Why can't the Picc terminate southbound at Wood Green?
It seems like the picc is going to be out of action for a long time
around the kings X area unfortunately. Ok , but surely that doesn't mean a huge stretch has to be closed all the way from Hyde Park to Arnos Grove? Surely it could at least run south as far as wood green and reverse in the siding there? That would at least cut out 50% of the unpleasent replacement bus service B. B2003 |
Why can't the Picc terminate southbound at Wood Green?
Trains can only reverse north to south via W.G Sdgs. Once trains are in
the sdg they can only be routed on to the Southbound platform. Also a train in the southbound platform can only be routed back in the sdgs |

If it is not in passenger service I hasten to add!!

ups.com... Is this an operational restriction or a physical one? If its the former surely some special operational plan could be put into force? It's both. The signalling was not designed to allow it to happen, so you could only do it by working (and securing) the points manually. The diagram below shows the area [1]. To reverse from south-to-north the following would have to happen:- 1. Train runs in to southbound platform (no problem) 2. PG4 clear for shunt in to siding (no problem) 3. 6 points reversed/secured and train authorized out of siding (past PG10 at danger) (problem - no protection from a train approaching from the south - PG1 is too close to the platform to do this, all other signals before that are automatic). 4. 6 points normalized/unsecured and PG2 cleared 6 ---------------------------------------------------------------------------------------------------------------- N/B to Cockfosters |o PG1 ############## |oo PG2/3 \ PG10 o| -------------------------------------- ############## |oPG4 / ---------------------------------------------------------------------------------------------------------------- S/B from Cockfosters PG11o| 7 PG12co| PG12bo| PG12ao| The problems basically are securing the points and authorizing the train out of the siding. It could well require the power to be taken off (further complicated as you might have to involve the sections for both directions because the siding is in the middle, plus the gaps with the next section to the north happen to be at 6 points), and would take a lot of time. There is a fixed red lamp at the southern end of the northbound platform, however it probably doesn't have a trainstop, so some kind of additional protection would be necessary. I suppose the problem of northbound trains could be dealt with by holding the Turnpike Lane stating signal at danger and renumbering it as an "X" signal, but then you lose the ability to transfer trains from Northfields to Cockfosters via the northbound line (has this been happening, or vice versa?) or to run (engineers?) trains out of the bomb site. [1] Layout is correct, but doing it from memory so certain numbers might be wrong. Also, referring to north and south for convenience - I'm sure someone would have be along to remind everyone that the Picc is considered to run from east to west! |

If it did, one could stretch the rules and use it to lock the northbound-to-siding crossover. |

That would at least cut out 50% of the unpleasent replacement bus service B. A few changes to WAGN services would help - Ally Pally (a 10 minute walk or a couple of minutes on the bus fom Wood Green) to Finsbury Park and Kings x/Moorgate is every 10 minutes in the mornings. But the trains are becoming increasingly packed; stopping a few fast trains there and selected affected stations on route especially at non-peak times (especially weekends) would help.... surely it can't be that difficult to do? It does seem to me that the other transport links from town to that area are operating with no concessions to the current closures. The buses (29, N29) which provide links to town form that area are doing their best but it's not enough. |

Does sound a bit of a mare. Though I'm surprised the siding isn't set up to allow this as this isn't the first time the line has been closed from Hyde park to arnos grove and I'm sure it won't be the last so it would certainly add a bit of extra flexibility to the service not to mention making commuters lives a bit easier.

If that is the case, why no Rayner's Lane to Uxbridge service then? This has been rehearsed here before... Because it's being provided by the Met., and we don't have the capacity to turn that many trains at Acton so it's a basic 10 min ACT - RLN service in the KISS fashion. If they start adding additional clever bits it will, as sure as eggs is eggs, fall apart in short order due to lack of trains/drivers/paths. At the moment, the staffing of these trains is still being done on the hoof and doesn't have the benefit of utilising staff right to their booking off time that you get from pre-planning the service as is normal. We might have loads of trains sat about but all the drivers are in the wrong places too - Arnos being the bigger depot have more drivers than Acton, we're having to be taken to the other end of the line to provide cover. We're also double ending the HPC reversers to get them tipped out and reversed in 5 minutes and providing the AGR - CFS shuttles. So there isn't a huge surplus of staff there either... -- Steve Fitzgerald has now left the building. You will find him in London's Docklands, E16, UK (please use the reply to address for email) |

No - regrettably the Picc Line is a "trunk route" between key depot locations like Ruislip, Acton and Lillie Bridge and other tube lines like the Northern and Victoria. The key crossovers and junctions are at Kings Cross and Finsbury Park.

My point was that the only way of providing more trains would be to stop some of the GN Outers. They are all made up of four car units of classes 317 and 365. Obviously a four car train could stop but is there room for eight cars? The GN Inners use class 313 three car units, so the trains are three or six cars.

Ah, but the extra trains you were talking about stopping are sometimes 8 cars in length (and maybe 12?), so they might not fit in a platform if it's only designed for 6-car trains (like the surburban platforms at Kings Cross).

I went in to work today for my normal duty (1748) to find they'd all been changed around and I wasn't booking on till 2000. Needless to say, I was extremely unhappy sitting there for 3 hours when I had better things to do - and I told Maxwell (formerly of your Parish, I gather!) just what I thought about them not warning us in advance. The HPC thing seems to be working quite well with two pairs of drivers taking the trains from the incoming operator and reversing them east to west in very short order and handing them back. We do seem to be able to maintain the 5 minute Heathrow without too much trouble this way. I quite enjoyed doing it last night too. We're using a mix of Arnos and Acton DMTs currently, although from what I can see he/she's just there to log the trains and who reverses them. Drivers are sorting themselves out as to which trains we do and who goes at which end. I'm booked to do it again tomorrow though, so I'm looking forward to that one. I gather 'schedules' are coming up with a properly rostered up temporary timetable which does suggest they're expecting the worst. And we still haven't got our chocolates :-( -- Steve Fitzgerald has now left the building. You will find him in London's Docklands, E16, UK (please use the reply to address for email) |
