That's an unusual line diagram, with the Circle line unravelled!

They should do something about segregating exit and ingress passengers,most of them leaving the H & C platforms ignore the official way out and use the way in to the platforms to exit,this can be pretty hairy in the peaks esp if the service is up the wall.

Anyone in their right mind would use the Victoria Line and change ;D The platform/station timetables do have the journey time for each direction (up to the half way point), perhaps it would be a good idea on the Circle Line where the whole line is shown on those signs, to publish to the journey time on those signs?

Link it in to the next train display and have dot matrix live "estimated journey time" indicators by each station, smiilar to the way signs for car parks tell you how many spaces are free.

Too much information! Just a DMI in the ticket hall area (before fare control) showing next 3-4 trains on all lines would suffice.

Watching TV the other evening, I now believe that the bloke doing the automated PA announcements is the one who voices "The Weakest Link." The automated one has a bit of an accent, but I think that could be down to the way it was recorded / put together.
They definately sound similar.
"Jane is statistically the weakest link but will the group notice." "There are delays on the Piccadilly Line due to signal failure."
;D

DMI's [or VIDS-visual information display system] are becoming increasingly common. Kentish Town and Tufnell Park have them. They are great in times of disruption, giving pax the choice to use the service or not. Not so great is [for example] it shows "Morden via Bank" 1 minute. Everyone then charges down the escalator. Not good.

You're right though its a good way of choosing the bus or train

You could just delete the train from the display when it gets too close for people to catch it without risking their necks. This happens on the District line at Upminster - only problem is when the train supposed to leave imminently doesn't.

This happens on the District line at Upminster - only problem is when the train supposed to leave imminently doesn't. At most 3 track termini (where there is a chance of ending up on the "wrong" platform if you just miss a train), the display only changes when the train to depart has a green signal. Hopefully, with more advanced signalling soon to be installed on many lines, the system may be able to be a bit more predictive.

This has been a pain in the proverbial for many years and has defied all attempts to fix. I used to live at Hainault where, too often, I'd follow the sign only to see a train leave from the opposite platform because the starter was clear but the train hadn't left. I can't think of a more efficient way to p*ss off your customers. We used to use this scenario in interviews to see if applicants had thought about this kind of thing. Apart from a loop (a'la Kennington and, a long time ago at Wood lane) does anyone have a 'modern' answer?

Hopefully, with more advanced signalling soon to be installed on many lines, the system may be able to be a bit more predictive. I believe that is how it works at Upminster. The trouble is the signaller will sometimes clear the signal as soon as the train is berthed in the platform. On some occassions by the time I've got out of the cab at the East end the signal is already green. You have to admire some signallers' optimism!

Apart from a loop (a'la Kennington and, a long time ago at Wood lane) does anyone have a 'modern' answer? Predicting terminus departure times would not only help passengers end up on the correct platform, direct passengers away from the closing doors, and allow drivers to start the door closing sequence before a green signal has been given. Thus it would have many advantages in terms of on-time departures, reversing capacity, and customer care. Predicting the train departure time, and thus directing passengers to the next platform/train accurately, is a lot easier of there are not any potential conflicting train movements in the path of a departing train. The problem is also non-existant if all trains depart from one platform (e.g Bank, DLR or Waterloo W&C). A layout popular in Paris and Mexico City is to have 3 tracks, with trains reversing in a siding(s) between outside tracks, whilst a train can reverse in the centre platform track. This allows for a very high turning capacity, and no conflicting movements. Thus the departure time can be accurately predicted. Only one existing LU terminal could be modified for this type of operation, and that is Morden. The disadvantages of this type of terminus operation (e.g trains departing in a different order in which they arrive) could also outweigh the advantages. For the other existing termini, the departure time could be predicted by use of track circuits, axle counters, or other train location equipment detecting the position of the incoming train, in conjunction with computer based signalling control. An example being at a typical 2 track terminus, the train being detected within 15secs of clearing the crossover, and the signalling system knowing that the train is within 15secs of planned departure time, would change the "next train indicator" and signal to the driver to close the doors. At 3 track termini, this may be more complicated, as the "next train indicators" on the concourse may have to change approx 30secs before departure, but less than that on the island platform from which that train is departing.

At Mansion House years ago, when the signalling was controlled from the local signalbox a sign at the barrier showed "Next westbound train from Platform 1" when a train was leaving from the Eastbound platform bay.This was worked by the Box Boy.
This 'personal service' is difficult to provide with a computor!
It should be remembered,however, that in the rush hours the departures are arranged mainly for the benefit of the rest of the line and not just for the benefit of a handful of passengers who might be delayed a couple of minutes.

There was of course at one time a three-way "NEXT TRAIN" indicator at Hounslow West for the original three platforms, and then this went down to two with the Hatton X extension as it then was. We used to see which train had a green light and go for that and ignore the display!

I see they've switched on the permanent lighting on the H & C platforms,don't like it much,makes the platforms look very shadowy,also they've widened the staircase to the Western ticket hall.

Just had a thought: instead of the departures board resetting as the platform starter clears, how about it resetting as the train loses contact with the CSDE loop as it departs? Still far from perfect but resetting is much closer to actual departure time, albeit the wrong way and encouraging 'runners'.

Not really feasible, the loop is 'dumb' and doesn't detect the train sitting there.

Where will the behind-barrier link between the subsurface platforms and the deep level platforms be located?
As far as I can tell the original subsurface ticket hall is still present, but the corridor where the stairs used to be is now all finished up with no signs of temporary hoardings...
Also, the new Western Ticket Hall under the St. Pancras cab road appears to be a little bit oversized for its current use - are there corridors hidden behind false walls that lead either to the Eurostar ticket hall, the Domestic ticket hall, or the Thameslink platforms?
Finally, what's going on behind the hoardings next to the Vic Line escalators?

I believe it's going to be at the West End of the Met and Circle Platforms. I'd like to know what is going on behind the hoardings, I had to get a cable going right through there diverted and I was under the impression that it was the only thing holding up the works.
