Expediency probably overruled such a plan ever becoming reality, but there's something to be said for avoiding all the congestion created by having one line with so many branches and intersections. The Bank branch takes longer to get to Kennington than the Charing Cross branch, though it's not clear on the Underground map. Things appear to get off to a good start with trains bypassing Mornington Crescent and heading straight for...
Euston. It's then less than a minute to get to King's Cross St Pancras.
That's less than one minute to get to the King's Cross St Pancras Underground platforms. Not the station ticket hall. Nor the two titular mainline stations. Embroiled in seemingly never-ending renovation, to get from St Pancras Underground station to St Pancras mainline station you currently have to walk ages to get into the open air, whereupon you find yourself next to King's Cross mainline station, meaning you then have to walk ages to get to St Pancras and so on. This visitor-unfriendly arrangement is, however, going to be at least partly curtailed in November this year when the pompous sounding St Pancras International opens for business.
Anyhow, what you can see of the Underground station looks very nice indeed, as you'd expect for a completely redone interchange. It's topped in terms of excellence, though, by Angel.
It's undoubtedly one of my favourite stations to date, chiefly by virtue of being so cool. The air conditioning is incredible. On the (as usual) boiling hot day I was travelling this stretch of the Northern line, I was more than happy to loiter a few minutes on Angel's platforms. Or rather, The Angel. It's never been called this officially, but colloquially the extra article has been around for decades, cemented in the popular consciousness by that edition of Forty Minutes from the late 80s, The Heart Of The Angel.
Back then the station, built in 1901, was one of the worst in the land: grotty, falling apart and plagued by lifts that never worked and a rather blinkered, flippant staff (at least, this was how they were depicted on camera). Shortly afterwards, however, it was shut, completely rebuilt and now represents surely one of the best stations on the network: clean, fresh and with the longest escalators in Western Europe.
Old Street, also built in 1901, is a complete contrast: it lives under a roundabout, with no buildings on surface level at all.
There's another abandoned station just before Old Street: City Road, closed in 1922 and all building work, including the platforms, subsequently removed.
Bits of Moorgate date back to 1865, but the whole place was done over in the 1960s to better incorporate that other bit of the Northern Line which doesn't exist anymore, but at the same time does: the bit from Moorgate to Finsbury Park. Now run by First Capital Connect, I don't know why this line isn't more used or better promoted. Maybe the answer's in the question: namely, it's run by First Capital Connect. There are about seven different entrances to Moorgate from the street. This isn't strictly one of them, but it's the nicest.
Bank station, or The Bank as train drivers stubbornly call it, is lacking a proper surface entrance like Old Street. But then it is right next to the Bank of England and Royal Exchange buildings. And it's part of that sprawling, complicated jumble of tunnels that joins it and Monument station into one uber-interchange the length of an entire street. And one of the exits is *inside* the Bank of England itself. To be honest, it's quicker to walk from one to the other above ground.
London Bridge is a bad interchange if you're trying to hop from the Northern to the Jubilee Line. There's no hopping involved, more like a long schlepp. Albeit in part along one of those magical moving walkways. The Jubilee platforms are way nicer than the stuffy, skanky Northern ones, but then since they were only built a decade or so ago that's no surprise. London Bridge itself is the oldest station in the city, dating back to 1838. It's got a really imperial entrance.
Borough, on the other hand, has a tiny front door and no escalators.
Apparently things used to be far worse, with - until recently - precious little having been done by way of renovation since 1890. It looks great outside, though, with that concrete roundel on the roof.
And so to Elephant & Castle, a right roustabout of a station with, if you choose to leave by one of the two entrances, no particularly striking buildingwork at all. Typically, this was the one I went for. The other entrance is your familiar Leslie Green-styled affair, of the kind I've already encountered at Kentish Town and Mornington Crescent. No photos of that, I'm afraid. Just this glum atrium.
The end was in sight. Here's Kennington again, this time with that classic dome in shot.
