Yes thats true! If the kit stays there any longer they will have to start giving the bin liners covering them asset numbers!

How did the testing go - is the NMA6 commissioning still on schedule? Will there be a period of "asset removal" once TBTC is running throughout the line, as per the VLU? NMA 6 been delayed by two weeks now expected weekend of 31/5 - 1/6 |

There wasn't much on the jubilee, lots of the old assets are still there. Asset recovery is due to finish around October last time I checked. Will only involve "driver facing" assets such as signals and signage. |

On the Northern I don't believe any significant asset removal has yet occurred, last I heard is there is no programme in place, though this may since have changed. Having said that, the former trap points at Finchley Central I believe have been removed (never thought to actually check!), and I've noticed a shunt signal at East Finchley seems to have disappeared during the recent track renewal works. On a different note, noticed there is an internal communication referring to removal of 77 speed restrictions on the Northern Line. Anyone know any more? Not yet been out on the line to see if there is any difference in performance. |

The asset removal works on the Northern line are being planned but as you say there isn't a programme yet; least not one that I have seen. There's a big package of speed restriction removal due just before WTT54 with a new VCC build so you should see more of an improvement during mid to late June. Has been a long time coming I know. |

Really looking forward to the speed restrictions coming off, let's hope this really makes a difference and provides some sense of 'upgrade'. At present, from an operator's and user's point of view I find it hard to find any positives with Seltrac, especially compared to other ATC systems. |

Full, all weekend closure of the Edgware branch showing for this weekend for testing of NMA6. Is the plan the same as other NMAs, start passenger services some point over the weekend assuming all goes to plan, or will this definitely take the whole weekend?

With a new timetable from 22 June, with two extra trains in service peaks (93 instead of 91) and five extra trains off-peak, if you can call it 'off peak' these days (77 instead of 72).

From the LU Intranet -
Whole line has transferred to new signalling system
The Northern line signalling upgrade was completed this weekend, with the final section of the line having transferred to the new transmission based train control (TBTC) system.
Trains are now running in TBTC mode throughout the Northern line, from Edgware, High Barnet and Mill Hill East in the north, on both the Bank and Charing Cross branches, to Morden at the south end.
Following a successful first afternoon in revenue service in the Northern Migration Area Six (NMA6; Chalk Farm to Edgware), the decision to continue operating the TBTC system in this area was taken on Sunday afternoon.
Increased frequency and capacity
With the system operating throughout the line, new timetables will be implemented between June and December this year to make use of the improved runtime offered by the new system.
Track replacement and other infrastructure works will take place between now and this autumn to ensure these assets are in optimal condition to accommodate the increased frequency of trains.
When the upgrade is complete, the line capacity will increase by 20 per cent. This means we will be able to carry the equivalent of an extra 11,000 passengers an hour. At the same time, journey times will be reduced by 18 per cent.

"Track replacement and other infrastructure works will take place between now and this autumn to ensure these assets are in optimal condition to accommodate the increased frequency of trains". That explains the Camden Town to Kennington via Bank closure this weekend, thanks.

The new WTT54 timetable is now in the Journey Planner from 22nd June onwards.
Off peak frequency increases from 15tph to 18tph on each branch.
Peak frequency will be about 22tph.
As for journey times, off-peak High Barnet - Morden via Bank goes down from 1:15 to 1:09 and High Barnet - Kennington via CX goes down from 44 min to 41/42 min. Edgware branch times seem unchanged, presumably because it has only just gone live.

As I understand recoveries are not in Thales' scope and may well be done internally. |

I'd hope so as well, but the next closure of the northern line is August - will there be enough line speed improvements between then and early December (possible new timetable) to give the better service

the new timetable is fairly unimpressive to me. Barnet - Morden via Bank is now timetabled as 1 hour 9 minutes, a 6 minute reduction from the mon - fri working of WTT 53 which was driven manually until the transition. It's worth noting that the same run time of 1 hour 9 minutes was the allotted time on sat / sun working under WTT53.

Is the entire Northern Line TBTC operated now?
if so, when trains go through embankment, do the pass through at 20KPH like on the Jubilee?

Trains go through any closed station at 30kph / 18mph Is that all roads in High Barnet sidings, only I seem to remember when NMA1 first went live, I think 34, 36 and 25 roads (and 32 road?) didn't have TBTC. Is that still the case, or do they all now have TBTC? Just to clarify  |

Is this weekend's closure of the Northern TBTC related?

Just wondered, is there a date for completion of the upgrade yet? i.e the start of the new timetable with enhanced frequency and reduced journey times.

Is the timetable change going ahead this month? Yes as from 14 December WTT55 comes into operation. M-F: 3 additional trains are scheduled from Morden depot in the peaks, with 96 trains now out in each peak. 'Stepping-back' of drivers introduced at Morden in both peaks. During the morning peak 26tph NB Bank branch, 22tph NB Charing Cross branch. In the morning peak NB 30tph now run NB from Morden for 90mins, this is reversed to SB in the evening peak.NB peak services have been reversed to operate to Edgware from Bank branch, High Barnet/Mill Hill from CX branch. At off-peak times a 20tph service runs in the Central area, with 80 trains in service. SAT: Services increased to 20tph throughout the line with 80 trains now in service. SUN: Before 1000 services increased to 18.25tph in Central area. Charing Cross branch trains continue to terminate at Kennington. After 1000 services increased to 20tph throughout the line with 80 trains now in service. |
