The Delhi Metro: How do you build a transport system for 26m people?

“Thou hath not played rugby until thou hath tried to get onto a Delhi Metro in rush hour,” a wise Yogi once said.

If you’ve never been on New Delhi’s Metro, your mind might conjure up the the conventional image of Indian trains: tawdry carriages, buckets of sweat, people hanging out of windows and the odd holy cow wandering around for good measure.

Well, no. The Delhi Metro is actually one of the most marvellously sophisticated, affordable, timely, and practical public transportation systems out there. On a 45C day in the Indian summer, many a traveller has shed tears of joy on entering the spacious, air-conditioned carriages.

Above ground, Delhi is a sprawling metropolis of the scariest kind: 26m people, three times the population of London, churn and grind through Delhi itself.

The National Capital Region, an area which includes Delhi and its surrounding satellite cities – now victim of its never-ending urban sprawl – has an estimated population of almost 50m. So how do you tie such a huge population together?

Motorised vehicles won’t do it alone. For one, air pollution is a horrific problem in Delhi, as it is across India. Last November, the government declared a state of emergency when the Indian capital was engulfed by a toxic, choking fog so thick that you could barely see several metres in front of you, drawing allusions to the great Victorian fogs in London.

Then there’s Delhi’s famous traffic. Twenty-five years ago, the travel writer William Dalrymple observed that you could reduce the Delhi’s road laws to one simple idea: the largest vehicle always had the right of way. The traffic has tamed somewhat in the 21st century, but the number of vehicles has multiplied again and again, and it’s not uncommon for people to be stuck in four-hour traffic jams when they try to traverse the mighty city.

Enter the Delhi Metro – a huge network of 164 over- and underground stations – and by any account, a titan of civil engineering and administration.

The numbers are simply colossal. Every day the metro serves on average almost 3m people. Annually, it carries around 1bn.

In a country where intercity trains still turn up a day late, the Delhi Metro is extraordinarily timely. On the major lines, trains will come every several minutes. The trains are extraordinary speedy, and you’ll reach your destination in a fraction of the time it would take for you to drive the distance.

The minimum fare is 10 rupees (12p); the maximum fare, to and from the airport, is 50 (60p).

Construction of the metro system began in 1998, with the first section completed in late 2002. Keen to avoid the catastrophic corruption and bureaucratic mismanagement which plagued eastern city of the Kolkata Metro, developers took advice from Hong Kong’s high-tech system There have been several stages of development to add extra lines; more is planned. By 2020, it is hoped that the 135 miles of line will have increased to over 300.  

One thing quite striking about the metro is its women’s only carriages at the rear and the front of the train, marked by pink signs. Sexual assault and harassment has been a horrific problem on Delhi’s transport systems. Women can of course go anywhere on the train – but men who violate the carriage system will have to deal with the scathing anger of the entire pink carriage.


One of the under-discussed impacts of widespread and well-used public transportation systems is their propensity to break down social and class barriers over time. As the London Tube began to be used more and more in early 20th century London, people from completely different walks of life and classes began to brush shoulders and share the same air.

The story is similar in Delhi. The necessity of the metro helps to break down old caste and class divisions. Of course, many elite Delhiites would not be seen dead on the metro, and choose their private chauffeur over brushing shoulders with the common man. But slowly and surely, the times are a changing.

What’s more, the Delhi Metro system is one of the greenest around. Six years ago, the Metro was the first railway system in the world to be awarded carbon credits from the United Nations for helping to reduce pollution in the capital by an estimated 640,000 tonnes every year.  

All praises sung and said, however, at peak times it’s less mind the gap and more mind your ribs – as a fifth of humanity seems to try to get on and off the train at once.

What other British cities can learn from the Tyne & Wear Metro

Ask any person on the street what they know about Newcastle, and they’ll list a few things. They’ll mention the accent; they’ll mention the football; they’ll mention brown ale and Sting and Greggs. They might even mention coal or shipbuilding, and then the conversation will inevitably turn political, and you’ll wish you hadn’t stopped to ask someone about Newcastle at all.

They won’t, however, mention the Tyne and Wear Metro, because they haven’t probably heard of it – which is a shame, because the Metro is one of the best things the north-east has to offer.

Two main issues plague suburban trains. One is frequency. Suburban rail networks often run on poor frequency; to take Birmingham for an example, most of its trains operate at 30-minute intervals.

The other is simplicity. Using Birmingham again, the entire system is built around New Street, leading to a very simple network. Actually, that’s not quite true: if you’re coming from Leamington Spa, Warwick, Stourbridge, Solihull or a host of other major minor (minor major?) towns, you don’t actually connect to New Street – no, you don’t even connect to the ENTIRE SYSTEM BUILT AROUND NEW STREET except at Smethwick Galton Bridge, miles away in the western suburbs, where the physical tracks don’t even connect – they pass over each other. Plus, what on earth is the blue line to Walsall doing?

But Newcastle has long been a hub of railway activity. Tragically, the north-east has fewer active railway lines than any other region of the UK. Less tragically, this is because Tyne and Wear has the Metro.


The Metro was formed in 1980 from a somewhat eccentric collection of railways, including freight-only lines, part of the old Tyneside Electrics route, underground tunnelling through the city centre, track-sharing on the National Rail route to Sunderland, and lines closed after the Beeching axe fell in the early 1960s.

From this random group of railway lines, the Metro has managed to produce a very simple network of two lines. Both take a somewhat circuitous route, the Yellow line especially, because it’s literally a circle for much of its route; but they get to most of the major population centres. And frequency is excellent – a basic 5 trains an hour, with 10 tph on the inner core, increasing at peak times (my local station sees 17 tph each way in the morning peak).

Fares are simple, too: there are only three zones, and they’re generally good value, whilst the Metro has been a national leader in pay-as-you-go technology (PAYG), with a tap-in, tap-out system. The Metro also shares many characteristics of European light rail systems – for example, it uses the metric system (although this will doubtless revert to miles and chains post-Brexit, whilst fares will be paid in shillings).

Perhaps most importantly, the Metro has been the British pioneer for the Karlsruhe model, in which light rail trains share tracks with mainline services. This began in 2002 with the extension to Sunderland, and, with new bi-mode trains coming in the next ten years, the Metro could expand further around the northeast. The Sheffield Supertram also recently adopted this model with its expansion to Rotherham; other cities, like Manchester, are considering similar moves.

However, these cities aren’t considering what the Metro has done best – amalgamated local lines to allow people to get around a city easily. Most cities’ rail services are focused on those commuters who travel in from outside, instead of allowing travel within a city; there’s no coherent system of corridors allowing residents to travel within the limits of a city.

The Metro doesn’t only offer lessons to big cities. Oxford, for example, currently has dire public transport, focused on busy buses which share the same congested roads as private vehicles; the city currently has only two rail stations near the centre (red dots).

But it doesn’t need to be this way. For a start, Oxford is a fairly lateral city, featuring lots of north-south movements, along broadly the same route the railway line follows. So, using some existing infrastructure and reinstating other parts, Oxford’s public transport could be drastically improved. With limited engineering work, new stations could be built on the current track (blue dots on the map below; with more extensive work, the Cowley branch could be reinstated, too (orange dots). Electrify this new six-station route and, hey presto, Oxford has a functioning metro system; the short length of the route also means that few trains would be necessary for a fequent service.

Next up: Leeds. West Yorkshire is a densely populated area with a large number of railway lines. Perfect! I hear you cry. Imperfect! I cry in return. Waaaaaah! Cry the people of Leeds, who, after two cancelled rapid transit schemes, have had enough of imaginative public transport projects.

Here’s a map of West Yorkshire:

Here’s a map of West Yorkshire’s railway network:

The problem is that all of the lines go to major towns, places like Dewsbury, Halifax or Castleford, which need a mainline connection due to their size. Options for a metro service are limited.

But that’s not to say they’re non-existent. For example, the Leeds-Bradford Interchange line passes through densely populated areas; and anyway, Bradford Interchange is a terminus, so it’s poorly suited to service as a through station, as it’s currently being used.

Image: Google.

With several extra stops, this line could be converted to a higher frequency light rail operation. It would then enter an underground section just before Holbeck; trains from Halifax could now reach Leeds via the Dewsbury line. The underground section would pass underneath Leeds station, therefore freeing up capacity at the mainline station, potentially simplifying the track layout as well.

Then you have the lines from Dewsbury and Wakefield, which nearly touch here:

By building a chord, services from Morley northwards could run into Leeds via the Wakefield line, leaving the Dewsbury line north of Morley open for light rail operation, probably with an interchange at the aforementioned station.

The Leeds-Micklefield section of the Leeds-York line could also be put into metro service, by building a chord west of Woodlesford over the River Aire and connecting at Neville Hill Depot (this would involve running services from York and Selby via Castleford instead):

With a section of underground track in Leeds city centre, and an underground line into the north-east of Leeds – an area completely unserved by rail transport at present – the overall map could look like this, with the pink and yellow dots representing different lines:

Et voila! Image: Google.

Leeds would then have a light-rail based public transport system, with potential for expansion using the Karlsruhe model. It wouldn’t even be too expensive, as it mainly uses existing infrastructure. (Okay, the northeastern tunnel would be pricey, but would deliver huge benefits for the area.)

Why aren’t more cities doing this? Local council leaders often talk about introducing “metro-style services” – but they avoid committing to real metro projects because they’re more expensive than piecemeal improvements to the local rail system, and they’re often more complex to deliver (with the lack of space in modern-day city centres, real metro systems need tunnels).

But metro systems can provide huge benefits to cities, with more stops, a joined-up network, and simpler fares. More cities should follow the example of the Tyne and Wear Metro.
