Hi all,
Was going to Heathrow this evening (around 6ish) and was on the eastbound platform at Southfields. The DMI said the next train would be a City via Victoria, but when it came, it was an Edgware Road one.
This continued on the whole of the Wimbledon branch, this is what the DMI's were stating our Edgware Road train as:
East Putney: Not Stopping
Putney Bridge: Barking
Parsons Green, Fulham Broadway, West Brompton and Earl's Court: Dagenham East
Why was this?
Also, at Barons Court, I saw a District Line train going to Mansion House which seemed odd
And at Acton Town, I was in a Picadilly Line train for Heathrow at platform 2 and another Piccadilly Line train bound for Uxbridge came at platform 1 which I found a bit unusual.
When the train arrived at p1, an announcement was made which stated that passengers for Ealing Broadway are reccommended to take the Uxbridge Picc train and change at Ealing Common for local bus services because there would not be another District Line train to Ealing Bdwy for atleast another 15 mins!
What happened?
Thanks, Uzair

I wasn't working last night, but I'll have a go at answering yer questions..... The DMI said the next train would be a City via Victoria, but when it came, it was an Edgware Road one. That's quite common - first of all, your train most likely got to Wimbledon 'out of turn', it then would have left 'back in turn' but for some reason I've yet to fathom out in 4 years as a District driver, it still picks up the TD (Train Description) in the same order as trains arrive at Wimbledon - hope that makes sense? This continued on the whole of the Wimbledon branch, this is what the DMI's were stating our Edgware Road train as: East Putney: Not Stopping Putney Bridge: Barking Parsons Green, Fulham Broadway, West Brompton and Earl's Court: Dagenham East Why was this? Again this happens quite often - LU will take the TD from Network Rail, so if the next train was expected to be a Dagenham East (for example) that's what the 'City via Victoria' will become. Essentially, it all boils down to 60's technology which is now out of date and not up to todays expectations of information provision. Also, at Barons Court, I saw a District Line train going to Mansion House which seemed odd That isn't the slightest bit odd at all - all late running Tower Hill trains go round at Mansion House and it happens so often I might have to ask for re-training before I next go into Tower Hill bay! ;D ;D And at Acton Town, I was in a Picadilly Line train for Heathrow at platform 2 and another Piccadilly Line train bound for Uxbridge came at platform 1 which I found a bit unusual. Again, there is absolutely nothing unusual about that at all. When the train arrived at p1, an announcement was made which stated that passengers for Ealing Broadway are reccommended to take the Uxbridge Picc train and change at Ealing Common for local bus services because there would not be another District Line train to Ealing Bdwy for atleast another 15 mins! What happened? Now that I can't answer, not being at work, but it could have been something as simple as a train cancelled or perhaps as a result of some incident, of which there are far too many possibilities to list - station staff should have given a reason if they knew why. |

the TD problem on the wimbo line is due to NR staff not uploading the timetables onto the WARS system so when the train is in putney bridge platform the programme machine or sig op depends what mode they are in changes the TD to the correct one

Putney Bridge does not have dot matrix indicators or train describers they are called veids in our neck of the woods.
If the train runs up from Wimbledon out of turn the veids are corrected as the train runs through Putney's east bound platform. The correction is done from the IMR just outside the station and can be done from the signal operator at Earls Court if they have the frame. This causes no end of complaints from customers.
I believe (someone may correct me) that there is a roll of what looks like cooking foil in the IMR at Putney Bridge with little holes in. As it turns round each hole indicates the correct train destination and also works the signals. Signal staff come down a couple of times a week in the dead of night to programme the machine.

no they are called programme machines the little thing in the IMR and theres 3 of them one of the e/b and 1 for the w/b and one to do the timing they are called S1 S2 T1 the programme machines will only put the right T/D up if the machine is in programme only which the signal ops like that is why you see us quite a few times during the day and every time the timetable changes the roll is changed of a night usually a Fri Night / Sat Morning they are suppose to rewind themselves at 3am put putney will not if the correct day is not done properly via relays aetearlscourt.fotopic.net/p15106337.html that link is a programme machine at earls court the ones at putney bridge are no different the VEIDS are actually just the display in the supervisor office and also the small dot matrix screen infront of the stairs (where the 3 seperate old type dot matix signs were) this is piggy backed off the T/D system and this is why they show the same info. the signal op always has control of the frame except for emergencys or during engineering hours when we ask permission to release the frame into our control by removing the air from the frame all the programme machine roll reading from left to right is as follows TIME ROUTE LIGHT HOLE T/D (not all machines have this) TRAIN NUMBER it is in binary format not HEX as you see it does not look like cooking foil more like the old drum (automatic) pianos from years back beleive it or not it is very complex and the next picture will show the Earls Court Card room this is all the cards to operate the 10 machines there. Putney Bridge works from relays as it was the first site on the district to have programme machines but the principles are exactly the same aetearlscourt.fotopic.net/p15106342.html |

Provided the westbound numbers are correct on the programme machine at Putney Bridge and trains are in turn this will give information to the WARS computer i.e. train E075 for an Edgware Road east bound trip or Train C030 for a City bound train. If there is out of turn working then the signal operator on the Hammersmith Desk will input the code E for Edgware Road, C for city bound H for High Street Ken and so on then the train number 075 or 127. This should ensure the trains leave with there correct TD from Wimbledon. But this depends on the information being correct and inputted to the WARS and also if the information is inputted in the first place.
Kind Request from me to all you lovely train drivers if your train description is not correct at Putney Bridge or Parson Green could you please tell the signal person on the Hammersmith Desk before leaving Parson Green. Many Thanks.
MOD EDIT: Auto number removed - The number for the Hammersmith signalman can be found in the duty books.
