The bit I find strange is how if it became detached from a towing train to managed to head south on the Southbound during normal running hours. Does the tube have tripcocks installed as part of the signal interlocking as standard? Peter I identify as half man half biscuit - crumbs! Log in to reply |

The story going round on the Freightmaster Forum is that it was a rail grinder with its brakes isolated (for whatever reason), which then proceeded to become detached from its train (failed couplings were mentioned).

On the Underground when a train is being towed via the emergency coupling the air and tripcocks are isolated in accordance with the rule book.

I'm still perplexed as to how it ran South on the Southbound by a train towing it unless the train was moving North on the Southbound but it appears there were service trains around which would make that difficult. If it was towing North on the Northbound there is no crossover to the Southbound till around Mornington C and it must have been moving South on the Southbound otherwise running trains 'fast' in front of it does not make sense.

It was moving North on the Southbound "Bang road" in underground terms. The brakes on the grinder where isolated, and so where the trip cocks. The trip cocks have to be isolated on the failed train, otherwise you would get "middle tripped".

Yes that was the only thing that made sense to me save that the report indicated a near miss at Archway of a service train which implied there was a Southbound service train running as normal while all this was going on which made me question the accuracy of the report.

During the period between normal start of service and the time of incident, because of the initially broken down engineering train blocking the line, the service was operating as far north as Archway, and reversing via the siding there. When the incident occurred, the 1 service train affected had just arrived at Archway southbound platform. Despite what the media will have you believe, there was only 1 service train that needed to be "got out of the way" so to speak. Whatever the outcome of the inquiry, the quick thinking of the Service Control staff should be recognised - both in getting the service train out of the way and in their attempts to stop the runaway train (with the use of points set against the train being one method employed.)

metcontrol said:(with the use of points set against the train being one method employed.) Meaning deliberately allowing points to be run through? Good thinking, but it can't have helped the recovery from the incident - running through locked trailing points can cause a lot of damage! Good work on the controllers/signalmens'/regulator's part though... it had the potential to be very nasty, by the sound of it. Log in to reply |

Of course it is, but pointwork damage can be fixed a lot easier than people can. Anyway, what do you call a noteworthy speed, the Northern Line trains have a pretty low max speed of 45MPH (limited from 65MPH). Log in to reply |

Just thought I'd mention 'The Tubeprune' - apart from the interesting pages, including various London Underground signalling pages, there are some interesting Route and Track Diagrams, including Northern Line diagrams, like the one for Archway which is related to this incident.

Without stirring the wrong sort of debate, or revealing anything "sensitive" to the inquiry itself... Regardless of actual speed limits, the runaway was just that, and could (theoretically) have reach higher than normal speeds. (It didn't though.) The setting of the points was done to try and achieve any slowing of the train that they could. Some reduction was, I understand, achieved and that probably contributed to the location it eventually stopped at. Had some speed not been taken out of it, it may have made it all the way to the top of the hill that stopped it. Not sure off the top of my head how far the up-hill stretches, or what comes after it.

RAIB notification of Investigation into the runaway of an engineering train from Highgate to Warren Street on the Northern Line on 13 August 2010. {Strictly speaking this thread should be in the 'Open mic' section} I can only help one person a day.

A fair few of those appearing - all apparently from "senior staff members / highly placed sources." "And a leaked report reveals the driver of the engineering train jumped clear at Highgate Tube" Not that leaked considering the fact is mentioned in the brief on the RAIB site. I've watched that replay first-hand at normal speed, not the 20x speed it was being watched at - which tends to increase the corruption in the data it shows. The corruption in this case shows the engineering train a lot closer than I saw it. Not denying they were close, but clearly this "Highly Placed Source" has intended to create a little more drama than if it had been watched slower. Log in to reply |
