Jubilee Extention platform door edges

[Simon11]

Hi

My sister asked whether it was worth installing Jubilee Extention door platform edges on every platform so that people don't jump in front of them meaning her trains aren't cancelled/delayed.....

The points that I thought up on the spot were:
-Costs of installing these ( How much would they cost per station?)
-People who wish to jump, would simple jump at another station
-Older stations, the doors would ruin it and some are protected

Anyone have more information?

From wiki
"The platforms saw another innovation: platform edge doors, to improve airflow in stations. They also prevent passengers from jumping or falling onto the line, but this was a secondary benefit, and not the reason for their installation.[citation needed] The platform doors occasionally malfunction and stay closed when trains arrive, leaving passengers unable to board or disembark at a particular station until the problem has been fixed."

The PEDs? Platform edge doors. I think they were mainly installed for airflow

there are two problems that I see, one is the disruption that it would cause, the trains would need to be modified, and stations would need to be closed during the work and what about here? the platform is far too narrow to accommodate 2 sets of doors

Yes, they were mainly installed for managing airflow around the large stations on the JLE.

The main problems are indeed cost of retrofitting to existing stations, disruption involved in carrying out the works, and also there might be an issue of whether existing stock would be compatible with PEDs.

Right now, the bottom line is, money is exceptionally tight (not that its not always tight anyway) - it can be better spent on other things. A little bit of common sense has generally worked to keep people off the track for the last 150 years or so - jumpers excepted, of course.

Also, there is an issue at SSL stations, where A/C/D stock share the same tracks - the doors on the different types of stock don't necessarily line up in the same place on the platform, so fixed doors would just be impractical. (Though this will be simplified somewhat when the new S stock is fully introduced, though there will still be different train lengths.)

it was definitely airflow on the JLE- notice they weren't installed at Stratford, West Ham and Canning Town.

Back when the Jubilee open each platform cost £1m. So to put them at other stations coupled with the issue of having to shut stations and problems that arise when you replace the rolling stock mean its unlikely to happen any time soon. Especially with the cuts.

As it was said above the JLE PEDs are there as the chespest way to manage airflows and have a benefit of keeping people and rubbish off the line.

Note that Crossrail's PED's will be more of a wall completely closing off the platform from the track.
