As every Londoner knows, all tube lines were not created equal. There's a definite ranking of the lines you'd like to have to use, and those you'd like to avoid. So here's my own, totally unscientific (yet, I hope, reasonable) list of lines in order of usefulness.

Victoria

This isn't just because it's my daily commute (although I must say, in the nine months since I've been using it regularly, it's been pretty much rock solid), but it's because it's reliable and frequent. It probably helps that it's a single line with no branches (the only exception being the slight thinning of trains north of Seven Sisters as they peel off to the depot). Other things that help are the fact it's a relatively new line - only forty years old - and that the stations are spaced relatively far apart, making end-to-end journeys remarkably quick. Let's hope the current engineering works and the new stock (in service from next year, and hopefully a bit more roomy inside) don't cause any problems.

Bakerloo

The Bakerloo feels remarkably like the Victoria's older sister, partly due to its similar rolling stock. (It's much older, as it happens - the line celebrated its centenary a couple of years ago). However, it's also a single line (avoiding all those pesky problems with points) and it's mainly sheltered underground, so it seems to me - and I'm an infrequent user - that it's near the top of the list.

Central

Another old line, the Central manages to be remarkably useful despite having a fork at one end and a rather complicated loop at the other. However, its stock is pretty cramped - the line has some of the smallest tubes n the network - and although I commuted on it happily for six months, it doesn't quite reach the heights of the previous two entrants.

Piccadilly

Another line with branches, the Piccadilly does especially well given its length, with long extensions to Heathrow and Uxbridge (although the latter is a bit unreliable, from what I've noticed). I'm one of those people who'll save a tenner by taking it rather than the Heathrow Express, for example, and when I lived in the western half of Islington it was a pretty safe way to get back from the West End. However, it is pretty slow through the centre, with stops that are arguably too close together (the classic being Covent Garden's proximity to Leicester Square, exacerbated by the former's reliance on slow lifts), which keep it down at the current ranking, as does its extensive overground sections - always a problem if there's sufficient heat, rain or snow.

Waterloo & City

On the grounds of reliability alone, I reckon the Waterloo and City would score highly. Unfortunately, it loses out rather severely on the utility front, since it connects just two stations, closes in the early evening and isn't open at all on Sundays. It's also got the most uneven flow of any line I can think of, being full northbound in the mornings, with the reverse in the evenings, as commuters from the south west head back to their mainline trains.

Jubilee

The Jubilee is the newest line, with older sections being younger than the Victoria. However, a botched attempt to move to sophisticated signalling during the construction of the extended section seems to have doomed it to unreliability, and it seems to have quite low train frequency. This all knocks it along way down the list, which is a shame, because I like the noise of the gate thyristors of the trains, and it really should be a showcase for the system.

East London Line

This is a rather special case, since it's closed for engineering works until 2010, when it vanishes - it'll become part of London Overground (which, in the interests of sanity, I've excluded from this list, along with the DLR). Certainly, the current replacement bus services would be bottom of the list, but before its closure, I found the line reliable and friendly. Its use of Metropolitan stock meant the trains were spacious, and while train frequency was a little low (there was only one every six minutes) I still think it comes in as a fairly useful line.

Metropolitan

A long subsurface line, and the oldest (incorporating the original 1863 route from Baker Street to Farringdon), the Metropolitan seems to do surprisingly well, given the amount of its track exposed to the elements and the complexity of its north-western end. However, it does have issues, both out in the suburbs and when it gets interleaved with the other lines, which mean that, despite the spacious interiors, the line ends up pretty low in the rankings.

District

Another long subsurface line, the District has its fair share of branches, but mainly it loses points not for junction delays or complexity, but because it's so slow. The stations it shares with the southern edge of the Circle line all feel far too close together, so it takes an age to get anywhere. However, as with the Metropolitan, large carriages help it out, so it's saved from bottom place.

Northern

Ah, the Misery Line. No wonder it's down here. But what's this? A look at TfL's performance data seem to show more trains in service than any other line, and not too many delays. So why does the Northern end up all the way down here? Well, its complex layout is mostly to blame, causing both low train frequency on either branch (especially if you need to pass one of the link points at Camden Town or Kennington), while also letting delays affect either branch, if they're bad enough. Coupled with that are the short rolling stock - only six carriages, compared with a more typical eight for tube stock - and somewhat cramped interiors. (One can only be thankful that London Underground abandoned their usual colour-coding inside the train: all-black handrails would have just been even more depressing.) It drops into the last place for the deep tubes.

Hammersmith & City, Circle

I'm going to list these as a single line, because they share rolling stock, and they also share some of the same problems. However, in case you were wondering, the Circle really is deliberately listed last. The problem with it is simply that, except for two points, the line doesn't really exist: it's shared with the Metropolitan and District lines, and, as the name makes clear, has no terminus. This also means that there's nowhere to go when the service gets disrupted, and the usual outcome is that these two get sacrificed for the others. TfL plan to unroll the line somewhat in the next few years, running from Hammersmith around the loop once and then back to Edgware Road, which should help, but even so, the low train frequency (you can wait ten minutes for a Circle line train) and relatively small carriages (for a subsurface line, anyway) put the line at the bottom of the list.

So, that's the list. I should note that, even though it's last, the Circle still manages a reliability of over 85% and the average customer delay is about 10 minutes. I'd certainly usually choose it over buses, taxis or (horrors) driving.

I'd love to hear from more regular users of any of these lines if they have any comments.

Dan Hill posted an incredibly wide-ranging roundup of developments in transport informatics a couple of days ago on his site, and it's justifiably been widely linked to by the sort of people who care about such things. Of course, I'm one of them. I also tried to add a few things he missed in a rather dense, link-laden comment. Unfortunately, it was so link-laden that Typepad thinks it has to be comment spam, and it's now spent two nights in an approval queue, so I fear it's lost. Fortunately, I have my own blog, so here are some additional, somewhat London-centric notes.

Holisitic As Chris Heathcote noted when I mentioned the Guardian story on Helsinki's bus mapping, the statement that "every bus and tram is visible on a Google map" isn't true as of yet - the beta only covers a couple of trams and a few buses, if I'm remembering correctly. However, it's a promising start; London's iBus will generate similar raw data, and we'll see if the will's there to use it. Maybe someone should ask the mayoral candidates?

Here's a piece on the implications of Google Transit in the UK.

Rail The UK's National Rail maintains real-time arrivals and departures information, available on the web. It's probably unrealistic to map more than the trains going to a single terminus at the moment, because scraping doesn't scale, but that would be an interesting (hackday/barcamp?) project. A few Tube lines have similar information available, but that'll be harder to scrape into a single map.

Maritime There's a real-time high-resolution map of shipping in the San Francisco Bay available.

Walking Although not strictly informatics, on the subject of walking in London, there's a couple more initiatives; Legible London is a trial of maps for tube stations, bus maps and street pedestals, currently limited to the Bond Street area, but aiming at a unified signage standard for the entire city, and next week there's a Walk to Work day, encouraging people to walk, if not the entire distance, the first or last 30 minutes of their commute.

Edit: as often happens when I do something like this, it's now emerged. Thanks, Dan. I'll leave this up for posterity, though.

I try not to talk about politics too much here, but this article takes the biscuit. Here are some quotes from BBC News: Leafy Kensington shows its anger

Michelle Weininger is also desperate to deny that the campaign is about rich people making life easier for themselves.

"It is the politics of envy. It is totally wrong. This borough is very, very mixed, there are a lot of people on low incomes in north Kensington. They will all be hit by this."

How do people who are on low incomes afford cars? Here's a hint: they don't. The congestion charge means fewer cars on the road, and money for public transport, which adds up to more, faster buses. Which, you know, poor people actually use.

Mrs Weininger says: "If that dictator is shoving us onto public transport why is he not using it himself?"

Maybe if Mrs Wieninger ever used the Tube she'd notice that Ken Livingstone uses it to commute.

Gordon Taylor, chairman of the West London Residents' Association, is in possession of the facts on congestion charging and they have made him a very cross man.

"[The charge] is a blunder, which acts as the Berlin Wall and cuts communities in two."
