The whole issue of those archaic describers at Earls Court is just silly, imo. I understand all the issues about DMIs not being workable there - but as these arguments mainly centre around which platform the trains will arive at, I have an answer;
Why not have one DMI in the centre of each platform that displays the trains and their arrival-times (in minutes) scheduled to arrive either Westbound or Eastbound accordingly - and then displays the platform it's going to arrive at using an arrow (like Charing Cross Juiblee line used to) when the indicator knows the train is entering? If the trains change the order they'll be entering the station, they could just flash the "CORRECTION" message and update accordingly.
There really is no justification for the current setup there anymore, imo. This is a working station rather than a quaint museum. Sure - keep the old describers as a listed piece, but lets also have some sensible information for those people who have to actually travel from there.

The DMIs wouldn't need to be near the stairs, anyway - they'd be furthe rlong the platform, so there'd be no issue about crowds forming near the steps. People managed to understand the Charing Cross Jubilee DMI setup - so why not here?

What a waste of money. If Metronet couldn't put back the previous metal plates (which must have been pretty much indestructable) they might as well have put new DMIs in. This compromise achieves nothing and placates neither traditionalist nor moderniser. How about starting a new "heritage item disappeared by Metronet" thread? First submission: Bethnal Green's bronze roundel-faced platform clocks which were still there before refurb. Tim OT is right, LU's heritage is not safe in their hands.

People managed to understand the Charing Cross Jubilee DMI setup - so why not here? I agree with the new signalling when presumably all stations will get proper (some) information. The centre areas of the District platforms have numerous obstructions, two staircases to the Piccadilly, staircase to Exhibition Centre, mobility lifts, I'd say at least 7 DMI's per platform needed for centre use - which of course is do-able, but you still loose the space adjacent to each of those obstructions with no DMI in view, so still needing some platform side ones, there isn't the space for passengers to be gathering round these centre locations at peak times, this station is too busy for that. It beats me why people can't understand some of this stuff. It was as plain as a pike staff to me when i was a kid ! It remains entertaining to watch now the DMI's have been fitted at Tower Hill with this arrow indication ...the presence of an incoming train seems to hold more sway than a DMI with an arrow (not that the DMI is always right !)

I thought Metronet were back in tube hands? I'm sure there was a thread somewhere saying that...

All this talk of new/future signalling equipment improving the information at Earls Court is all well and good, providing the train service is right time. Once you have trains turning up out of turn, or the service goes to pot requiring re-forms, diversions, etc.....you'll be back to square one. Most of the re-forming, diverting....in fact all the general decision making on the District line train service occurs in real time at Earls Court and Barking. Perhaps that's an issue for service control to look at improving, but I can't see new signalling, dot matrix indicators or whatever else changing that. I thought Metronet were back in tube hands? I'm sure there was a thread somewhere saying that... Yes, but in real terms that's only just happening - all of the work done at Earls Court was purely under Metronet.

I've also got a couple of photos of that type but WITHOUT arrows, there's a three-column one at St James Park, being installed in 1905 - before the non-stopping came in in 1907. Much nicer than the 'originals' that these effete replacements are 'replicating'. ;D ;D

If the trains change the order they'll be entering the station, they could just flash the "CORRECTION" message and update accordingly. The problem is that on lines with 'Traditional' train describers, they have a limited number of inputs. Take, for example, somewhere like Hammersmith WB. The DMIs there do not show any descriptions until the previous train has left Barons Court - the point at which the Train Description is transmitted to Hammersmith. You will never see it display anything more than one or two minutes on the countdown clock. A similar situation would arise at Earl's Court, where the site is so complex in terms of number of places a TD can originate from and trains can be routed to or held at, that for most of the time a DMI would show nothing other than the default message - 'DISTRICT LINE'. Thus there is negligible benefit in providing a DMI, because it won't be able to do what it is best suited for - predicting train arrivals. That can only happen when a modern centralised control system is installed. As it happens, I was involved with the provision of the temporary train describers and the idea of providing a DMI was considered, but rejected for the reasons descibed above - the expenditure on the computer side of things wasn't worth it bearing in mind the limited functionality it would provide.

Something that sorts by destination (especially westbound) and has the time to the next train (or two) to that destination, and then a platform indicator. Having the time things move left as they get closer helps you to see which one should be first. Here's an example, showing trains in a fictional 10 minute period: Platform | Destination | | | Time to | Arrival | | | | Destination | Platform | <- | Richmond | Here | | | | | | 10 mins | Richmond | <- | -> | Wimbledon | | 2 mins | | | | | | Wimbledon | -> | | Ealing Broadway | | | 4 mins | | | | | Ealing Broadway | | | Parson's Green | | | | | | 7 mins | | Parson's Green | | | Olympia | | | | | 6 mins | | | Olympia | | space | for | | adding | | short | turns | | or | whatever |

All well and good, but you are missing the basic fundamental point - the current signalling system cannot deal with that kind of information - and they way the train service is currently managed would soon render it useless anyway.
It may do in the future......however with a site as complex as Earls Court and the way it is used by service control when the service goes off book; I don't think there will ever be a time when you will know with absolute certainty how far away your Wimbledon, Ealing, Upminster or whatever train is.
Technology is a wonderful thing, but there are limits!

Technology is a wonderful thing, but there are limits! <rantette> Very true - especially given that the current system was designed to cater for people who had the attitude 'if I'm going to travel by train I'm going to follow what the train does', rather than the attitude that has developed of late 'if the trains don't do what I expect them to do, I'm going to complain'. Unfortunately, society as a whole has changed - there is now a far greater emphasis on the wishes on the <ahem> 'individual' - people now feel they can fight for their own way and are not prepared to accept that the system designed for passenger information is actually pretty damn good, considering. High time that people took responsibility for their own actions - if they can't assimilate the information before them, then they should retire, cowed and put up the money themselves to improve a system. ;D </rantette>

All well and good, but you are missing the basic fundamental point - the current signalling system cannot deal with that kind of information - and they way the train service is currently managed would soon render it useless anyway. but there's the WTT as a guide, and you can find out (surely rather easily) whether a train has reached station x, which is normally y minutes away and display 'y'? OK, 10 minutes is quite a lot however 5 is definitely doable (have "more than 5 minutes" displayed). If the service is that messed up reliability-wise, then there's a serious problem that needs sorting.Doesn't Camden Town manage despite being a tricky junction? Anyway the displays on other lines normally poke around a bit - you get the second train being 5 minutes away for two or three minutes quite often! Certainty doesn't matter much, the illusion of certainty here is something worth having. Passengers would like a vague reassurance, rather than no idea, even if that reassurance is wrong sometimes (OK, often). And as the OP says, there's nothing wrong with Correction messages if service control muck about change the service.

I did some work on the PPP re-furb at Bow Road which incorporated the provision of train indicators. I learnt that, until the signalling is significantly upgraded, the only info available (electrically) is for the next train and only then when it is within a few minutes anyway. A colleuage of mine, Fiona Irving, was working hard to come up with a train-detection system to work independently of the signalling in order to provide some more meaningful passenger info. She suffered from the same problem as does anyone - that provision of wrong info is the worst crime, provision of no info when you've led people to expect some is the 2nd major crime. In view of that, guessing is no option. The truth is, particularly at Earl's Court, what we've got is all we're going to get until a new system is devised and implemented. Rather that than unintentionally lie to the passengers.
There is a completely secure train-desriber system integrated within the signalling system on the Central line. Even then, during disruption (when passengers really need the describers) the corrective actions taken by the control staff, especially last-minute changes, always upsets people. It was our biggest single source of complaints - for which my boss regularly removed layers of my hide. Train-desriber heaven is beyond reach I fear.

Earl's Court will be even worse when the S stock comes in - at least now you know a C stock is going to Edgware Rd and a D stock to the City (mostly).
And I agree about "stops here" - what's wrong with "not in service"?

"Terminates here" or just "Terminates" work in most other places. If that is too long, what about "ends here"?

This picture is interesting as ACTON TOWN appears to be in Johnston font? Exactly what we are complaining about with the "refurbished" ones!!
So, these describers have had at least 3 different fonts already, each different to the previous used.
Should we really be getting that worked up (myself included!) by something that has been done before?
Which era should they "refurbish" them to: 1908, late 1950s or all Johnston??

It looks like Parsons Green had an aprostrophe "'s" then, whilst the top inner two plates on both sides seem to be reverse-coloured Richmond and Wimbledon "non-stopping" indications.

. . . . .whilst the top inner two plates on both sides seem to be reverse-coloured Richmond and Wimbledon "non-stopping" indications. A certain enthusiast group for the Underground has in it's collection a few of these and they are coloured black & yellow + reversed, rather than the usual blue & white.

Another fascinating photograph !
I suppose a general non platform specific DMI showing merely "next Upminster train in aprox 2 mins" "next High Street Kensington train in aprox 6 mins" type of effort is possible .... The basics of that information is available via Trackernet ...perhaps a few large Trackernet screens could go up and save the costs of interpreting the info for a DMI !
The main thrust of our comments is that it isn't possible to display with any sort of accuracy what order the trains will finally arrive in, or, for trains originating from the city or Richmond/Ealing/Olympia which platform they will arrive in. For the most part, regardless of what platform or order the WTT shows them arriving the actual arrival pattern and platform is mostly determined about 10 seconds before the train arrives, whilst it is sitting at the home signal !
In times of any sort of disruption the destination of a train will often be changed whilst it sits in Earl's Court platform.
The functionality of DMI for trains originating from Wimbledon is erratic to say the least, for the most part it either assumes trains will appear in WTT order or in the same order they went to Wimbledon and neither assumption holds good for long !
The historic indicators are the best method that can reasonably be achieved for displaying the available info with a reasonable stab at accuracy for this specific location. They seem to have covered some plates whilst many have not been fixed in slots yet, but what I have seen looks pretty smart.

If they really wanted to tidy the sign up, instead of just stamping the TfL 'image' all over it with New Johnston, they could have replaced the blue on white signs with white on blue, or even illuminated versions of this. And made the capital letters. Not original either, granted, but tidier.

All well and good, but Trackernet is less reliable than the current set up! If I had a pound for every time the Trackernet screen at Upminster failed to correspond with what I can see out of the window, I'd be so rich I wouldn't need to work again!! ;D ;D ;D

You were indeed looking in the right place. The destination plates have been covered up (sort of papered over) - seen on Thursday 13/11. The 'arrows' are still visible.

How bizarre! If they've done that because of the wrong font and they're going to be re-restored, then why not just leave them 'as is' until that happens? Seems a bit Pythonesque to paper over the offending panels!
On the other hand, if they were covered up due to faults that would be entirely understandable. Not sure how much there is to go wrong with them though, they're not much more complicated than a domestic light socket and switch.

I see we're still stuck with the combined "High Street Kensington And Edgware Road" plate - that one is always guaranteed to cause confusion; it would be so much easier if it simply said "Edgware Road".
