TfL has quietly released a map of the London Overground in 2026

Rejoice, map geeks of old London town! The capital’s transport authority, TfL, has quietly released a lovely new map showing where it expects its heavy rail London Overground Network to take you by 2026.  

The map was released as part of a consultation on its plans to extend the Gospel Oak-Barking line to Barking Riverside, the site of a big new housing estate. (They're planning to put some houses there, and plans to extent the DLR have fallen by the wayside, so the thinking is they might as well send some big trains there instead.) Here’s a map:

But the network map which accompanies this consultation contains all sorts of other interesting factoids about what TfL think the future looks like. You can examine the whole thing here, but it’s a bit on the unwieldy side for a family website like ours, so we’ve plucked out a few of the more interesting details below.

More lines!

The map shows all the bits of the rail network whose operators will be answerable to the city’s government, rather than the national Department for Transport. That includes the existing Overground network; the West Anglia suburban lines into Liverpool Street (which TfL is taking over some time next year); and Crossrail (which is currently under construction, and which neatly ties the rest of the network together).

Oddly, though, it chops off the outer extremities of Crossrail. That sort of makes sense when it comes to far distant Reading and Maidenhead, but it’s a bit odd that it excludes two stations (Harold Wood and West Drayton) which are actually within the city boundaries.

More changes!

Just to annoy everyone, the new Overground network crosses the existing one in no fewer than four places, without stopping once.

This is probably why the map has, for the first time, shown interchanges which you can make if you’re happy to walk along at street level for a bit.

More excitingly, it also includes an entirely new station at Old Oak Common, where you’ll be able to change from the Overground to Crossrail (suggested branding: “Old Oak Common: The Stratford of West London”). This could one day be an outer London stop on the High Speed 2 line to the north, too, which would make it easier to get from Heathrow to points north.

Sadly it still doesn't point out that Camden Road is a mere five minute walk from Camden Town tube station. Can’t have everything.

More orange!

All this is very interesting, if you're into such things (and we obviously are). But it's also oddly unwieldy.

By 2026, if all goes to plan, the Overground network will have six entirely separate lines, some of which have up to four branches. Yet it continues to colour them all in the same shade of Sunny Delight orange.

These lines go to such a wide range of destinations; often cross without interchanging; and one branch right out in the far east never connects with any of the others.

Given all that, could we maybe look into differentiating them through some kind of colour scheme, perhaps? Like, y’know, every other urban rail network in the world?

More TOWIE!

There's one more oddity. Far out in the wilds of zone 6, where east London drains off into Essex, London Overground is also taking on a three-station, single track branch line on which you can get two trains an hour from Romford and Upminster and back.

There's a long and complicated reason for this, but it basically amounts to "nobody else wants it". It's too small to be part of Crossrail, but doesn't connect to anything else, so TfL are stuck with it.

If you do fancy making a trip to Emerson Park halt, we recommend you do so in December: the giant houses in the neighbouring estate tend to go absolutely nuts with their Christmas lights.

 
 
 
 

Coming soon: CityMetric will relaunch as City Monitor, a new publication dedicated to the future of cities

Coming soon!

Later this month, CityMetric will be relaunching with an entirely new look and identity, as well as an expanded editorial mission. We’ll become 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 coming soon from New Statesman Media Group. We can’t wait to share the new website with you, but in the meantime, here’s what CityMetric readers should know about what to expect from 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 going to be 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 will be 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’ll 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 this fall, 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.

City Monitor will go live later this month. In the meantime, please visit citymonitor.ai to sign up for our forthcoming 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 forthcoming digs. You can already follow City Monitor on LinkedIn, and on Twitter, sign up or keep following our existing account, which will switch over to our new name shortly. 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!

In the meantime, stay tuned, and thank you from all of us for being a loyal CityMetric reader. We couldn’t have done any of this without you.

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