Thanks for pointing it out, i notice they have added more (correct) stations on the Met.
Are there plans to extend this to other lines and stations and if so when.
Thanks.

I'd be interested to know where its getting its information from, as Ive just seen a train heading for Willesden Green Siding. Not that I'm complaining, mind |

Theres also a met in farringdon sidings, apparently.
And an uxbridge train has just left Aldgate East. Apparently the Met to Barking is back on!

Oh dear this thread is turning into a comedy show! ;D Just checked the link for the charing cross jubilee, and all it says is 'there is currently no details for this platform' So should I take it as if whoever are the people behind this system, one of them is a regular visitor of this forum! ;D |

It gets its information from a mixture of sources. On the Jubilee and Met/H&C for example, between Stanmore/Wembley Park and Green Park/Aldgate it gets information from the signalling computer system at Baker Street.
The system-wide Trackernet also has a hand in supplying information. This in turn gets fed by signalling computers and the Connect radio system.
It's a complex web and occasionally it throws up some oddities based on what it thinks is happening. The quirk about sidings trains is it taking "raw" information, and shows where some additional tweaking is still needed.
But then again, so what if we tell people there is a train in Farringdon sidings waiting to come out. At least it's on its way and is going to be a nice empty train for those at Farringdon ;D
Use of the same information also now supplies dot matrix displays at various locations particularly in the Circle Line central area. The new "Next xx train within xx minutes" displays are fed by the same information. This too can get a bit tangled, based on what it thinks it can see.
The recent King's Cross service on the weekend has quite often seen trains forecast at Baker Street as "Next Circle Line within 20 minutes" when in fact there is no Circle running, and there is a King's Cross train in the platform. This is where the system detects a non-Circle train in the platform, and searches for the next train on Trackernet that "looks like" a Circle - i.e. it has been routed from Gloucester Road to High Street Ken.

I guess it will be a while before stations on the Uxbridge branch show destinations like Aldgate and Cockfosters instead of Metropolitan Train and Piccadilly Train.

When I looked on there an 'Unknown' train was 1 minute from Farringdon (currently in Farringdon Sidings) and didn't ever get any closer  Also it was evidentally expected to be heading up the Met main as it was also appearing at Baker Street at platform 2... |

An 'unknown' train that is in Farringdon sidings will appear on Baker Street platform 6 as well as platform 2. As it is unknown, the live departure boards do not know what way it is going. It would be unusual for a train in Farringdon sidings to go up the Met Main Line, as Farringdon sidings are not long enough for A stock.

Would an empty train from Hammersmith to Neasden (or vice versa) in traffic hours be reversed in Farringdon sidings?

This past week has seen a road-railer type thing stabled on one of the sidings at Farringdon. This means there is a "train-type" indication there during the day at a time there wouldn't normally be a train.
Although as far as the signalling computer is concerned there is no data attached to this train, it would not surprise me to learn that it has been forecast by the Trackernet and subsequently the online departure boards.
Clearly there are some tweaks required, but I think many of these quirks have occured due to the system being set up to give "too much information." The setup is such that if we were planning to bring a service train from, say, Farringdon sidings, the information system will attempt to forecast it in advance, which I suppose would be a bonus. However, when there is simply an extra stabled train in a siding, it's not ideal to forecast it as anything.
For all it's failings, you have to agree that the various systems certainly give the customer a lot more information than they used to have - albeit most of them only seeing the train lists from their home PC - some distance from the platform where the information would be of actual use.

Agreed! The information at places like Moor Park leaves an awful lot to be desired... It would be great if this info was available on the tfl wap site... |

Yes, this area even has problems being correctly shown on Trackernet. There's less train describer equipment to feed information systems, and it ends up being a guessing game based on where the train has come from. For example, it predicts northbound Amershams simply when a train is seen to leave Harrow on the main lines, and predicts Chilterns based on where it has entered the area. Trains ex-Watford are "generally" guessed to be Baker Street, but it often plays safe by saying "Metropolitan Train." But again, at least you know a train is on its way, and is likely to go to Harrow at least. Before, it was in the lap of the gods ;D EDIT: Although rather worrying, after checking it just now, it forecasts an Up Chiltern train expected in 16 mins at Moor Park southbound. Even when they're running - which they're not today - you'd have some difficulty boarding it ;D |

I notice that the boards for the westbound platforms on the Uxbridge branch are very particular about where the approaching train is heading.

When do Piccies that are in the siding at Rayners actually register as the next train in sequence? I know that it takes more than one minute for the t/op to walk the length of the train; and IIRC off-peak Rayners reversers stand down for 20 minutes before making another eastbound trip.

Post by suncloud on Feb 17, 2009 8:55:04 GMT
I've seen Rayner's Trains leave East from the Westbound without using the siding. Presumably in theory a train in the siding could move in from the siding to the westbound platform and continue east, and the departure boards aren't clever enough to be have a guess...

The software does not have access to the timetable, therefore as said in my previous posts, a lot is done on "educated" guesswork.
It would be interesting to see how the train in Rayners Lane siding started off on the prediction. One it was detected there, was it based on the average booked reversing time. Was it always predicted as "1 minute" until it moved into the platform. Or did it become "1 minute" once the software detected the shunt signal from the siding had cleared.
The E/B & W/B matter could possibly be the train being en-route to the siding, and thus being "still on the westbound" but also predicted for the eastbound if you see what I mean.
Without some positive identifcation of what it is showing compared to what is happening on the ground, you are unlikely to get fully to the bottom of all of these quirks. But as I said, at least it now gives you a lot more than you had before.
