On the Central Line drivers get "parallel running" training which is included in the annual refresher course, the trains have detonators in the emergency equipment cabinet should we ever derail and end up blocking the mainline which runs alongside the West Ruislip branch or at Ealing Broadway (they also mention Stratford but it would have to be a pretty spectacular derailment for us to end up blocking the mainline there). What are the detonators used for? Is it just 'audible warning', or is there something else more 'technical'?

It looks like there's an overhead wire in the photo for A - so somewhere like East Ham (sort of a penultimate station)?

Once again another newspaper report with an inappropriate photo Is that a 1972 stock train? And if so, does that mean it might be a Bakerloo line one?

That link doesn't seem to be valid any more; nor can I find the article on the railnews site. It's not on the Wayback Machine or in Google's cache. So - what's the information that doesn't want to escape?

A question on staff passes - I frequently see (because I use public transport a lot, not necessarily because it happens an awful lot!) staff using passes to let passengers through the gates when something doesn't work. I presume that that is permitted, and doesn't count as mis-use of the pass?
But what about PAYG Oyster users? They won't have touched in, so would normally get a maximum fare (whatever that happened to be. I'm sure that nowadays there are some clever behind-the-scenes things that can happen with refunding accidental maximum fare journeys, but how does that work? And what should a normal passenger do if their Oyster fails, they're let through the gates, and they don't get an automatic refund - how would they go about proving that they started their journey where they claim they would? (If they even noticed the extra charge, that is!)

The Bakerloo probably holds that record in London, but 1938 stock still works on the Isle of Wight "Island Line". Which answers the thread title as well, although not the more specific question in the first post (the Island Line can't really be considered as being on the Underground...).

Well, a quick Google search showed up a fascinating paper from 1969 on the engineering that went into the tunnelling of the Victoria Line. No mention of a record under Green Park, but there was a record set of just over a metre per hour when digging some experimental tunnels. See www.geplus.co.uk/ground-engineering-march-1969/38260.issue; the paper is Excavating for London's New Victoria Line, and it's well worth a read.

I don't have a good idea for C, but it's a station with a section of large glass panels.
Could it be Wood Lane?

Seeing as B has Oyster readers (the one second from the left numbered 51, in fact) I'm going to assume it's a station. It looks like newer gates on an older, but somewhat refurbished, station. It's vaguely reminiscent of Watford, so let's try a wild guess for Bushey.
Location C - would that be Willesden Green reversing siding?

Although it's apparently quite nasty, the Rotherhithe tunnel is open for pedestrians; it's southern exit is quite close to Rotherhithe station.
I'd say that the high-speed tunnel doesn't have a nearby alternative for pedestrians Similarly, the Overground south of Imperial Wharf doesn't have an associated pedestrian bridge as far as I can tell, and the District/Overground south of Gunnersbury is further from Key Bridge than some others.
However, although it's a walk, it's not really too far to walk from Canning Town to Island Gardens, through the Greenwich foot tunnel, then back up the peninsula to North Greenwich; certainly doable if you want a 'free' journey. Although if I'm suggesting that, Tower Bridge is reasonably close to Wapping & Rotherhithe...

For example, Hitchin to Cambridge is a double-track railway with no realistic passing facility. Well, that's not entirely true. It's not happened frequently, but I have been on a few trains (normally coming back from Cambridge) that passed the slow at Royston. It did cause a bit of confusion to the passengers on the Cambridge-bound platform when we pulled through - and occasionally stopped without opening the doors - from the 'wrong' direction. So if the will is there, it's possible. (On one occasion, the slow train pulled off before we'd passed - no idea why, but it was a tad annoying to be stuck behind an all-stations until Hitchin...)

If you count Bank as including Monument, then I could easily see Waterloo & City to Circle/District lines being quite a walk.
(And, by walk, do you mean physically have to put one foot in front of another - because the travelator at Waterloo means you don't 'walk' as far!)

TfL have at least put all of this information online: Apple PayThe 'convenience' over Oyster is that there's no topping up, which is helpful. That said, the first few times I tried Apple Pay on TfL it didn't work at all. Personally, I find contactless and Apple Pay to be about the same amount of time to touch in/out, but that Oyster is noticeably faster.

Well, an anagram solver finds quite a few 7-letter words (I know, it's cheating!), including a few place names and so on. But the (5-letter) word I did find on my own is "Train"...

But what will they call the next project which extends the Metropolitan Line? Since this is the first extension of the Metropolitan Line in its history (the Stanmore branch was opened by its predecessor, the Metropolitan Railway, shortly before it became a mere "Line"), I think we can safely put any thoughts of further extensions on the "not in our lifetime" pile. Umm - the line north of Baker Street was the original "Extension Line", opened in many stages. The main line ran from Paddington to Farringdon. Although if you're talking about the LPTB and later "line" then the only extension would be the quad-tracking.

Following on from the suggestion about inter-running being made easier if the four-rail system was abandoned, I thought I post some of my thoughts on the subject.
Four rail has a number of advantages over three rail. You can isolate running mechanisms from powering mechanisms, which should reduce complexity. I'm wondering if this makes it 'safer' - by enabling the train body to be an "earth"? Also, there's the ability to have simpler signalling mechanisms - no need for audio-frequency AC systems if the power return isn't in the running rails. And with each rail having a lower potential difference from ground, it should be overall safer.
Inter-running is also harder than just similar electricity delivery. There's signalling, as norbitonflyer mentioned, and loading gauge works both ways. I don't think that all Tube stock is safe to run on mainline metals even without signalling or power considerations; there's lots of 'stuff' that might get in the way - either on the train or on the track.
Does anyone know if the bogey positions on Tube stock are safe for UK tunnels? Would the ends of the cars always be clear of the walls?

South Harrow sidings? After all, there's been some space recently freed up there. And it might just prove that a subsurface stock of at least some kind can actually run on the branch!

Was once on a fast, non-stop to Cambridge which 'called' at Welwyn Garden City - for about 2 hours. It took that long to coral the horse, apparently...
And I've been on fast non-stop Cambridge to London Kings Cross services that called at the 'wrong' platform at Royston as well.

Destination code 609 "Circle Line outer rail from Ealing Broadway" is available. There are now scheduled workings from Acton Town to Barking via Edgware Road; Acton Town to Edgware Road via Kings Cross and Victoria; Ealing Broadway to Edgware Road. So - if all of these are Outer Rail, does that mean there's a service that calls at Edgware Road twice in one trip that hasn't come through Wood Lane? I could see that, actually - basically 'replacing' the Hammersmith-to-Paddington via Wood Lane section with something originating at a different depot. Are there equivalent workings from Neasden depot down through Baker Street, thence on round the eastern neck of the Circle all the way back to Edgware Road? Interestingly, a couple of weeks ago I was on an actually circular Circle Line service - went from St James's Park to Baker Street via High Street Kensington and the outer platform at Edgware Road. Was this a standard code, or had it just been done for the engineering works that day?
