It sounds as if too many met trains were allowed onto the circle.

I cannot see unreliable power supplies ever being used for safety critical equipment, to be fair a signal with a failed red aspect does fail in a safe way as the train stop would trip any train passing it.
There are solar panels on the Chesham branch to power the lights on the lineside telephones.

It was then doubled isn size for the introduction of the 95 stock and point work was installed on the back of the roads, "at great expense" to allow the rear on a road train to leave the dopot without the front one moving, this was never commissioned and I don't know if it is still there.
It was a contentious point as to whether Higate is a Depot or Sidings as this affects whether trains should be brought out with certain "minor" defects

It is very rarely used, opening one set of doors on a train just encourages a rush to those doors and can cause more delay than opening them all.

There were two half way between Chalfont and Chesham, these have disappeared within the last couple of years.

Thanks whistlekiller. The cost of a 20 metre platform extension would be very hard to justify given the fact that many if not most Chiltern trains are 2 or 3 cars. As philthetube points out cars/doors can be locked out. To extend the northbound you would have to either build onto the bridge or demolish the signal cabin, possibly an option in the future but not at the moment. Southbound may be easier.

The first issue can also be mitiagted against, I imagine that this system would not allow the doors to open until the gap fillers were in position, but would you want the delays.

You occasionally see a 6 car calling at Ricky with the rear car locked out.

I believe that platform length at Ricky is what determines the maximum length of Chilterns services. 5 car max

The platform could be extended south to the bridge, that would work nicely for Chiltern. for what purpose? Shuttle service to Watford Junction, to connect with Aylesbury service.

Shuttle service to Watford Junction? (I wish) there is not enough space to accommodate a train and no way of extending it without demolishing the station building. The platform could be extended south to the bridge, that would work nicely for Chiltern.

Ah, that explains it. My memory of guards was mainly from my childhood, when they were in carriages, and had a small panel containing a fascinating purple light (marked IIRC 'Pilot'). [TIC]They had a bar so that when things got really crowded, they could make things even worse by reducing the size of one of the carriage they were in. [/TIC] Could you imagine if they didn't use the bar and had to squeeze there way back and forth across the train in the short interval between gaps. Oh the dwell times Especially as the buttons were live and it was possible to open the train doors at any speed.

If the formation is there, then it's not truly permanent. It sounds like there are no plans to use it in the foreseeable future, but how far ahead is that - almost certainly less than 75 years. I accept your point but what would be the use of a very short siding? Shuttle service to Watford Junction? (I wish)

The train on platform 3 had movement problems so the aldgate service was diverted via platform 2, it is not a common move but not unheard of
Platform 2 does not have CCTV for the driver to monitor the platform so assisted dispatch from station staff is required.

does anyone know if there has been a serious drag issue with a sensitive edge fitted train?
|

Post by philthetube on Jul 1, 2016 18:48:45 GMT
A drag incident should never occur with S stock because of the sensitive edge equipment fitted. (also on Victoria line). This immediatley cuts out the motors if the train starts to move with anything trapped in the doors, and seems to be very effective, it had teething problems but now seems to work fine with very few false warnings. I cannot understand why it is not installed on new mainline stock, and I would have thought it would have been an easy retro fit on any train with "plug"doors.
As you say, the GPS incident was in the 70s and I don't think that could happen now with modern stocks.
I will let someone else describe how it works as I would struggle to do that legibly, but if no one comes back I will have a go.

At about 23:50 the harrow terminator pulled into Plat 3 and the Ricky local on 4 and everyone looked around in confusion. Total chaos! The guys thought that perhaps both trains were going to Ricky space permitting. Goodness knows what it was like at the start of traffic this morning! Yeah, I didn't think it was possible to reverse from HOTH platform 3? It would probably be a rusty rail move reversing via Rayners Lane Westbound Platform.

you can occasionally see clouds of dust anywhere on the system , especially after engineering work, I am surprised that dust remains in the same area though.
When working as a guard on the northern line many years ago, in the days of white shirts, there was no question of going out after work without having a shower first, the water used to be black around your feet and when you blew your nose there was no trace of green for all the black. It is a lot less dusty now because of different braking systems.

I think you were being very optimistic trying to catch the 0016 train. Bearing in mind that there were approx 70,000 people at the concert. When I have traveled from Wembley after an event I have been both surprised and impressed by the way the crowds have been dispersed.
As you say walking from Marylebone to Baker Street is about the most you can manage and that is a similar distance to the walk from the stadium to Wembley Park I cannot imagine you walking that is less then 20 mins without other people getting in the way, From experience you cannot get out of the Stadium in less the 15 mins. That would take you to 2305 before you joint the others wanting a train.
So assuming 2305 at Wembley, five mins to wait for train, not allowing any time for crowds, fifteen mins journey to Baker St. ten mins change time, 7 mins journey to Kings Cross, (which was busy that night), puts you on the platform at Kings Cross 23.42. 34 Minutes to get from kings cross platforms to ST@. for a person who is not a fast walker does not leave a big cushion on a normal day and I have not made any allowances for not being space available on the first train to arrive at Wembley.
Station staff at Wembley cannot do much to improve throughput of passengers, you can be sure that if you were held in the ticket hall that would be because there was no room on the platforms, it must have been station staff who were holding you. There were certainly plenty of staff on the platforms, they control flow of trains through the station ensuring they leave loaded and do not delay services behind. Drivers are told by station staff when to depart.
I suspect that your minimum time for that journey would be one hour so to attempt it after a concert with an extra 30 mins is optimistic.
Journey planner shows 36 mins from the Bobby Moore statue to Kings cross underground. I think that backs up what I say.
I cannot comment on your inward journey though.

Jubilee line trains are 8 car No Phil, they are 7 car extended from the original 6. Oops got that one wrong, was thinking length, they are near enough the same length as the 8 car S stock. although not quite as the S stock will not go into Wembely Sidings, which would be useful for football.

Great! Should help sort out some of the leisurely running at times, and also some of the annoyingly slow approaches to stations. Stand at Finchley Road sometime and compare arrival speeds between Met and Jubilee trains southbound, Met trains enter the platform a lot quicker.

Other than replacing signalling systems, introducing new faster higher capacity trains and expanding/rebuilding stations is there anything else they can reasonably do? Have they ever lengthened platforms - would be useful on all lines particularly the Northern, Piccadilly and Waterloo and City Lines. Naturally this would cost large sums of money and take time but it would be worth it if it was practical and when new trains are eventually introduced they could be 8+ cars long. Recently they have had those smallish tunnel excavators used to create cross passages in creating new station cross passages that could be used. Also on the Jubilee line Extension the platform edge doors end about 3/4 or a cars length away from the end of the platform. Its always baffled me that with a bit of reorganisation of the PEDS although not feasible now but in the future they could increase train length to 8 maybe 9 at a push cars. On the rest of the line there are only 5 deep tube stations and although these would need more major work to lengthen with the street level/cutting platforms shouldn't be too difficult to increase capacity that way. Jubilee line trains are 8 car

the doors make enough noise without the chimes, and the sound of the doors opening is more location specific than a chime which comes from one corner, and could be either to the left or right of the doors .
I don't think the chimes sound in passenger open mode unless someone opens the doors but I will check.
