You could run trains at exactly the same frequency (if you had a few more), so as far as Brixton is concerned, it wouldn't be any different. Or am i being stupid? Extending the line and adding more stations increases the number of passengers that the line must carry. Right. To ensure that loadings remain even, train frequency must be increased to compensate, which is the problem at hand. Okay. I don't understand that - why does the frequency have to increase? Because, given that the vast majority of passengers are travelling to the central area (say Victoria - KXSP), the passengers from the new, extension stations are using capacity in the central area which isn't available. Aaah! I see. Yes, that's rather obvious when you put it like that, sorry. The Victoria line is essentially full at the moment. Next question, then - how come? It has a pretty decent 28.5 tph, it's the shortest proper line in the whole network, and all but one of its stations are on other lines as well! For northbound trais to be be full at Victoria, Brixton, Stockwell, Vauxhall and Pimlico would have to be generating as many passengers as all the Northern line stations from Morden to Kennington put together, or the Piccadilly line stations from Cockfosters to Caledonian Road. I don't know those areas terribly well, and i realise that at least some of them are very densely populated areas, but that seems quite surprising. Is it because there are few people getting off the line before central London? I guess a lot of Picc passengers switch to the Vic at Finsbury Park, and perhaps Northern passengers to the Vic at Stockwell! Or is the Victoria line picking up a lot of passengers from the suburban railway network? tom -- Who would you help in a fight, Peter van der Linden or Bill Gates? |

Or is the Victoria line picking up a lot of passengers from the suburban railway network? Well, according to the London Transport Strategy, in the morning peak, the Victoria line is currently "very crowded" (i.e. operating in excess of or near to planned capacity) northbound between Victoria and Green Park, and southbound between Finsbury Park and King's Cross, and Euston and Warren Street. Between Stockwell and Victoria it's just "busy" northbound. The Northern line is "very crowded" northbound from Clapham Common to Stockwell, after which it becomes "crowded" from there to Kennington, suggesting a significant number of passengers transfer from the Northern to the Victoria at Stockwell. As I'd expect, the "very crowded" section north from Victoria indicates that the line picks up an extremely high number of passengers from the rail terminus, and it's on this Victoria - Green Park section that capacity has been reached. Adding any stations further south would mean those rail transfer passengers being left behind on the platform. Unfortunately the diagrams in the Transport Strategy don't go beyond Finsbury Park - but the Piccadilly southbound is at capacity already at least between Finsbury Park and KXSP. Incidentally, 2010 projections have the eastbound Piccadilly line operating at capacity all the way from Barons Court to Hyde Park Corner (presumably by which time, some passengers are so fed up they just get off and get the bus!). -- Dave Arquati Imperial College, SW7 www.alwaystouchout.com - Transport projects in London |

Northbound trains usually have a little spare capacity until they reach Victoria, at which point they invariably fill fuller than is comfortable! I don't know at what point you begin to be able to breathe again, but I assume at Kings Cross! For northbound trais to be be full at Victoria, Brixton, Stockwell, Vauxhall and Pimlico would have to be generating as many passengers as all the Northern line stations from Morden to Kennington put together, A great many people change on to the Vic at Stockwell, probably because it is a great deal quicker across London than the Northern Line is, and if you are going to (e.g.) King's Cross, it's enough quicker to make changing worth while. You can usually get a seat at Brixton, unless a train has been cancelled, but in peak hours it's often standing-room only after Stockwell. -- "Mrs Redboots" http://www.amsmyth.demon.co.uk/ Website updated 3 April 2005 |

Or is the Victoria line picking up a lot of passengers from the suburban railway network? I guess it could be a factor. If I were commuting up through Brixton to Victoria and then needed the tube, I'd be inclined to get off at Brixton and join the Victoria Line there rather than go through the squeeze at Victoria. I'm not sure how fast the Balham - Stockwell route is but there could be passengers using that as an alternative. Commuter trains at Vauxhaul have often shed quite a few there at peak hours. |

If I take the tube from King's Cross to the office in Westminster I take the Victoria Line to Green Park and the Jubilee from there to Westminster but I come back via St James Park and Victoria so I'm more likely to get a seat. For preference I cycle as it's quicker and more predictable. When I worked in Westminster I normally walked to Victoria. Actually, I usually caught a bus home - where I live, I have the option of two trains, a tube or a bus from Victoria. -- "Mrs Redboots" http://www.amsmyth.demon.co.uk/ Website updated 23 May 2005 |

Since Brixton's NR service is pretty feeble, IME far more people (myself included) join the Victoria Line at Brixton from buses. It acts as a (pretty unpleasant) parkway station for a huge area of tubeless London, and I think is the busiest station outside Zone 1. If only it had a decent bus interchange (like Hammersmith)! As Annabel and others have already pointed out, it also takes a large amount of the Northern Line's central London passengers at Stockwell! |

If the CRT ever becomes a reality, they are going to HAVE to make a decent bus interchange, or it will be even more impossible than it already is. I would rather get the NR service if possible to Victoria, but the NR station is considerably more unpleasant than the Victoria Line one, so you have to time it right! I have to admit that one thing Ken Livingstone has done is to increase the number of buses southbound from Brixton in the rush hour. Time was, if I wanted to go to Streatham for 18.45 (which I do about once or twice a week), I had to leave the house at 17.45 if I were to have any hope of getting on a bus, and usually walk up to the stops by Brixton Police station to have any hope of getting on a southbound bus. These days I normally can get on the first bus that comes, and failing that, the second. -- "Mrs Redboots" http://www.amsmyth.demon.co.uk/ Website updated 23 May 2005 |
