Installation has already started but you won't see much as there is not a lot of lineside equipment Have they started installing the line side equipment yet? Im guessing there will be less than what we've got on the northern line as i gather the atc system will use radio rather than induction loop? |

What exactly is meant by 'Hammersmith IMR'? I didn't think the new system had anything we would call an IMR and I thought the old signalling was worked direct from the miniature lever frame? |

The new system will have to work with the old so wiring within this room may be necessary.
Lots of new equipment rooms being built at the moment.

The track circuits and signals may disappear with the new system but of course point detection will never disappear and needs to be inter grated into the new CBTC system |

The track circuits and signals may disappear with the new system but of course point detection will never disappear and needs to be inter grated into the new CBTC system One that is more for the ATC thread but the points will be detected and controlled by the SCS (Station Controller Subsystem) in the new SERs (Signalling Equipment Rooms). The IMR connections are, I believe, to do with the ability to "over and back" from legacy to ATC during testing. On Jubilee and Northern there were cut-over cubicles to avoid the need to do lots of wires off / wires on during the over and back process. On 4LM plate racks are being used for the same function. That's pushing the limit of my understanding of the topic. |

Thank you, makes a lot of sense  I'm still surprised though, I didn't realise Hammersmith Met had an IMR, or is its N frame considered an interlocking machine even though it's worked manually and is the signal box considered an IMR? |

They should be classed as Relay Rooms really not IMR's

Looks like all but one have been delivered now, I can't find what the 'A' means in the delivery list of the outstanding unit. Did they fit the new signalling equipment to any new units before they were first delivered, or will all units be heading back at some point in the next two years?
Saw 559 in service yesterday, and got 557 home from Tower Hill. Are they using different lights in the later units? It felt very bright heading home at night but I am not sure whether it was just the near perfect floor reflecting more light back up.

Outstanding others (21381 21383 21385) may also be fitted. |

A nice touch on T125 as it waited west of Earls Court for a platform circa 740am this morning: the driver announcing 'there are only ten D stock trains left in London and they should all be gone early in 2017'.T125 is one of the core always D stock runs, and for regulars like myself on this service it was a nice touch given this leg is always virtually a crush load and badly needs to be an S stock. One hopes the eventual line upgrade increases direct trains to Central London at this time of day also. This train is eight minutes after the previous 'city' train and eight minutes before the next one, not optimal to being a D stock perennially.

Think the announcement may have started: "you may be interested, disappointed or pleased to learn this is one of only ten of these D Stock District Line trains remaining in London . . . . . " yes ? T125 is expected to lose its regular D Stock when that service is extended to Tower Hill on 10 October, as Mansion House ceases to be a reversing point after Friday 8 October. (another similar announcement maybe made as the same driver should be on it) |

A nice touch indeed, it generated some smiles amongst the passengers and was well received around me. |

(another similar announcement maybe made as the same driver should be on it) Nice touch ! Latest on the delivery of S stock as of last Saturday There are 126 S7 in London. 121 are delivered to SSR depots and 5 are at Ruislip still to be delivered and put to use over the next few weeks. 126 is the maximum number in London whilst the ATC fitment progress but the last 7 S7s will be brought down over the next couple of months and swapped out with older trains that will then go off to Derby. There are 11 D Stock still to be removed. A plan to hold onto up to 10 of these into the new year, to support release of S7s for ATC fitment, is being considered. |

It might have already been covered, but what sort of order is is the ATC fitment being done in? Also, are all of the S8 mods that they were undergoing now complete, but they'll have to be returned for ATC fitment as well?

Also, are all of the S8 mods that they were undergoing now complete, but they'll have to be returned for ATC fitment as well? I think it has been on the signalling thread. Up to 6 S7s and 4 S8s will be away for fitment at any one time. There is no particular order set number wise except for some internal requirements such as no more than x number of de-icing trains away at any one time (I can't remember what x is). The only other requirement is that at least 53 S7s must be done by SMA0.5 (although in reality a lot more will need to be done otherwise later milestones won't be met), all the S8s done by SMA2 and the remainder of the fleet by SMA3. |

Anyone know why 21413/14 still has the old "Please mind the gap between the train and he platform" guy?

Am I right in thinking that there will be *two* permanent S7+1s, now that two of the donor sets now have new cars to replace the missing ones?

There will be two surplus M2D cars

I thought there was to be one spare car. 23582 has gone back into Train 99. 25384 and 25386 are still in Trains 70 and 72. I believe Train 72 is the extra S8 (actually S7+1!) for the Croxley extension. If train 70 reverts to an S7 in time, 25384 will become spare (unless it replaces 23384, which becomes spare) ??

Yes indeed, my mistake. I forgot that 21381/82 is getting its original 25xxx car, and not a new build 23xxx replacement. |

Class 20s with match wagons in Neasden Depot during the day. Presumably another train off for ATC fitment tonight? Whether an ATC fitted train was returned to London last night, I don't know?

A fault with one of the class 20 loco was discovered hence why the train never left Neasden
