The other day I was using platform 1 at Baker Street and noticed for the first time flashing blue LED lights at platform edges. I presumed its to highlight the gap at the platform edge in these modern days where people are too busy texting, checking emails etc on their phone that they don't notice things like gaps like the example of the woman who walked straight into a canal in Birmingham . Does anyone know if this is being rolled out across the network or just certain stations?

It's a trial, with the results still being gathered, to see whether it reduces the issues we're having at the PTI, so it won't be rolled out across the network, but if some good comes out of it, perhaps at our hot-spot stations (currently Baker Street, Farringdon and Finchley Road), but you've got the general gist as to what it's meant to do.
At the moment, I find all it does is attracts people's heads to the doors and side of the train just as I'm about to close the doors or move off! Even I find myself mesmerised by them when I'm changing ends and they've earned the nickname "disco lights" by some of us!

the platform edge lights are found in WMATA as well
so anyone has recorded the new lights in Baker street?

Sadly shades of red, orange, yellow or green would not be permitted even if the lights only illuminated once the train had stopped.

I just came on to the forum today to post about the blue lights and found this thread already !
I saw them first about just over 2 weeks ago. I didn't post then as I'd intended looking to see if it was only pl.1 or others, then for whatever reasons did not use Baker at all last week. And it is pl.1 only well at least it was this evening.
Now it is darker after clock changes they are even more attractive to punters, you see people trying to peer between track and train to see what they are.
They are horizontal LED strips that flash on and off in a 50/50 cadecne, but that cadence is lamp by lamp as far as I can see, does not appear that adjacent lamps are anything but randomly phased.

On colours, the blue stands out as it is different.
People are used to seeing blue lights on emrgecny vehicles.
I'm not sure you'd want arrays of red (or yellow or green) LEDs where colour light signals are still in use, even where a train is occupying the platform, maybe on lines where trackside signals are no more they'ed be less of a signal sighting risk.

Would be good on Farringdon Thameslink platforms too, as well as Met.City. platforms.

IIRC Mind The Gap is accompanied by an illuminated gap.

Video (quite brief, but you get the idea): www.flickr.com/photos/version-3-point-1/10653996985/ Anything but blue would be a bad idea if I'm honest. Red risks signal sighting, and any other colours would have to be carefully decided, though lunar white could also work quite well. The lights do not illuminate until the train is correctly berthed and stationary in the platform, and the lights immediately extinguish upon departing (they come up very clearly in the in-cab CCTV). |

well in WMATA - the LED lighting on surface not underside of edge but in prague - one station has platform edge lights flashing before the edge of platform - example
Wmata has red lights (former was White) - this could applied carefully -
those solutions would be great and show passengers a warning of gap

I think blue is a standard colour for the edges of walkways. You see them on the floors of some new trains and buildings.

The gap between the new trains and the platforms is causing problems at more than 40 sites. Some are worse than others.
Not sure but the lack of a step up may be making things worse as concentration is not always as it should be.
Flashing lights may be a distraction.
At some of the sites the under platform lights are not yet lined up with the doors.

I never quite understood where there is a raised platform hump at some stations , why they can't just raise the whole platform (I say *just* i'm sure it's a major and expensive job)

It's cheaper just raise a part off the platform but I do agree, they should raise the whole platform.

It's curved platforms that are the problem. The access is now level as the trains have smaller wheels.
Humps are only needed on Tube stock platforms where lifts have been installed.

They only need to raise the platforms were there us going to be demand for it, ie. level with the car with wheelchair spaces in it at stations with lifts.

Of course such fittings are not as yellow as 'yellow lights' and become less yellow the longer they are on. |

At some of the sites the under platform lights are not yet lined up with the doors. Strange that the 'Gap' has become an ever more troublesome issue over the years, IMHO that is entirely due to poor design of more modern rolling stocks and/or the make do and mend approach to station modernisation in preference to rebuilding and/or realignment of platforms. The railway is where it is of course but over the decades many opportunities to improve the passenger experience have been missed by a failure to invest in the future in order to save money. |
