Is Sadiq Khan cancelling the Garden Bridge by stealth?

Could this be it? Could it finally be happening? Could the biggest debate in Greater London politics – “Should we spend a small fortune building a bridge next to an existing bridge?” – really be about to come to its conclusion?

Anything’s possible. From this week’s Architect’s Journal:

London’s new mayor has effectively suspended work on the Garden Bridge because of concerns that an enabling project at Temple Tube station will lead to more public money being spent on the £175m project.

Transport for London’s (TfL) finance and policy committee had on Friday (8 July) been due to rubber-stamp £3m of London Underground spending on strengthening the station’s structure to withstand the weight of the Thomas Heatherwick-designed bridge on its roof.

But Sadiq Khan has now ordered the work – by engineer Flint & Neil, and approved by his predecessor Boris Johnson two months before May’s mayoral election – to be halted because of his commitment not to spend any more taxpayers’ money on the bridge.

At first glance this seems a bit odd because, a mere six weeks ago, Khan was arguing that the Garden Bridge should absolutely, definitely go ahead.

His argument was that so much had been spent on it already (taxpayer contribution to date: £37.7m) that it would effectively now cost more to cancel it than it would if we finished it, thus enabling it to start making money and repaying some of its loans (final projected taxpayer contribution: £18m).

So has he u-turned? Well, it’s possible. He already has form, and a certain flexibility on matters of policy increasingly looks like Khan’s defining ideology.

But of course, he hasn’t actually scrapped the Bridge at all – he’s doing something altogether more subtle. Here’s a mayoral spokesman quoted in that AJ article:

Sadiq Khan has been clear that no new public funds should be committed to the Garden Bridge, and he has pledged to make the project more open and transparent – standards that were not always met under the previous administration.

So, no, Khan hasn’t scrapped the Bridge – he’s just requiring it to live within its means. After all, the Garden Bridge Trust has told us repeatedly that there’s a robust financial case for the Bridge: so getting it built without dipping into the public purse yet again should be easy, right?


In other words: either the Garden Bridge happens, without Sadiq Khan committing another penny, and he’ll be able to take the credit (just as Boris Johnson took the credit for Ken Livingstone’s cycle hire scheme); or the Garden Bridge doesn’t happen, and it’ll be because the previous administration mucked up the finances.

Either way, Khan wins, and he doesn’t have to be the mean-spirited mayor who cancelled something beautiful.

He’ll go far, that boy.

Incidentally – wondering why a new Bridge would require us to spend £3m on rebuilding a tube station? Because the northern end of it will look like this:

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.
