There are not enough depot spaces converted to run with all S7 trains. The situation as from end-of June: Ealing Common requires 22 trains to enter service (M-F am), 2 of these must S7 for Circle/H&C, 2 of these must S7 for Edgware Rd. Ealing Common currently has berths for 32 S7 Stock or 29 D Stock. (15-17 roads out of commission, 3-11 Ealing temporarily enabled for S7) Upminster requires 34 trains to enter service (M-F am), 3 of these must S7 for Circle/H&C. Upminster pfm.5 requires 1 train to enter service. Upminster currently has berths for 37 S7 Stock or 44 D Stock. (1 road remains out of use for either) Lillie Bridge requires 12 trains to enter service (M-F am), 2 of these must S7 for Edgware Rd. Lille Bridge currently has berths for 12 S7 Stock or 9 D Stock. Parsons Green requires 7 trains to enter service (M-F am), 3 of these must S7 for Edgware Rd. all 7 roads at PG are compatible with both Stock. |

The D78s are now effectively a 'free train', whereas use of the S7s will take them a few miles closer to their next major exam. When the D stock run out of miles (or they sustain any major failures) they will simply get withdrawn and sent for scrap. Why have something sitting around doing nothing that you've already paid for? I'm sure people appreciated being on a sweltering hot D stock today when there was an air conditioned train fully fit for service cooling itself in the depot! As far as I'm concerned, this is an "own goal" Carriages used to have windows that OPENED. There was never such a problem as broken air con, 'cos it wasn't needed!! |

The D stock do have opening windows, but it doesn't stop them being sweltering! Not sure if any S stock have suffered from broken air con, or whether this would be a reason to keep one out of service. |

Just because they've been delivered doesn't mean they're serviceable. Correct, but it's been stated on here before that there is a policy in operation to run as many D stock as possible. So this implies that if there Is a D and an S both available for service, the D will be used. With 116 S7's now commissioned and available for service, and a District line peak service requirement of 76 train and H&C of 33 trains, this would need 109 S7's. This would mean that there are 7 spare S7's. My point is more to do with the fact that if they wanted to, they could run a full S7 service now. It is true that 109 is the service requirement. However, of the 116 S Stock some will be on a planned maintenance day and there will be some casualties to be dealt with. Suffice to say there haven't regularly been 109 available so far hence holding on to a slightly higher contingent of D Stock for a while. And, as was said earlier, the D stocks are pretty much "free" so they will get run for as long as possible. |

So I take it the D's will run until their mileage clocks up enough for their next inspection, at which point they will be withdrawn? I'm assuming that anything beyond basuc checks will no longer be done? |

Remember the S stocks have to be fitted with the new signalling equipment I understand some D stocks are being kept back until they have enough S7's retro fitted

It has been suggested several times but the plan is still to have all the D stocks gone by the end of the year. Until they go there are power, PTI and depot works that can't be completed. I'm sure it will get suggested again before the year is out though. |

They have bought more S stock than can be operated with the current signalling. (They should have been running under the originally proposed system that went with them by now.)
More trains will run once the new signalling is fully operational.
There are enough trains in the meantime to cover the returns to Derby to be retrofitted.

A defect - even a relatively minor one - will also get a unit withdrawn even if it has lots of hours left, because it ceases to be a "free" train if it costs money to fix it. |

The D stock do have opening windows, but it doesn't stop them being sweltering! Not sure if any S stock have suffered from broken air con, or whether this would be a reason to keep one out of service. A broken air con would not be enough to take a train out of service (although it may stop it from entering). Each carriage has it's own air conditioning unit, each with two separate circuits, so if one circuit goes down, there is still the other one that can do the work. Also as the carriages are fully open, if a carriage air con unit fails, there are still 6 or 7 dual units to take up the slack. Passengers would more than likely never notice that there is a problem. |

A defect - even a relatively minor one - will also get a unit withdrawn even if it has lots of hours left, because it ceases to be a "free" train if it costs money to fix it. All small routine servicing is still being done on the remaining trains, as are defect repairs. Major servicing has been stopped and i believe it is the countdown to this that is seen as the withdrawal marker. It is only major defects that would cause a train to be withdrawn early. |

Have all of the S7's delivered up to now entered service? When do deliveries resume? I can imagine that Bombardier are getting desperate to clear their yard of them as the class 345's are built.

As of today, there are only four S Stocks at Derby to be delivered (either via Old Dalby or direct to LU as the case may be).
However, also as of today, there are now 3 trains back at Derby for ATC mods - 2xS8 and 1xS7.

Will the few S8's which still have the red trim on the front valance be repainted to match the rest of the fleet while they're back at Derby? Seems like a good time to sort this inconsistency. Here's what I mean: Right = Red trim Left = Black trim  |

I wonder if the red topped valances are a legacy of the original units which had all red valances (and were promptly fixed after someone on here brought it to prjb's attention IIRC) |

Hahaha, how does that even happen. The all red front does look rather nice, but I'm so used to to the black now! |

Two newbies in traffic today (22/8) but somehow I doubt that this is their real first day in traffic.
Both at Farrindon.
21541/42 T 263 to HMS at 13:56
AND
21545/46 T 271 to BKG at 13:35

Latest rollout stats as of Saturday 03 September.
There are 118 S7s deployed on the network of which 65 S7s are deployed on the District "Main".
15 S Stock still to roll out on the District "Main"
14 D Stock to be removed.
In fact the total will only get to 126 this year as 7 S7s will start to go away for ATC fitment.
This may be my last update as I leave LU at the end of the month.

Thank you chaps. Will endeavour to add some value in the future. To answer the question about fitment. The current plan is for 4 x S8 and 6 x S7 to be away from the line though one of the S7s is making up for an S8 so the number in Derby or in transit will be 9 throughout most of the next 2 years. |
