Northern line trip failures = lots of SPADs
Something no one in the media or on here seems to have mentioned is
that the only reason the drivers are noticing so many tripcock failures is that so many of these overpaid agitators are going through red lights! Perhaps while they're fixing the trains they should consider getting the drivers retrained. How exactly can you miss a red light in a slow tube train usually (on the northern line) in a dark tunnel? They don't have to worry about other traffic , roadside distractions, steering etc like a bus driver but if a bus driver went through a red light I don't think anyone would have much time for him blaming the bus for not putting its brakes on!

Perhaps the reason it hasn't been noticed is that your assumption is false. The fault is said to occur when trains are driven through a red light very slowly, as happens for example in the case of a track circuit or signal failure where a driver is given permission to do so. The procedure is to go forwards slowly, get tripped, reset the tripcock and proceed at slow speed to the next signal or for 3 minutes, or something (I forget the details). It's been found that in these circumstances, the tripcock can reset itself without stopping the train.

Boltar...you been on holiday or, perish the thought, everything been going
as you liked for a while. I've missed your abrasive people hating comments recently, welcome back. The reason so many have been highlighted recently is......... They have been testing them. Hence every train tested means a number of failures hence the situation we are in. Its got nothing to do with them all SPADing. Why hasn't it been picked up before? Probably because the trip cock test that has to be done by every train leaving a depot or terminus, so, many times a day. It is a test to ensure the arm is not missing or out of alignment with the train stop at the signal. It doesn't operate the trip cock. If it did the arm would miss a train stop thereby rendering the train capable of going past a red. In these cases the arm is correctly aligned, it just doesnt open the valve. So the normal trip cock test works fine. Also, judging a red in the dark with no referance points isn't that easy. Thats where line knowledge comes in. If it wasn't for the profesionalism of the drivers, or operators, trains would SPAD all the time. And we would have found the tripcock problem years ago...... The qustion Boltar you should be asking is how much will the contactor pay for the disruption. Will it make a huge dent in profits.....if they get found to be contributing to the delay at all. I have no idea how the system works....perhaps other do and could enlighten us. Mal "Richard J." wrote in message .uk...

It's contractors plural isn't it? Don't Alstom provide and maintain these trains for LU on the never-never? It's my understanding that the original Alstom contract was passed to Tube Lines, who now have Alstom as their subcontractor. -- Richard J. (to e-mail me, swap uk and yon in address) |

One would hope that such a safety critical feature is tested on a regular basis, rather than it taking a SPAD for anyone to notice there is something wrong. |

On the one hand you have these highly trained, safety critical £32000pa or is it £35000pa drivers, who should be capable of stopping a train at a signal. Or are they irresponsible idiots who require a safety device to stop them at a signal so that they can concentrate on their ipod. Surely the purpose of the tripcock wasn't as a safety device just to save the embarrassment of negligent drivers. Kevin |
