Original part of the Jubilee Line after extension

PEDs were installed on the JLE because the designers were worried that the air pulses generated with a full ATO railway would be sufficient to blow people over on station platforms as the train came in. The older section of the line does not have such high speed limits therefore less of a problem.

Also the older stations would require platform strengthening to accommodate PEDs and it would reduce the width of those platforms.

A matter of opinion

Not quite so with regard to heritage! Baker Street platform 9 and the lower circulating area was retiled in the late 1970s to match the fleetline red tiling of newly built platform 10. In the lower circulating area the old yellow tiling complete with individual 'Broadway' and 'Griffin' design tiles were hacked off before refacing the walls. However, on platform 9 the original tiling is extant as the new fascia was constructed about one foot in front of the original, the extended metal lathe mounted on unistrut framing and plastered to take the new red fleetline tiles. Thus at some future time others will 'discover' and perhaps uncover the original fascia complete with 1970s posters preserved for posterity!

I was lucky enough to be working on the 'new' Jubilee line at the time running new signal cables in the old Bakerloo tunnel and the new Jubilee tunnels.

I wouldn't call the 1970s Jubilee areas at Baker Street, Bond Street, Green Park and Charing Cross heritage yet, give them another 50 years!

The downside of the platform doors is that people now know exactly where to stand in order to block the exits for passengers trying to get off the trains.

I think it would be a good idea although expensive, to install PEDS from Green park to Swiss cottage. After that it is all overground so there is no point installing them in the open sections. I personally think all underground stations should have them to cut accidents and to put customers at ease when standing on a busy platform. Also with the Jubilee line being ATO trains come into the platform pritty fast too!

I disagree, the Underground is not generally equipped to take PEDs and installing them in the older station tunnels would be costly. Passengers who are uneasy should take care, stand at the back of the platform and/or take a later train. PEDs create issues of their own, they are not the answer to all the issues and on balance a risk analysis would no doubt highlight the lack of value for money or significant decrease in accidents in a potential allocation of finance to any retrofit programme.

What about PED's at the Claphams? Would be less costly than new plats, right?

Why PEDs only on the deep level stations? Surely the threat of electrocution is as great on surface.

A couple(?) of years back there was a trial of platform markings at a few stations to try and educate people about where to stand. I guess this was a failure?

The lattermost markings in that article appears very similar to the ones used by SMRT...
