Anyway, getting back on topic. I notice there's only one more closure of the central section currently planned between now and June (18th/19th January, Stockwell to Angel via Bank and Stockwell to Euston via Charing Cross) and no closures (currently) at all after Sunday 13th April. Are they running even earlier than the original June completion then?

I have heard that Jan 18/19 closure is for the final tests, preparations and dry runs for the introduction of NMA4 into live service. if that is the case and if it all goes well then presumably we can expect NMA4 to go live towards the end of Jan 19th or on Jan 20th.

As of 1800 today TBTC is in customer service in the NMA4 area (Euston/Angel-Oval) for the rest of today and all day tomorrow (Sunday). Decision on Monday and beyond will be made tomorrow but looking promising

Wasn't it meant to be testing out of service all weekend?

Wasn't it meant to be testing out of service all weekend? Plan was always to test until confidence was high enough and then enter service but with a closure advertised in case there were any issues. |

Will the W&C line still run tomorrow or not?

Out of interest, why will trains run through in passenger service, as presumably there are insufficient staff to open any intermediate stations (except interchange stations of course) as closures was supposed to be all weekend, or was that planned for and there are actually staff available?

Staff should have been booked on as normal and as another poster has said it is all working ok. In addition NMA4 will remain in revenue service from start of traffic tomorrow so NMA4 is now commissioned. |

The sad individual I am, I just went for a ride on the northern line from London Bridge to Euston and from Euston to Kennington. The dwell time at stations seemed quite short (thats a good thing) and the approach into Tottenham Court Road seemed quite brisk, given the platform was crowded near the tunnel opening. I can't wait till the whole thing is ATO - at this point, will they turn the speed up?!  |

I went on it today via Bank. As at other stations, exit seemed to be noticeably faster with a brief brake before accelerating again. Some parts, e.g Angel to Old Street seemed very nippy indeed. Not a lot else to say about it really.

They won't turn the speed up as such, but the timetable will be re-written to make use of the shorter headways, so more trains per hour, but not much faster than now. I went on it today via Bank.

Not a lot else to say about it really. Was it as uncomfortably jerky as always, or have you grown immune to the effects of the ATO? |

Tried the Norhtern line between Waterloo and Euston CHX branch this morning. Very impressive and smooth.

Great news. Really looking forward to taking a ride once the whole line is operating TBTC and the power's jacked up :-)

They switch back to lower performance at the boundary. However, unless you get on a train running late with nothing in front of it you won't really notice that much difference until the new timetables later in the year. Also some track work needed to remove more speed restrictions. |

Sudden bursts of power on platform approach at Bank NB, inexplicable heavy braking and heavy acceleration in the tunnels... it's really not very smooth at all, IMHO. Different when seated, however. |

Yes still hurrendously jerky on the Bank branch, less noticeable on the CX side partly because the speed profile is more constant. The amount of speed changes on the Bank branch is unbelievable. I'm not sure how many of these are temporary, however still loads of TSRs in the NMA3 area. There is a partial answer to the uncomfortable ride - it's called PM - however driving in PM under this system is so unpleasant for the Train Operator that you have to be mad to do it! It is perfectly possible to keep to time in PM. |

For those of a non technical nature, what section is NMA3 and what does PM stand for in this case please?  |

Northern (Line) Migration Area 3 and Protected Manual. As a point of detail, NMA actually stands for NEW Migration Area. Under the original Tube Lines plans, the first section to go over to Seltrac signalling would have been Morden to Stockwell. When LUL took over the project management the plan was revised to start with the (less risky) High Barnet to West Finchley section, and the rest of the line was re-planned accordingly. Seen plenty of official documenation incorrectl referring to Northern Migration Area though! |

What are the boundaries of each new migration area out of interest?
And which NMAs if any are still to be commissioned?

I had a nagging doubt that Northern wasn't right, but in checking found some official notices using that term so thought I was just suffering from self-induced paranoia! Thanks for the correction. |

Using the Northern Line from Stockwell to London Bridge for 20 years, I've only known there to be 4, 2 for the CX branch and 2 for the Bank. You could at one time at the southern end of the CX northbound see the mimic diagram of the four lines, the loop and the dead end siding. Is that what you are referring to? |

You are talking about the "automatic mind" you could see the diagram and watch the programme machines work spent a few hours doing that in the early 60s. |
