The analogy was made elsewhere a while back that if cars had followed the same trend as trains for weight and power consumption, the average Ford Fiesta would now weigh 7 tonnes and do 3mpg. 7.4 tonnes greater than a Q35... that really does put it into perspective. The Q stock was considered to be a heavy train and I never thought we would ever see trains on the Underground again which would be anything near that weight, let alone exceed Q stock tonnage. I am going to make a point of going down the subway under the west and eastbound Circle and District lines at Embankment when the S7s start to appear on the Circle, the S stock rumble and boom is going to be something to be heard when it runs overhead.  |

2 x S7s, at full pelt in the crush hour, passing each other as they cross the Thames twixt Gunnersbury and Kew will sound interesting. I wonder how soon thereafter, the engineers will start looking for structural faults on that bridge?? Will there be any red faces if speed or especially weight restrictions have to be imposed??

I wonder how soon thereafter, the engineers will start looking for structural faults on that bridge?? Will there be any red faces if speed or especially weight restrictions have to be imposed?? Unloaded 2 X S8 = 3 X D78 D stock 144 tonnes with 827 passengers, the TfL stated max capacity, (at my estimate 75kg each person on average) gross weight 206 tonnes. S7 stock 214 tonnes with 865 passengers has a gross weight 278 tonnes. A D78 fully loaded is less than an empty S7. 2 fully loaded S7s compared to 2 fully loaded D78s on that Thames bridge would increase the weight load by 35%. History in reverse as a new, modern, aluminium bodied R stock fully loaded was the same weight as an empty Q stock. With the S stock the elecy bill is going up for a start as well as the budgets for track and related infrasructure. |

Speed restrictions, you say castlebar?
Far as I can tell the parts of the system are currently running with slower station-station times, lower frequencies and shorter trains than 90 years ago.
I doubt the 'upgrade' will achieve anything better than whats been achieved at some point in the past.

While it can't be denied that an S stock train is heavier than the trains it replaces, there is no individual axle load in excess of the highest axle load on A, C or D stock. |

While it can't be denied that an S stock train is heavier than the trains it replaces, there is no individual axle load in excess of the highest axle load on A, C or D stock. The heaviest axle loads increase on all 3 sub service stocks. The A stock driving motor car being replaced by the S8 increases by 1.5 tonnes (over 4 axles etc.). C stock DM to S7 DM increases by 1.7 tonnes and the eco lightweight D stock DM to S7 increases by 6 tonnes. |

Ahh remember the Q31/35 were built from lightweight construction with the trailers on 22 tonnes each roughly. Compare the S stock to the O/P stock with 3 tonne Metadyne machines - they had regenerative braking too..... Weight wise the Metadyne machine was not that heavy as it did control 2 motors cars, as opposed to 2 sets of PCMs. |

Explain then why a metadyne battery loco was around 2.5 ton heavier than a non metadyne from the same batch.

Just thought to let peeps know 5596-6596 is alive and well plying its trade That's good then, shaln't be long before 5595 gets taken away from Acton, because I imagine thay've stripped it of any useful parts it could provide. |

I doubt the 'upgrade' will achieve anything better than whats been achieved at some point in the past. Apart from air conditioning. I don't care if it makes all the trains heavier and slower. It'll change a hot sweaty miserable journey into something halfway acceptable. ATM I crawl along in London traffic in my car and the air con uses up a lot of extra fuel as a result. I don't get hot and I don't get angry. Well worth the expense in my book. I wouldn't buy a car without it nowadays for London or any other major city driving. |

I had a very interesting conversation with a Met driver the other day. He told me that with the S stock coming in, we could expect all the As and Cs to be gone by this year, early next year at the latest, and the Ds to be gone by the end of next year...

That sounds a bit quick. Are deliveries going to speed up?
There are still 133 S Stock to deliver. At the current rate of six trains per month. It will take two years to complete delivery.
What is happening during the five ring circus, will deliveries continue or will they concentrate on those already delivered?

I can't see the C stock and D stock going that quickly. The S7 build is not that advanced!

C's gone this year !?!?! You must have come across Hans Christian Train Op !!! ditto D's next year! |

According the wikipedia, the first serviceable C Stock will be withdrawn on the 21st July (Am I alone in thinking this would be unlikely)?

The 3 current S7 deliveries will continue to be used on infrastructure testing (signal sighting, camera positioning), driver training etc. for a while yet. The S7 'preview service' is an additional working and will not directly replace a C Stock. Until the infrastructure towards Barking is commissioned towards the end of the year I can't see any C Stock going until then. |

Unless they're referring to 5595, I also have doubts over the claims.

Unlike the A & D stock I will be pleased to see these units go.

I'm still thankful that provision was made for Met end user needs, in that there's some transverse seating. As long as there's transverse seats on a Met train, I will use it (Despite going against the teachings of A Stockology). Shame about the D Stock, which is one of the most reliable on the system. Everyone has already had their dig at the C Stock (save for the elusive prjb).

C Stock can't go soon enough! I'm quite tolerant of most trains, but C Stock is the only one I truly hate. Gloomy trains, ridiculously stale air, all the extra vibration...
I commute daily over the northern bit of Inner Circle and always take the Met instead.

I commute daily over the northern bit of Inner Circle and always take the Met instead. It's very noticeable how busy Pfm 3 at Baker Street is now and not only during the peak times. Whereas everyone used to go to Pfm 5, they now all seem to go to Pfm 3 as the service is more reliable and air conditioned. When the Met only ran to the city in the rush hours Pfm 5 was always much busier than 3. Another interesting point is last Thursday when the humidity was at its highest, there was an empty A stock in Pfm 1 at Baker St and everyone packed onto the S coming out of the city, normally more people get on a Baker St starter as they get a seat. |

Now, as MetControl reported in the "C Stock Formation" board, either 5532 or 5575 will be scrapped from Northwood in the near future. This is as a result of a 'side-swipe' in Hammersmith Depot. The rest of the fleet should be leaving from Acton unless otherwise stated.
5595 is still extant at Acton Works.
