This map shows what London’s tube network would look like without any actual tube lines

What. Image: TfL.

Well. This is one of the weirder tube maps I’ve seen of late. And believe me, I see a LOT of tube maps.

It’s so weird, in fact, that it’s weird in two distinct ways. Firstly it’s geographically accurate: rather than adopting the Harry Beck-style diagram we all know and love, it uses a map of the London boroughs to show where the lines actually go.

Secondly, it shows just four lines: the Metropolitan, Hammersmith & City, Circle and District. Effectively, it’s the lines which share track with the inner circle.

What’s really weird about it, in its way, is that it’s actually the work of Transport for London (TfL), rather than a bunch of nerds like, well, like me.

There is a method to this madness. Not all tube lines are actually tube lines: technically, that label should only apply to those which run through tunnels bored deep underground.

These others are technically “sub-surface” lines. They’re the oldest part of the network, built through the relatively primitive method of digging trenches, sticking tracks in them and then building over the top again. These have slightly bigger trains and, generally, better air-conditioning, too.


I’m not sure why TfL felt moved to produce this as a separate map. Perhaps it’s a useful aide-memoire for those working on the network. Perhaps it’s to show which stations are reachable directly via lines serving the inner circle, for some reason. Or perhaps it’s just because they know that someone like me would inevitably write about it, and they like the attention. Who can say?

One thing we can say, though, is that there is a weirdly long gap between Kings Cross St. Pancras and Farringdon, and they should build a station at Mount Pleasant to plug it.

You can see the whole thing here. Hat tip: Diamond Geezer.

UPDATE: Okay, guys, I’m going to level with you: I wrote the above, very quickly, on Friday afternoon in about three minutes because I thought there might be traffic in it. (Don’t judge me, you clicked, didn’t you?) I may not have dedicated quite the investigative energies to this story that a matter of such importance clearly deserves.

Anyway. Diamond Geezer has been in touch to point out that TfL have actually explained why the map exists. It’s to show the scope of this project:

We are transforming the Circle, District, Hammersmith & City and Metropolitan lines. When the work is completed in 2023, increased capacity and boosted reliability will make journeys faster and more comfortable.

Because these lines share a lot of track and infrastructure, they are being modernised under a single combined and integrated project, Four Lines Modernisation (4LM).

The 4LM project will involve new trains, tracks and signalling, allowing shorter journey times a 33 per cent increase in peak-hour capacity on the sub-surface network. Which, since it makes up 40 per cent of the network, is a pretty big deal.

Cool.

CityMetric is now City Monitor! Come see us at our new home

City Monitor is now live in beta at citymonitor.ai.

CityMetric is now City Monitor, a name that reflects both a ramping up of our ambitions as well as our membership in a network of like-minded publications from New Statesman Media Group. Our new site is now live in beta, so please visit us there going forward. Here’s what CityMetric readers should know about this exciting transition.  

Regular CityMetric readers may have already noticed a few changes around here since the spring. CityMetric’s beloved founding editor, Jonn Elledge, has moved on to some new adventures, and a new team has formed to take the site into the future. It’s led by yours truly – I’m Sommer Mathis, the editor-in-chief of City Monitor. Hello!

My background includes having served as the founding editor of CityLab, editor-in-chief of Atlas Obscura, and editor-in-chief of DCist, a local news publication in the District of Columbia. I’ve been reporting on and writing about cities in one way or another for the past 15 years. To me, there is no more important story in the world right now than how cities are changing and adapting to an increasingly challenging global landscape. The majority of the world’s population lives in cities, and if we’re ever going to be able to tackle the most pressing issues currently facing our planet – the climate emergency, rising inequality, the Covid-19 pandemic ­­­– cities are going to have to lead the way.

That’s why City Monitor is now a global publication dedicated to the future of cities everywhere – not just in the UK (nor for that matter just in the US, where I live). Our mission is to help our readers, many of whom are in leadership positions around the globe, navigate how cities are changing and discover what’s next in the world of urban policy. We’ll do that through original reporting, expert opinion and most crucially, a data-driven approach that emphasises evidence and rigorous analysis. We want to arm local decision-makers and those they work in concert with – whether that’s elected officials, bureaucratic leaders, policy advocates, neighbourhood activists, academics and researchers, entrepreneurs, or plain-old engaged citizens – with real insights and potential answers to tough problems. Subjects we cover include transportation, infrastructure, housing, urban design, public safety, the environment, the economy, and much more.

The City Monitor team is made up of some of the most experienced urban policy journalists in the world. Our managing editor is Adam Sneed, also a CityLab alum where he served as a senior associate editor. Before that he was a technology reporter at Politico. Allison Arieff is City Monitor’s senior editor. She was previously editorial director of the urban planning and policy think tank SPUR, as well as a contributing columnist for The New York Times. Staff writer Jake Blumgart most recently covered development, housing and politics for WHYY, the local public radio station in Philadelphia. And our data reporter is Alexandra Kanik, whose previous roles include data reporting for Louisville Public Media in Kentucky and PublicSource in Pittsburgh, Pennsylvania.

Our team will continue to grow in the coming weeks, and we’ll also be collaborating closely with our editorial colleagues across New Statesman Media Group. In fact, we’re launching a whole network of new publications, covering topics such as the clean energy transition, foreign direct investment, technology, banks and more. Many of these sectors will frequently overlap with our cities coverage, and a key part of our plan is make the most of the expertise that all of these newsrooms combined will bring to bear on our journalism.

Please visit citymonitor.ai going forward, where you can also sign up for our free email newsletter.


As for CityMetric, some of its archives have already been moved over to the new website, and the rest will follow not long after. If you’re looking for a favourite piece from CityMetric’s past, for a time you’ll still be able to find it here, but before long the whole archive will move over to City Monitor.

On behalf of the City Monitor team, I’m thrilled to invite you to come along for the ride at our new digs. You can follow City Monitor on LinkedIn and on Twitter. If you’re interested in learning more about the potential for a commercial partnership with City Monitor, please get in touch with our director of partnerships, Joe Maughan.

I want to thank and congratulate Jonn Elledge on a brilliant run. Everything we do from here on out will be building on the legacy of his work, and the community that he built here at CityMetric. Cheers, Jonn!

To our readers, on behalf of the City Monitor team, thank you from all of us for being such loyal CityMetric fans. We couldn’t have done any of this without you.

Sommer Mathis is editor-in-chief of City Monitor.
