Platform Gates.

Get a crowbar/baseball bat or other harmful implement and smash your way through nah but, I'm not sure but I would of thought atleast one door set would be lined up with the gates in case of de-trainment. Dunno really though, sorry.

Also the additional costs of installation and maintenance would be taken into account as well.

They are platform edge doors, as opposed to gates. Gates are half height, and quite common in Japan. The train has to accurately stop within a defined area (? 50cm). The train then communicates with the PAC, which then tells the doors to open. When the driver closes the doors, the platform doors close in unison. When both are detected to be closed, then the train can depart.

The website for Westinghouse's platform edge doors is here www.platformscreendoors.com/psd/services/


The driver manually stops the train within the limits of alignment. The Jubilee was supposed to be ATO, and the HSE say that PEDs are not allowed on manual lines.


If the train is too short of the accurate stopping point, it advances to the accurate stopping point. If it has overshot, it has to carry on to the next station.


Although the train could completely stop out of alignment with the doors due to an adverse incident, you would be quite unlucky for it to happen, as the platform doors are considerably wider than the trains doors. I think the doors can be manually opened by a station assistant, or by passengers using emergency open switches on the train side of the platform doors. There are also platform end doors to be used if passengers are detrained onto the tunnel emergency walkway.


Er, it arrives at Green Park really.

The PED's on the JLE have paid for themselves already by reducing service delays and suspensions caused by people and objects falling, jumping or walking on the tracks.

In my experience they are a bit of a nuisance !

Drivers understandably creep into platforms...stop, creep forward ...stop ...creep forward a bit more, trains stops for ages ....eventually doors open ! if you are lucky !

I have been on several where the train doors have opened but the PED's have not .... only once when I'm train side ...and i did use the green release button on the PED's. I was away and gone whilst the train just sat there !

Conversely numerous times train doors close but the PED or a single PED does not

For a while i tried the Jubilee from Westminster to West Ham in attempts to by-pass the close proximity stations and slow moving District and congestion around Aldgate junction. Every time, the Jub trains sat for so long at each station the District would have proved quicker ! I now stick to the District for such trips.

It's a good job we don't have those PED's on the District ... I'd have to real modify my driving ... Stopping Mark What stopping mark ? You mean that thing 1/2 way down the first car ;D ;D ;D ;D

As I mentioned earlier, the HSE will now only allow PEDs to be installed on lines with ATO.

The software upgrade was so that the PEDs computer opened 7 cars worth of doors instead of 6 cars worth, when the door open signal is received. Pretty simple really!
