Is Connect helping or hindering the recovery from the emergency works that were undertaken at Monument? I can't help but notice that the Circle is suspended and the H&C severely delayed as well - what happened at Monument?

A signal failure according to the messages I saw around 10am.
I suspect though that it is more likely to be track circuits or something of that nature as rather than a signal bulb unless it went bang in a spectacular fashion.
The clockwise (iirc) Circle was suspended first, although the District hasn't been that I've seen. It is unusual that the H&C is suspended from Liverpool Street rather than just Whitechapel which is where they normally truncate it when things go belly up.

The H&C is now shut east of Whitechapel and running every 10 mins. It was originally reversing via Aldgate because the District were using Whitechapel and also the blocking back in the area.

yesterday they had a report of a signal with no green aspect out when the t/o checked he found this was actually caused by the signal relay not energising properly then on closer look found that the track circuit after the station starter (w/b) was actually failing they went and changed a blockjoint last night but when it came to testing the circuit it was behaving in a strange way for those that know the relay was driving backwards i was called from earls court at 5am this morning to see if i could figure it out we stripped down the joint again tested it again and the joint was ok but still the signal was failing the duty signal manager was also there aswell as my SOM (signal operational manager) and none of us could work it out so looks like back there again tonight but through thinking and discussion today we believe it to be a cable problem but this is just specualtion until we are able to test it properly for info the traction current came back on at 06:03

Thanks, aetearlscourt - it's that kind of reporting that makes this forum enjoyable for all  I am curious to know what you mean when you say that a relay was "driving backwards" - does this mean that it was changing the pattern of open/closed/front/back contacts in unpredictable ways? |

each track is what they caused opposed so one track circuit cannot feed another if a blockjoint failed but if the blockjoint did fail it could drive the other relay backwards (the is other ways you can tell if a b/j has failed) only time you dont get a track opposed is usually by traction current gap sections or in some platform areas

As stated this all kicked off yesterday and it was not resolved overnight. From a 'trainside' point of view, it was presenting itself as an intermittent failure - some trains were getting through the area without problems whilst others were having to go through 'under rule'. In a further attempt to sort it out the ERU this afternoon replaced a blockjoint (presumably tyhe same one?) and this resulted in a suspension between Mansion House and Whitechapel both roads. Sadly it didn't resolve the issue. At one time services from the west were going as far as Whitechapel and there was a shuttle service between Whitechapel and Upminster using 4xx numbers. Passing Ealing Common Depot several times during my shift revealed a much higher than normal number of trains 'resting'! Also of interest was the High Street <-> Wimbo service of D Stocks bearing 07x numbers! Sadly I didn't have my camera  As to the original question so far as I could observe the improved performance of Connect was a great help - the Controllers seemed pretty much in touch, albeit they were rather in the same position as Canute holding back the incoming tide! |

On Thursday we had some problems in this area, but on my one trip through I managed to get green signals. Saw one 4xx train running Upminster - East Ham.

correct dave it was the same blockjoint and as of 19:00 roughly it never failed again i was there all night which seemed to be every man and his wife from metronet there and yet we found nothing to cause the failure in total just for interest metronet was fined by lul for £425,000 for the delays and cancelations

Sounds like one of those classic things - and I bet as soon as you turn your back it drops again lol!! Now - perhaps I'm being simple here - but why does it need all these people to turn up - other than it makes it look like they're 'doing something' and gives them an opportunity to wear their orange coats maybe  It's the actual techs (such as Pat) who actually know what they're doing, so let them get on with it perhaps? £425,000 sounds like a lot - but I wonder if it covers even the Customer Charter refunds and overtime bills! |

It sounds like another OP2. They'll probably want an invasive and unnecessary signalling modification next, just to make it look like they're doing something. Oh - and I don't need to go to Monument to wear my orange coat... |

Good thing the shift wasn't aborted then. All those senior staff wages paid out for no work done. |
