i have been wondering this for a while, but it seems that all other stations towards the extremities of other lines (e.g northern, district) seem to have the platform dva which announces "next train to X will arrive in...." etc.
My question here is that going south from northwick park, the dva seems to be present at all stations, however north, there are no platform announcements at all, not even at harrow! When were these kind of dva's installed, why are they still not on the met in the north and are there any other sections of other lines that are yet to recieve them?
I realise it has been said before that it is the signalling system that prevents this, but almost EVERY other line includes these features, it just seems to be the met. Other parts of other lines still have this info despite runnning ancient signalling such as the bakerloo and piccadily itself!
This question occured to me as i was recently travelling to eastcote from acton town and have noticed that recently, all stations on the branch now show the timings of the next few departures on the dmi, along with station dva's upto south harrow, from here onwards, no information is present at all, rayners lane does not even have a dmi which is extremely surprising as its an interchange station. Also rather suspicious that the point at which this useful information stops is where the the northern section of the met joins in, does this information have have some kind of problem against the met? (LOL)
If this info can be shown right up to south harrow, why isnt at all shown on the uxbridge branch at all, its only a matter of a few stops more and would be alot more useful as there are two lines on the same platforms!

I believe Rayners Lane is actually a listed structure. I'd have to ask my colleague at work who would be responsible for allowing it!
I would expect the old chestnut of the signalling system would be the answer to be honest.

how does the listed structure prevent a dmi from being installed?
yes i realise the system is ancient, but that does not explain why the information is able to be displayed right up to south harrow!

I could be disastrously wrong about this, but the last I heard Rayners Lane-Uxbridge was still controlled by Rayners Lane signal box. At any rate I'm pretty sure the rest of the Picc is controlled centrally from Earl's Court, no? Which could well have something to do with it I think? Clarification would be welcome, it's hard to keep up to date with exactly what's been modified and when!  |

Anyway the outskirts of the Met are definitely still controlled by signal cabins (well, I'm quite sure they are in some places anyway, I'm sure there's still a working signal cabin at Amersham isn't there?) and I should imagine that this complicates things a bit. The rest of the Met is under relatively modern, centralised control. Anyway, out on the outskirts, the met is timetable driven, not headway driven and people tend to use and stick to the timetables. Changes are gonna come, I think, but up til now people have made do with timetables. The met has for a long time, I think, been well described as more like a conventional railway with a short underground bit. Obviously the Metropolitan Railway was the first underground railway in the world, but it retained a lot of its original features Oh and there's Chiltern to consider, so you'd have to find a way of having both. This may not actually be very hard and Chiltern stations do have digital displays in plenty of locations, but it's another complication I would have thought? |

Firstly, I'll dispute the assertion that the signalling on the Bakerloo is 'ancient'. It is mainly of 1980s vintage which is not old in railway terms. Certainly the line north of Queens Park was resignalled in 1988 by British Rail replacing the unique LMS New Lines signalling dating from the 1930s. The Bakerloo (south of Queens Park) is controlled by the signal centre at Baker Street. North of Queens Park, it is controlled by Wembley Mainline SCC (Network Rail). Regarding the Met, the line from Northwick Park south is also controlled centrally by one signal centre at Baker Street. Beyond Northwick Park, the line is controlled by four separate signal boxes. These are: - Harrow on the Hill (Harrow South Junction - Moor Park)
- Rickmansworth (Watford South Junction - Chorleywood/Watford)
- Amersham (Chalfont & Latimer - Mantles Wood/Chesham)
- Rayners Lane (Rayners Lane - Uxbridge)
I'm pretty sure the extemities of the Met isn't the only part of the network without working DMIs/DVAs. I don't think the east end of the District has working DMIs/DVA. |

surprised this hasnt been mentioned before but moor park has recieved dmi's for all four platforms which actually show when the next trains are arriving! so this brings me back to my original question, its possible at moor park so why not at least for the stations south of it? can anyone shed light on when these were installed?

Most of the Central line doesn't have platform DVA's, although all stations have DMI's.

We stayed in Uxbridge last October for a week & I noticed this. Both with the Met & Piccadilly trains, too.
However, every train we caught to or from there had at least a digital info board in working order in every carriage and most had announcements, too, even if it was simply 'This train is a Metropolitan Line Service to Baker Street, where this train will then terminate.'
I wonder if it's because there aren't a great variety of short workings on the branch, so, unless it's one of those suddenly forced on them, there's no need to put it up on the platforms, because it's only going to be Baker Street, Aldgate or Cockfosters in nearly every case? Equally, how many tourists would need that info, compared to the number who would in the central area?
The rest of us, meantime, also have enough space on those platforms to be able to safely read what's on the front of the incoming train-which I would hesitate to try as a modus operandi of finding out where the next one's going at Russell Square/Bank etc!
All of which makes me suspect the lack of these might be solely down to an unwillingness to shell out, install and maintain what there doesn't seem to be much call for; equally, have you tried bringing it up with TfL and see what the official response is? Without being facetious, you really could be the first person that's asked them why this is the case, instead of just accepting it. |

I'll second that. As a regular user of the 0703 Croxley to Aldgate, it seems to usually turn up at some point between 0659 and 0706, with a corresponding long or short wait at HotH, where everyone piles off the Aldgate all stations from Uxbridge and does the Harrow dash to get on it.

Why? Is the one coming down from Croxley semi-fast? Hardly seems worth the bother if you ask me! |

Yep - then fast HotH to Finchley Road. Maybe they don't like the squish after Wembley Park? There's a load do the dash every morning, so it must save time.

Yes, I'd forgotten they skip Wembley Park as well. I suppose it saves a few minutes. I guess lots of people have their little routine commutes - you can probably get quite slick. Well I suppose it can give you five more minutes in bed/a five minute buffer/five minutes to have a tea when you arrive at the office.

As a former Station Supervisor at Croxley it always seemed the case that you could set your watch by the arrival of particular passengers. These were the one's who were going to catch the semi-fasts. |

Moor park is controlled by the Rickmansworth cabin, as dot matrix indicators are provided there I cannot see why they could not also be fitted at Croxley, Watford and Rickmansworth, also in the Rickmansworth cabin area.
