceful sideways leaps through the two inch gap between the closing doors.

Roll on the new stocks and the return of EDO!!!!!!

While on the DLR yesterday I noticed that the stickers informing you to keep clear of the doors suggest that they are edged with spikes.

As LT guards used to do, for example as shown on 'London Underground Remembered'. Doors would open while certainly no less thn 4 mph. Presumably our safety interlocks insisted on by HSE not only prevent it but are mandatory. Shame.

Just take into account that already the doors on the Central line are extremely powerful and have the potential to cause damage, especially to small children...

admittedly when it did happen it was when passenger door control was still enabled and it was a malicious person operating the close button that caused the child's horrific head injury at Notting Hill Gate.

The ideas of spikes and connection to the live rail will never be viable unless it is used just to make the door appear vicious - just have a sensor that makes the doors reopen as soon as there's an obstruction.

The 'spikes' would only be a deterrant ;D rather than being dangerous (although what if the sensor got covered up by dirt and didn't work? If someone got beheaded there would be unimaginable fines! )

I think the doors should be very fast-moving like those on Line 4 of the Barcelona Metro (these open in less than 2 seconds!) so that punters don't even have time to reach the train ;Dbefore their entrance is blocked!

but not so powerful that a child could be hurt.

And do I remember you suggesting it somewhere...

Interesting - I would have thought that CSDE circuitry would prevent it till (almost) at a stand.
