For those interested, the long running problem with sunlight affecting the OPO monitors at Oakwood is almost resolved. The large mirror and single CCTV screen that replace the former 2 CCTV screens and smaller mirror were brought into service this morning... whereupon it was promptly discovered that the mirror was angled incorrectly, drivers therefore couldn't see the length of the train, and we had to man the platform all day. *groan!*

Let us hope Harlesden N/B gets the same treatment.

Did they get rid of those boxes for the CCTV that are obstructing the 'Green Stripe' stopping mark and if not any ideas when?

I think the "1 big mirror one screen" opo's are better than the traditional 3 or 4 screen and small mirror ones

DOC Depends which you mean - the previous empty monitor casing has been removed, and the old CCTV box has gone - I'm unsure if the new one is sited differently enough to maake a difference.

It was the empty monitor casings that I meant. Was a bit of a pain for the trainee to stop with the green stripe in the cab door window when it was obstructed!

Re: OP. Excuse possibly a naive comment, but shouldn't the mirror view have been physically tested before the job was "signed off" as being up to spec? I assume it was done in non-traffic hours, hence in the dark at this time of year? A person on the platform with a torch and a walkie-talkie with a 100m range communicating with the "driver" should have been able to confirm the correct optical alignment of the mirror after installation in a matter of a few minutes. Paradoxically, such a test might have been made even easier in the dark? Won't even dare to comment on it being apparently a long-outstanding problem. Do wonder if the platform mirrors and associated equipment essential to safe train operation are the responsibility of a privatized, hived-off company..... Anyone care to enlighten me please? cheers.

OPO is outsourced, has been for years even before InfraCos and PPP. OPO monitors and mirrors were the responsibility of more than one contractor, all the new stuff, grey cabinets etc was installed by WCL these days known as CTS and the old OPO (red housings etc) was maintained by Datel Comms. LUL Comms lost the maintenance and installation contracts way back circa 1995. It was one of the reasons I moved from LUL Comms to Picc Line Signals in 1996!

railtechnician and undergroundgal, Thank you both for your responses immediately above. I really hesitated before hitting enter on my own OP query, in case it was considered inappropriate or political etc.... whereas I though my enquiry was justified out of basic common sense, which also could be "hostile" suggesting I knew better than those in authority. If I could conclude the point - without risk of being flamed - I'm self-admitted here at DD for being a conservative with a small "c", but increasingly believe that breaking up the essential Social and Service Industries and Utilities (as with privatisation etc) is Not A Good Thing. My sympathies to all LU staff (and under whatever post-privatisation former LU staff wearing their new hats) that you have all these tiers of different corporate management and legal teams adding to the cost, and dare I suggest - reducing the motivation - towards running a safe, efficient and essential Public Service, that you have voluntarily chosen as your careers to serve. Apart from my points raised, reading the posts here suggests there are more practical Operational points relevant to Oakwood that just have not been taken into account? And concluding: Wishing Kind Regards to Tubeboy at: « Reply #1 on Nov 7, 2007, 8:08pm », I assume your wishes are that Harlesden N/B justifies similar attention to an operational problem there, but perhaps a Better Solution than Oakwood seems to have received? Cheers, all.

Unfortunately I'm rather limited in that I've only ever worked under PPP so I'm unsure what the direct experience was for people before it - I also didn't even live in London. Whilst in an ideal world there would hopefully not be the split, the biggest single problem in the whole mess is government, who are willing to do pretty much anything so long as the expense is off their books.

PPP means, of course, that nobody need ever take the buck for anything. It's always so-and-so, who blames it on such-and-such contractors, etc etc etc. In the end, the passenger/rate payer ends up paying extra because of it.

The new system was checked out with the first train and was found not to be right, so was not brought into use. OPO has to be checked with a train present and it is really hard to get a train in a platform during engineering hours without booking weeks in advance.

Yes and this in my opinion is one of the grestest flaws in the SABRE system. A good engineering access coordinator would have the knowledge and understanding to integrate various works and to ask pertinent questions reguarding requirements. If the works were properly planned from the outset there would be a lot less wasted time and money. As it is works have to be planned months in advance unless they are emergency works and the local contract planners, i.e. SOMs and equivalent grades in all contract firms, have got into the habit of 'blanket' planning which is as useful from an access coordination point as no planning at all but it means that they have a legitimate SABRE number to generally work at many more locations than they intend to. SABRE is a good idea but the implementation leaves a lot to be desired. Brian

couldn't they have just stabled a train in the platform overnight or did they need access to the track?

Or arrange for the power to be turned on half an hour early, have a train brought into the platform, checked everything, tweak if required?
Certainly, if I was going to sign an invoice for a contractor doing work, I'd want to check it was to specification before handing over oodles of cash.

The thing is the person who is responsible for the work on LU's side isn't the one controlling the cash, and money transfers between LU and the Infracos all the time. If something isn't right, it gets added to a snagging list and until the snag list is dealt with the project can't be closed out, thus delaying final payment.
Also, the scenario you describe requires early current (extra money), shorter engineering hours (less time and greater risk of overrun = extra money in fines), a train to be prepped early, train crew or test crew (more money for someone to come in early on overtime or even more if test crew have to be booked) etc etc.
Simply, the most eonomic way is to let the first train do the testing and go from there. Money definately won't change hands if it isn't commissioned though.

Sorry Tom but I can't help saying that ,while I acknowledge and understand the case that you make, what is missing, and has been missing for some years probably since devolution, is proper and effective co-ordination. As far as projects being closed out and snagging goes I can think of dozens of outsourced projects in the years prior to PPP that were never checked properly. The tunnel lighting was one such project where corners were cut such as leaving the old lead cables feeding through ducts and jointing to them at some stations because it was easier than running in the new pyros! Undercroft lighting in at least one location I can think of was never properly completed but the contractor was paid off and moved on.

I thought that a few T'Ops were on "night shifts" whereby they drove the last train then had a 4 hour break or something before the first train? Couldn't they just take a train out earlier? Ad for the engineerign work, schedule slightly less that day, and surely it can't cost that much to turn the leccy on a bit earlier.

I agree, but I think it depends on who the contractors are. One or two spring to mind very quickly here!

Ad for the engineerign work, schedule slightly less that day, and surely it can't cost that much to turn the leccy on a bit earlier. Whilst there are night T/Ops, they may not be in the right place to do the move - it all depends on the duty. On the engineering work front, there's so much going on these days that to shorten engineering hours would be absolute madness! If you shorten engineering hours, contractors are within their rights to start making claims for lost time (as they still have to pay their staff for the full shift, even if they get less than the full shift's work out of them) and with the number of contractors involved it can get very expensive indeed. Quite simply, the cost/benefit ratio doesn't add up.

Hmm. Again, why not outstable a train to the platform overnight? As for staff pay, if their shift is 10 hours or whatever sure pay them 10 hours - but if they're sent home after 9 hours, why should they get 10 hours pay?

Phew! Grateful to you all for your views and posts since my #6 - and the OP as well. Such a lot of opinions and comments re: just ONE location and "engineering"/"operational"/"safety critical" issue ! I think I have two main reactions to what I'm reading and understanding here: ONE That so many experienced and knowledgable professionals are spending their valuable spare time in contributing to this thread; TWO That clearly the bl***ing obvious solution to the problem is not an option. I've initially considered all points mentioned in the above replies, and noted the restraints and constraints referred to. FWIW, I'd volunteer another half-hour or so contributing to this thread if anyone is interested. Please PM me if you want to hear IMHO, or just blow the whistle on what really goes on I give you my word I'm not an undercover investigative journalist ;D I'm a mature, amateur, LU Enthusiast, with special interests in operational and technical matters, and just got a personal feeling the OP here is the tip of an Iceberg....

As for staff pay, if their shift is 10 hours or whatever sure pay them 10 hours - but if they're sent home after 9 hours, why should they get 10 hours pay? It all depends upon the contractor! Many subcontractors once had a policy of expecting staff to turn up for night duty at their own expense but only paying them if they actually worked the shift or for the number of hours that they did work. In some cases this meant that if too many higher grade staff were on hand they had the choice to go home without pay or work at a lower rate commensurate with the available work. This was prevalent amongst track subcontractors just as working both the night and the following day shift was and at times when mandatory training was due to work the night before the day training shift too! There was little job security and little loyalty either ! As far as the main contractors are concerned staff are paid per shift whether there is work to do or not. Generally the maximum working time in any night shift is 4 hours but when possessions and / or engineering trains are required it can take so long to make the necessary protection arrangements that actual working time can be as little as one hour. Running trains on current or at all in engineering hours is not the simple task some may think it is! Protection is often delayed by line controllers moving trains about to balance stock, duty depot managers moving trains about to ensure they are on the correct tracks for next day's service, carriage cleaners in sidings requiring current to remain on until they have finished their cleaning, late running as a result of earlier failures and other delaying incidents, the business of making the necessary isolations, disconnections etc before being able to take a possession, and unrelated and uncoordinated other work (SABRE failure) in the vicinity. The list is not exhaustive but there are so many ways that a job will be cancelled and the staff will be sent home! It is not the fault of the staff if they attend for duty and are not given work to do! The lack of contingency in a situation where a job is cancelled is a management failing rather than a staff failing. However, goodwill is a key factor in railway work and as the management know to their cost there needs to be give and take in the system for it to work at all. Loyalty and morale have always been the mainstay of the engineering departments and even though they are private companies today that same dedication to the job exists amongst the majority of the 'family' who take the rough along with the smooth!

Hmm. Again, why not outstable a train to the platform overnight? For starters, all trains have to be prepped by a depot fitter once in every 24 hour period - an that's signed off on the defect book in each cab - no train prep equals no train in passenger service. The easy way round that though is to take an early evening stabler that's already been prepped and use that. Now you need to get that train in position. This will require a spare driver or a test train driver - as the move would be planned in advance, you can't rely on a spare being available so you need to have a test train driver. The same will apply when the train is put back in the depot prior to the service starting up. Tying up a test train driver like this is a complete waste, to be honest - not to mention the cost of his/her wages. Remember it's only a mirror (and monitor, though that can be adjusted without a train present)! Because this train is required after the last train has passed through, and needs to moved before the first train of the day, you have the aforementioned issues with the extension of traction current times. Now I don't know the Oakwood area, but if it's a tunnel section........well, track inspections have to done within certain time frames etc - a train in the way would pose an issue. Then there's less obvious stuff such as adverts opposite platforms. Again I don't know Oakwood, but such things can only be dealt with at night in engineering hours and without trains being present. So in essence, it's very easy to say bung a train there overnight', but it's all a bit much just for a mirror. The easier answer by far is that the contractors wait for the first train - but then again if they're done by say 0300, it's a waste to have them hanging around doing nothing for 2 hours or so till the first train turns up. I don't think there's really a right or wrong solution to this.

Oakwood is above ground and directly next to Cockfosters depot - trains can enter the depot from either platform at Oakwood as well as Cockfosters.

Yes and an added complication doing anything that will or may involve trains and tracks from Wood Green to Cockfosters is that the local signalling computers usually have to be checked and reset. It's no fun doing a rerailing, tamping or other such job in that area especially when the computers don't want to play nicely. Many times I found myself trying to get the computers up and current timetable reloaded after a night's work with just minutes to spare before the first train arrived. We always used to try and give ourselves an extra 20 or 30 minutes to allow for computer problems so that cut the working time down sometimes to less than 3 hours.

What an intriguing thread has developed.
A bit suspect as being the mere tip of an iceberg.
undergroundgal, shame I'd get done for numerous civil and criminal prosecutions if I offered to lend you a couple of spanner and socket sets, and adjustable wrenches, so you could actually get the problem sorted properly.
Presumably, like signal heads, the mirror supports are capable of accurate adjustment in situ.
So I'd better not offer, then :-(
Is the mirror realigned correctly yet, since your OP of Nov 7th?
Cheers.
:-)

Cheers. :-) Yes, they managed to get it sorted for SOT the next morning, thankfully - I even stopped off on the way to Arnos to check since I was spare again and didn't see the point of going there and then having to double back to Oakwood. But all was well! They have similar mirrors put in at Arnos as well - due to the sunken position of the platforms there was never quite as much problem with sunlight there, although (unconfirmed) rumour now has it that since the replacement mirror was brought in, sunlight's been affecting the eastbound on platform 1. I'm going to hope that's an exaggeration or misunderstanding...!
