This weekend, the Met is suspended between Moorgate and Aldgate.
Was just wondering why this is happening? Is it because the H&C is suspended east of Liverpool Street and the Cirlce is running?
Thanks

What do you mean? The Tube website says it is suspended Liverpool Street - Barking This is one of those technical-type things Tfl do from time to time, and it's all a bit pedantic of them to be honest. Much better to properly spell out what's happening, rather than use a cut-and-paste standard format for all engineering work. In short, the Hammersmith & City Line runs from Hammersmith to Barking. It doesn't run to Aldgate. Therefore, with H&C trains running to Aldgate to reverse, then technically the H&C is not running along its normal course between Liverpool Street and Barking. |

Oh okay I get it now.
But isn't there a crossover at Liverpool Street?

There is indeed a crossover at the Paddington end...

Oh okay. I imagine it would be quicker and easier to detrain at Liverpool Street and reverse at Aldgate rather than reverse at Liverpool Street with the Circle Line running as well  |

It should be advertised that the H&C is running to Aldgate and be done with! The other option is to run to Aldgate and not tell any one!

The H&C trains are scheduled to be in passenger service between Liverpool Street and Aldgate. Trains generally have a 15-minute layover at Aldgate and both platforms 2 and 3 are required, hence the Mets being turned short at Moorgate on this occasion.

I just realised.
Why isn't the H&C being turned at Moorgate and the Met operating to Aldgate?

Yes, techically the other end is also the Paddington end, it just takes longer to get there!!!  The Met will reverse at Moorgate I would imagine to improve reliability. The shorter the train service, the more reliable it tends to be. |

I just realised. Why isn't the H&C being turned at Moorgate and the Met operating to Aldgate? Not sure to be honest. It's quicker to run C-stocks in and out of Moorgate than to turn A-stocks there. It doesn't work this way, but it's almost as if the H&C said "We can't go to Barking, so can we run as far as possible along our booked route and turn at Aldgate?" with the Met replying "Yeh ok, we'll turn ours at Moorgate." My money is on a) The H&C being planned first, and the Met having to be accomodated for their changes or b) It's some sort of pre-extended Circle timetabling experiment type thing that Mr mrfs42 has hinted at in other threads related to the planning of things in the future. As a side note to this weekend, and of interest to our Jubilee Line viewers, the Met will be stopping additionally at Willesden Green Station in both directions, as a substitute for the Jubilee Line. |

No, I'm afraid not. This weekend anyway.
The arrangements were signed off at quite late notice, and the additional time taken to stop at Willesden hasn't even been timetabled in. So the odd minute or two of late-running will occur, and there will be those trains which won't stop, simply to ease congestion.

So will the Fast Amersham/Baker Street trains not stop at Willesden Grn?

If I were a betting man, that's where I'd put my money; thinking off the top of my head along the lines that Aldgate with stand time to the H&C during closure is or will be similar to a West Ham reverse. Do you get my drift? I might be very wrong in this, but looking at a Met. example with clockface departures at xx ax 0½ from Baker Street and arriving in Aldgate pfm 2 or 3 at [xx ax 0½] plus 15½ minutes, there is then terminal stand time before departure of 13½ minutes - giving a clockface return time from the middle platforms at Aldgate of xxx 9½ - thirty-nine minutes after leaving Baker Street. How does this translate into a West Ham reversal time, I wonder - well Plaistow reversers take 32½ min to do BkS - Pstow. That would translate into 2 minutes less for arriving at West Ham. So, based on the assumption that the Aldgate reverses are a dry-run for West Ham reverses and based on the data I've got sat next to my 'pooter ( pile of TTNs awaiting accessioning) I'd go for a first-order guess of 30½ min transit time and leaving 8½ min reverse time - plausible yes/no? ;D ;D My thoughts may have been coloured by reading 125/09 - Track Renewal at Bayswater nothing further round than Edgware Road - making it into a Barking/Whitechapel to Edgware Road service |

How come the Uxbridge branch is closed this weekend?

Commissioning of new track circuits is taking place in connection with immunisation work on the signalling system for S stock.

I'm sure the Uxbridge branch will see more and more closures as the works that have been undertaken so far on the Amersham and Watford branches are started in earnest there...

I would like to turn that around - to a more positive stance. The Uxbridge Branch will see less and less closures as the works to enable smart new trains to run are completed. |
