I'm surprised that the biggest revision to tube trains since 1938TS does not warrant a prototype build for trial. There must be total confidence in computer simulations these days. Have Siemens experience with heavy rail builds of wheel-less cars? I know there have been bogies shared by adjoining cars, but how do wheel-less cars connect to adjoining cars to share the weight on bogies? Tramways often use no-wheel cars these days, but these are for light rail duties. I have asked before without response: what are wheel-less cars called? Yes, the previous biggest step change to rolling stock design was the 1992 stock, which of course had the 1986 as full working prototypes. Hopefully, the NTFL will turn out better than the poor 92's!

I'm sure online there is a list of shafts and what they are for. Not doubting you, but would there be a danger of misuse if that information was in the public domain?

"Fire alert in the control room" would be a lot more useful information to give, even if it's technically less precise. Agreed - and it stops the punters coming up with “what’s Upminster got to do with it?” 😂

Can anyone explain this?
London Overground: No service between Stratford and Richmond / Clapham Junction and Gospel Oak and Barking due to a fire alert at Upminster.

Whilst the news about Routemaster operation is relevant to TFL’s finances, continued discussion about buses is beyond the scope of the forum.

The Hatton Cross extension was cut and cover in 1975! It was, but that was the best part of 50 years ago - hardly today!

... And there we have a clear example of that very confusion! I don't think that's confusion. There are many reasons why you couldn't build LU as it is now, today. Political Financial We've already got oneWell, you did start off the thread! 😁

Article and photos of a walk through the tunnels (2003) on abandonedstations.org.uk Here - DraytontoFinsburyYes, I think that adds weight to the idea that those tunnels were not used to remove rails from the Victoria line.

I thought the Drayton Park tunnel mouths were sealed many years ago. How would trains from the Vic have been able to get to Drayton Park? We need the Underground News article! I'll see if I can track it down. Maybe @reganorak can help with finding something?

Yes, and that tunnel is blocked off at the Finsbury Park end just before what is now the crossover from the southbound Vic to the southbound Picc. With my mod hat on, I’ve been instrumental in dragging this thread off topic, so I’ll split it tomorrow.
That ties in with what I recall. My memory is slightly vague, but I think the north end of the tunnel ends in a solid wall. Certainly I entered it side-on via a cross-passage from the s/b Victoria Line tunnel. Wish I’d had a bit more time, though I certainly had (made!) time to walk all the way to Drayton Park and back! Bet that was quite an eerie experience, with the noise and air-rush of nearby trains!

Was that around the time when the Ffestiniog railway took the rails from Drayton Park depot?

Interesting, because my recollection is that access from Finsbury Park (tube platforms) to Drayton Park was cut before the Vic line opened. The only link was to the BR station, which was used for stock transfers to and from Highgate (latterly Neasden). The tunnel mouths were demolished and landscaped. It is, however, possible to walk through the n/b former tunnel from the Finsbury Park end, and emerge at Drayton Park in the vicinity of where the tunnel mouths were. The gate is narrow and at right angles to the tunnels, so I’m not sure what any benefit would be of removing rails this way. Could someone have added 2 + 2 and come up with 5? Yes, and that tunnel is blocked off at the Finsbury Park end just before what is now the crossover from the southbound Vic to the southbound Picc. With my mod hat on, I’ve been instrumental in dragging this thread off topic, so I’ll split it tomorrow.

No, is the simple answer, I dread to think how long the list of reasons why not would be , but you could start with curved platforms and step free access. Neither curved platforms nor step-free access are engineering obstacles. It would, in fact, be easier to build the SSR today, than it was at the time; a result of years of experience and technical progress. People always confuse politics with physical fact. Cut-and-cover construction in a built-up area would never be permitted today!

I thought the Drayton Park tunnel mouths were sealed many years ago. How would trains from the Vic have been able to get to Drayton Park? This was at the time of the Victoria line opening, so before they had got around to sealing the tunnels. And there must still have been some access for Metronet to remove redundant rail more recently!

Taken from another thread:
Before the Victoria line upgrade, Metronet removed redundant rail through this same tunnel connection to Drayton Park for disposal by road, so it must have still existed maybe 15 years back.

MOD COMMENT:
The above post is a reminder as to why it’s important to think before posting.
Also, a reminder to think about the tone of our posts. I’m sure that in the current climate, there are quite a few “job centre rejects” through no fault of their own. It’s not the first time that posting tone has been mentioned either - just saying.

A name that's been suggested elsewhere for the Watford DC is resurrecting the old NSE-era "Harlequin Line" name, which I don't think is a bad idea. Was it ever an official name though? I do recall seeing it on some publicity / timetables, but never heard it referred to as that in the general public domain.

Things are getting busier... see tweet: Not sure this is entirely accurate to be fair, the Picc's not had the best of evenings, with delays due to an earlier customer incident. Not sure if the service was partially suspended at all at any point, but having just checked the service status, it's still recovering now. Having looked at the tweet, my guess is this was at the height of the disruption from said customer incident, but I could be wrong. The service was suspended from Hyde Park Corner to Hammersmith.

I think the 4th rail was retained (in working condition) between Harrow and Watford until at least 1984, because after Bakerloo services were cut north of Stonebridge Park in 1982, there was an ongoing discussion about reintroducing the service. In the end, it was decided that the Bakerloo would not go beyond Harrow and Wealdstone.
There is a rumour that a 1959 stock made it to Watford Junction (after the Bakerloo service had ceased) - no idea how true it is, but it's been mentioned in various places.

Excellent! It's nice to see some sense finally being spoken on the issue by someone in charge. Let's hope they stick with the names (West London line, Watford DC, Goblin etc.) that existed prior to them being taken over by LO. I doubt that Watford DC will be used, although it would be the name of choice for many of the enthusiasts!

I am thinking about the Bakerloo / LO north of Harrow and Wealdstone, and the Northern City line, both of which had the 4th rail dropped to track level after ceasing to be operated by London Underground trains. I understand that completely removing the 4th rail would be difficult and expensive, but why not just leave it as it was (at the same height as the 3rd rail)? rail on sleepers would be relatively low, clear of train borne obstructions, require less maintenance (pots etc) ps. negative rail is not same height as positive rail. Thanks - forgot that 3rd / 4th were different heights!

To answer the question originally posed by spsmiler, there isn't a lot of verifiable information available online, but consensus seems to be around 12 feet or a rather alarming 3.7 meters. That is alarming. Even a gas meter is only about 30cm (a foot) in it's largest dimension. 12 gas meters wide - a non-standard unit of length if I ever heard one!

I seem to recall reading that Archway was the last deep-level station to retain tungsten lighting, surviving until 1980. Were there any other stations that retained it until relatively late, or was Archway an anomaly?
Apart from the (new in 1967) northbound platform at Highbury, the Northern City Line remained completely tungsten lit until it closed, pending transfer to BR, in October 1975.
