I am sure that when I first got interested in the underground (the '70's), that derailments were almost unheard of. Is that just an impression, or have they really become more commonplace in recent years?

How many staff would be needed Simon to safely and quickly evacuate say just that one train with circa 600 customers on? 2 at the train, 2 at the platform edge/ramp and how many along the track.... It took me 1hr 15mins to detrain 748 people through the rear cab of a train into the one behind with me and the driver of the other train to assist them. Detrainment time is a function of the exit speed from the train.

Detraiments using a train are quicker than one that involves walking on the track - small managable groups. I helped with a 3 train detrainment, that were lightly loaded (approx 200 in total) that took 50 mins, but then we did have loads of staff and a chorus of BTP officers.
Would I be right in thinking that under new rule books, detrainments via another train don't require the input of a Supervisor anymore (not that they'd probably be any good anyway).

Detrainment time is a function of the exit speed from the train. Exiting a train through the M door onto the track, I guess you would get a maximum throughput of 3 pax per minute, perhaps 4 if your lucky. I imagine it will also depend on who you have to detrain - young, fit, cooperative people will be far easier than frightened little old ladies and obnoxious, overweight and unfit people. For a transfer from one train to another, I guess it will be a bit quicker, perhaps up to 5 or 6 pax/minute. Using figures of 3 pax/minute and 300 pax/train (TfL's websites quotes a seating capacity of 272, and total capacity of 1652 for an 8-car 1992 stock train), this works out that it would take about 100 minutes, or just over an hour and a half to detrain onto the track. This excludes any time needed to walk along the track to the nearest station. Passengers with disabilities will also require more time - I don't imagine that even if a wheelchair could fit through the J and M doors, which I doubt (does anyone know? what about the 2009 and S stocks?), it would make much headway on the track.

Why would the person be left in their wheelchair? I thought they had to be carried out? Also one must realise in those situations that saving another life is far more important than taking various bits of metal with one person to preserve thir dignity.

Thats quick work if they achieve that .... The TfL site says the RAIB handed the site back to them at 5:30pm. I expect the ERU to be able to re-rail the train without too much of a fuss, say 3 hours as a pure guess. That would leave them about 15½ hours to repair any damage to the track and tunnel. I presume that a fair proportion of the assessment of what damage has been and what consequential repairs are needed could have been carried out in parallel with the safety investigation(s) and re-railing the train. This would enable the necessary materials, staff and equipment to be in position to start once the train if off-site. I was sat at home, listening to the radio. You arranged your shifts well then!

It does sound rather crude, but yes, they would either be dragged or carried out, or left there.

Indeed, I don't think they would be left in their wheelchair under most circumstances. However, if they need to be carried then someone needs to carry them (who then isn't able to assist other passengers), and therefore they will take longer to get out of the train than an able-bodied person. Also everyone in a wheelchair is different and has everyone different mobility - a person with both legs in plaster will have more restricted movement than someone with weak legs who can walk for short distances/periods of time for example.

Indeed - persons who are unable to de-train themselves will be assisted, or left on the train, depending on the circumstances at the time. As for Would I be right in thinking that under new rule books, detrainments via another train don't require the input of a Supervisor anymore (not that they'd probably be any good anyway). Rule book 4 refers - if a detrainment is authorised from cab to cab (ie, one train behind another), then the train operators can do this without any further assistance. If a wrong direction movement is then needed though, then we obviously need an 'operating official' - but the detrainment can still happen prior to their arrival. All other detainments (including to an assisting train on an adjacent line) must have a 'detrainment supervisor' present first. The only exception of course is an emergency detrainment - that is where the train operator deems it necessary and authorises him/her self (ie, fire).

Detrainment of Deep Level passengers.
The detrainment of pasengers from a train in a deep level single line tunnel is obviously more complicated than detrainment elsewhere and there is the added difficulty of the current rails along the escape route. Detraining from a 'normal' accident (ie: Kensal Green ) is so much easier for many of the passengers when many can walk to the nearest Supermarket to recover. Unfortunately this is one of the risks in deciding to travel by deep level tube. Even in a supposed Terrorist Attack the fact that you are still there and able suffer a panic attack is a good sign !

This looks rather interesting www.workersliberty.org/node/8819Here it is copy + pasted. Central Line derailment: Management cut corners on safety Submitted on 6 July, 2007 - 08:52 :: Central line | LT Health & safety | Metronet Yesterday's derailment on the Central line was in the same place as another incident just six weeks ago. On May 21, a train struck a P-way storage bin left by the track, and was lucky not to derail. Union health & safety reps complained to management and demanded an investigation. This was not the first time that union reps had complained about lineside scrap in this area. Six weeks later, no investigation, no action ... and the inevitable derailment. This case shows clearly why union health & safety reps should have the right not just to complain but to order investigations and action. We obviously can't trust management to do so! The apparent negligence of Metronet defies belief. This time, a bale of tarpaulin came away from a licensed storage facility in a cross passage in the tunnel between Bethnal Green and Mile End. Which begs the questions: Was the storage facility properly secured? Was it even fit to be licensed for storage in the first place? But we shouldn't allow LUL management to pass the buck entirely to Metronet. It is responsible for ensuring the safety of its own employees, in this case the driver. Slagging off Metronet, although well-justified, is becoming a convenient excuse for LUL. And the fact is that it is the Public-Private Partnership (PPP) set-up that causes these appallling incidents, and LUL management continually urge us to "make it work" rather than urge the government to scrap it and reintegrate the Tube system. Meanwhile, TfL big cheese Howard Collins appeared to play down the incident by saying that it was the first derailment of a passenger train for a number of years. He had to be careful to use the word 'passenger', because there have been several depot derailments; and the "number of years" he referred to is the four since the Chancery Lane crash - not exactly a era, eh? It was fortunate that there were not more serious injuries - or worse - but for the hundreds of people on the train, and on the train stuck behind it in the pipe, it was a horrendous experience. With the country on critical terror alert, many passengers were terrified that they had been bombed. Hundreds of thousands of people have had their travel disrupted, and Tube workers have been landed with extra workload and a shedload of grief. For staff trying to manage the disruption across the network yesterday morning, the flow of information from the company was typically poor. Station staff - responsible for getting information to passengers - found that they could get more up-to-date information from the BBC website or the Evening Standard than from London Underground! Some even found that passengers knew more than they did. This is not just embarrassing - it can become a serious problem if customers think that you are either withholding information from them or don't know what's going on. RMT banged out two press releases within hours of the derailment. ASLEF made a statement too, but with nothing really to say about the issues. TSSA at least managed to link the incident to PPP.

With the length of time taken to detrain a train in a tunnel (or rather the speed at which it is initiated), isn't the decision dictated by the particular set of circumstances surrounding each individual incident? The train operator (alone and in his cab in the tunnel) is crucial in making an initial assessment and decision, another reason why s/he should be paid well, IMO. I imagine risk assessments are made with every decision and they depend on lots of factors - ultimately leading to ensuring the passengers are in the safest place - ranging from an immediate emergency detrainment to other well established procedures and chains of command. The train operator's communication of his initial decision and reasoning to his passengers is probably just as important as the decision itself: news.bbc.co.uk/onthisday/hi/witness/november/23/newsid_3227000/3227456.stm

Jamesb - you're right. The initial actions of the driver and from press reports a "tfl employee" no doubt eased alot of peoples worries and concerns.
However, it still begs the question why did it take 90 mins to commence the detrainment? (figures quoted from one of last nights free papers). 90 mins if it was hot could be fatal. 90 mins if you're on your way to work/ home is stressful for those involved.
Given the circumstances those on the train were no immediate danger, but not forgetting that procedures laid down state that a decision if to evacuate, should be made within 15 mins and then every 15 mins after. It was obvious that it would be impossible to move the train after the first 15 mins - so why weren't those affected evacuated then?

I'm not certain exactly what the 90 minute relates to I've personally not seen it in context. However I think that you would need to ensure that the train trapped between the incident train and the station is evacuated, or at least mostly so, before evacuating the incident train as I guess the pax from the latter would have to walk through the former to get to the station - cramming two train loads of people into one train, or leaving a large group of people in the tunnel is not a good plan. In the judgment of the T/op and TfL employee on the incident train the pax were sacer there than elsewhere.
It might not have been clear after the first 15 minutes that the trapped train wasn't going to be reversed back into the station. I can think of no circumstance where I would have any untrained people in a tunnel with moving trains (without at least one stationary protecting train between tham and running trains) by choice, even if they are in a different current section (and I have no knowledge of power arrangements in the area).
I would be surprised if what happened was not looked at in detail by at least TfL's and the RAIB's investigations. If they find things could ha ve been done better, then reccommendations will be made and, I hope, acted upon so any mistakes are not repeated

Central line incident - update London, 5 July 2007 - A Metronet spokesperson said: "With the exception of essential maintenance, all project work was cancelled last night to facilitate the inspection of network-wide storage locations. A detailed inspection of over 350 storage locations on the network was undertaken last night and the results of this work are currently being collated. “The investigation is expected to determine, amongst other issues, whether the recently upgraded procedures for the use of such storage areas, are adequate. Metronet will act fully upon all the recommendations of the investigation report, to ensure that such an accident is not repeated. “By midday on Friday, 6 July the three lead bogies of the incident train had been re-railed and was being prepared to be moved from the site. An assessment by Metronet engineers has been undertaken of the damage to the area – and a team of up to 100 operatives are this afternoon, commencing the necessary repair works. “Metronet is expected to complete these works tonight, with the objective of enabling London Underground to resume a full service on the Central line on Saturday, 7 July. Separately, in a statement published this morning by London TravelWatch, Brian Cooke, Chairman of London TravelWatch, suggested that the maintenance work carried out by Metronet and Tube Lines was quite different. “Through his own admission, the Chairman of London TravelWatch is “not a safety expert”. To make such serious, ill-informed, and unqualified allegations – is not helpful to anyone. “The facts tell quite a different story. Since Metronet's PPP contracts began in 2003, its occupational Accident Frequency Rate has fallen by 70 per cent. Metronet's record stands up very well against any comparable benchmarking exercise.” And in a letter to Metronet, Brian Cooke asserts that the delays in Metronet's programme and additional costs incurred are a lack of competence by the organisation. A Metronet spokesman concluded: “Mr Cooke would be wise not to pre-judge the outcome of the Extraordinary Review, which was initiated by Metronet only last week.” ENDS

I might be offside here, but as I see it, unfortunate though it was, this episode should be used as an opportunity to learn lessons rather than to sit back and point fingers. But for the fact that I had to be in town early on Thursday, I could so easily have been on the train affected or one close behind.
Whilst the system of "Storage Licences" has it''s merits, it only works if someone with a degree of loyalty to the service provider regularly audits the process - it's reasonably common knowledge that a large proportion of night crews are "agency" staff employed by a company that can be as many as six places removed from the person who signs the PTW/Licence - how can you expect them to worry about the consequences of their actions?
I feel that it's time things were brought back "in house" so that everyone has the same goal, training and level of responsibility to ensure that such trivial but vital things don't happen again.

Perhaps it would be worth having Protection/Possesion Masters employed either directly by the Infraco or LUL, rather than all sorts of Agencies or Sub-Contractors.
At least they would have some (more open) direct sort of accountibilty.
It would be impossible nowadays to have just London Underground, it is far too fragmented, what with all the different work going on, eith PPP, Connect Radio PFI, Tunnel Cooling, Advertising, Step-free access, Power PFI, and the list goes on.
I would hope that LUL and the Infracos learn lessons from Thursday as the same thing has happened a number of times in the past few months. It has only taken a derailment to bring it to the attention of the media, public and staff.

Plus we do have to look at human nature. Regardless of your employer people can (and do) cut corners.
However I do agree that the site person in charge should be an employee of either the infraco, LU or at the very least the primary contractor.

It is interesting to read from the report that 'most of the injuries occurred during the evacuation of the passengers along the tunnel'.

As a lay person who has never walked along the track, I expect that a large proportion of these minor injuries are things like sprained ankles. I am not particularly sure-footed and have hurt my ankles on firm level ground with no trip hazards - ballast cannot be easy to walk on, and four rails make a great tripping hazard. Doubly so if you are wearing footwear that is less than ideal for the task - high heels spring to mind.

It seems that at present everytime a train is stopped betwen stations some passengers instantly assume it is a Terrorist Attack and start to panic. it might be a good idea if the reason for an unusual stop is given to the passengers by the Train Operator as soon as possible. (In the event of a real terrorist attack it might be desirable to tone down the details !) Should there be any sign of panic other passengers, who have kept their heads, could take some charge by calling out in a loud voice ( even if it make you feel embarassed ) their possible reasons for the delay and attempt to calm down the other people. I have not ben involved in a similar delay myself as a passenger but think I would be capable of calling out anouncements- having been a Suburban Guard here in Melbourne.
