Could floating monorails be the transport solution the world’s been searching for?

The story starts, of all places, in Deptford. 

In November 1821, an engineer by the name of Henry Palmer registered a patent for a horse-drawn (yes, really) suspended railway. He built one in 1824, in the dockyards of Deptford to transport goods across factory work sites, and another in 1825 at the brickworks in Cheshunt, Hertfordshire. His second launch was a bit of a coup – passengers rode the line, making it a fairly big deal as the world’s first proper passenger railway only came along a few months later. 

Deutschland, Deutschland, über a river

It was in Germany, however, that the idea really got off the ground (appalling pun intended). Eugen Langen designed a suspended system similar to Palmer’s, which he had intended to sell to the city of Berlin. Instead, it was built in the north-west German town of Wuppertal, in the industry-heavy of the Rhine-Ruhr region that today is Europe’s largest conurbation. A trial run in 1900 saw Kaiser Wilhelm II – yes, that one – take a seat before the line came into operation in 1901, making it the earliest passenger monorail.

The line is still going strong today, and it’s probably the world’s most famous suspended monorail  which, given you’ve probably never heard of it, isn’t saying much. 

It carries around 80,000 passengers a day along its 13km route. Extraordinarily, it dangles over the River Wupper for most of its length, and a full trip would take you about 30 minutes. Although the trains can reach a top speed of 60kmph, they mostly dawdle along at just under 30kmph. There is a certain poetry to it, though – honest. Watch. Just me? OK.

The Germans, at least, seem fond of the system. Between 1973 and 2003, two lines were built in Dortmund and Düsseldorf – both in the same region  and designated the H-Bahn. Dortmund’s line runs predominantly between the north and south campuses of the university, whilst Düsseldorf’s shuttles passengers back and forth between the airport’s various terminals and the long-distance Deutsche Bahn train station.

There’s also a rather bizarre system in Dresden, in the country’s east. It’s about the same age as the Wuppertal system, opened in 1901, and runs 274 metres up a hill between the suburb of Loschwitz and the top of the valley. Somehow it survived the bombardment of the Second World War unscathed, and was repaired extensively in the eighties and nineties, emerging triumphant as something of a minor national treasure.

But the Germans aren’t the only ones.

Ja-planning for the future

There’s the Shonan Monorail in Japan, running almost 7km between two satellite towns of the Tokyo super-blob, and the Chiba Urban Monorail not far away – the world’s longest, at 15.2km. Memphis, Tennessee, is host to a baffling specimen – a 518 metre, 7kmph crawler that runs rather tragically under a footbridge to an amusement park. But the less said about that, the better.

A little closer to the present day, and it’s obviously China that provides the most recent iteration. Chengdu – a whopping, giant megalopolis about the same size as London that we’ve obviously never heard of – is having a go. In September, the city ran a test trial on a 300m stretch of track. The system is, rather radically, powered by lithium batteries – supposedly with a mind to being more cost-effective and environmentally friendly  – and the dangling trains nipped along the single track at a formidable 60kmph. Though the system still has “tens of thousands of kilometres” of test runs to complete before it can open to the public, it’s a promising step.

Shanghai’s also been claiming it will build a transparent suspended monorail to open by 2019, but China’s largest city has always been a dreadful tease, so we’ll save the hype for when we see a real life test.

How to extract NIMBY tears

So that’s the tech – but what can it do? Well. Wuppertal and Chengdu offer hugely valuable lessons for what these systems might be capable of in future – if you’re brave enough.

Wuppertal’s system runs mostly over the river, and we all know how underused most city waterways are these days. Though bridging the Thames every few metres with gargantuan pylons to support an along-the-river line in London would likely prove problematic, there are – contrary to popular belief – other cities in the country.

Cambridge, one of the country’s fastest-growing places, has a beautiful stretch of river running through it.

As it reaches its tendrils southwards with vast housing developments and northwards with a new train station, why not string a suspended monorail over the river? It would never happen, because NIMBYs will out, but it’s a thought. More plausible options include the canals of Birmingham; the River Irwell and Rochdale Canal in Manchester; or the creeping tendrils of Marina Bay in Singapore.

Chengdu’s system, meanwhile, hovers over large roads and highways in a nifty way. Its supporting columns are so narrow that they can be built on the green verge in the middle of the carriageway, at just 80cm in diameter. The list of cities in the world that are low on public transport but high on chokingly enormous highways is a long one indeed.

You can help end this horror by donating just one suspended monorail. Image: Wikimedia Commons,

You could ease congestion on the Hong Kong subway with a line above Connaught Road Central in the city’s heart; give Los Angeles the public-transport boost it craves with lines above each and every freeway; help São Paulo tackle its choking traffic-jam problem with strategically-dangled lines above the metropolis’s crucial thoroughfares.

In short, as we were taught in those devastatingly cringey noughties adverts: the possibilities are endless. Do suspended monorails have all the answers to all the world’s ills? No. Are they an under-considered, undervalued, and under-loved way to top up transport networks without spending billions boring tunnels? Almost certainly.

And that’s good enough for me.

The ATM is 50. Here’s how a hole in the wall changed the world

The olden days. Image Lloyds Banking Group Archives & Museum.

Next time you withdraw money from a hole in the wall, consider singing a rendition of happy birthday. For today, the Automated Teller Machine (or ATM) celebrates its half century.

Fifty years ago, the first cash machine was put to work at the Enfield branch of Barclays Bank in London. Two days later, a Swedish device known as the Bankomat was in operation in Uppsala. And a couple of weeks after that, another one built by Chubb and Smith Industries was inaugurated in London by Westminster Bank (today part of RBS Group).

These events fired the starting gun for today’s self-service banking culture – long before the widespread acceptance of debit and credit cards. The success of the cash machine enabled people to make impromptu purchases, spend more money on weekend and evening leisure, and demand banking services when and where they wanted them. The infrastructure, systems and knowledge they spawned also enabled bankers to offer their customers point of sale terminals, and telephone and internet banking.

There was substantial media attention when these “robot cashiers” were launched. Banks promised their customers that the cash machine would liberate them from the shackles of business hours and banking at a single branch. But customers had to learn how to use – and remember – a PIN, perform a self-service transaction and trust a machine with their money.

People take these things for granted today, but when cash machines first appeared many had never before been in contact with advanced electronics.

And the system was far from perfect. Despite widespread demand, only bank customers considered to have “better credit” were offered the service. The early machines were also clunky, heavy (and dangerous) to move, insecure, unreliable, and seldom conveniently located.

Indeed, unlike today’s machines, the first ATMs could do only one thing: dispense a fixed amount of cash when activated by a paper token or bespoke plastic card issued to customers at retail branches during business hours. Once used, tokens would be stored by the machine so that branch staff could retrieve them and debit the appropriate accounts. The plastic cards, meanwhile, would have to be sent back to the customer by post. Needless to say, it took banks and technology companies years to agree common standards and finally deliver on their promise of 24/7 access to cash.

The globalisation effect

Estimates by RBR London concur with my research, suggesting that by 1970, there were still fewer than 1,500 of the machines around the world, concentrated in Europe, North America and Japan. But there were 40,000 by 1980 and a million by 2000.

A number of factors made this ATM explosion possible. First, sharing locations created more transaction volume at individual ATMs. This gave incentives for small and medium-sized financial institutions to invest in this technology. At one point, for instance, there were some 200 shared ATM networks in the US and 80 shared networks in Japan.

They also became more popular once banks digitised their records, allowing the machines to perform a host of other tasks, such as bank transfers, balance requests and bill payments. Over the last five decades, a huge number of people have made the shift away from the cash economy and into the banking system. Consequently, ATMs became a key way of avoiding congestion at branches.

ATM design began to accommodate people with visual and mobility disabilities, too. And in recent decades, many countries have allowed non-bank companies, known as Independent ATM Deployers (IAD) to operate machines. The IAD were key to populating non-bank locations such as corner shops, petrol stations and casinos.

Indeed, while a large bank in the UK might own 4,000 devices and one in the US as many as 12,000, Cardtronics, the largest IAD, manages a fleet of 230,000 ATMs in 11 countries.


Bank to the future

The ATM has remained a relevant and convenient self-service channel for the last half century – and its history is one of invention and re-invention, evolution rather than revolution.

Self-service banking and ATMs continue to evolve. Instead of PIN authentication, some ATMS now use “tap and go” contactless payment technology using bank cards and mobile phones. Meanwhile, ATMs in Poland and Japan have used biometric recognition, which can identify a customer’s iris, fingerprint or voice, for some time, while banks in other countries are considering them.

So it’s a good time to consider what the history of cash dispensers can teach us. The ATM was not the result of a eureka moment of a single middle-aged man in a bath or garage, but from active collaboration between various groups of bankers and engineers to solve the significant challenges of a changing world. It took two decades for the ATM to mature and gain widespread, worldwide acceptance, but today there are 3.5m ATMs with another 500,000 expected by 2020.

Research I am currently undertaking suggests that ATMs may have reached saturation point in some Western countries. However, research by the ATM Industry Association suggests there is strong demand for them in China, India and the Middle East. In fact, while in the West people tend to use them for three self-service functions (cash withdrawal, balance enquiries, and purchasing mobile phone airtime), Chinese customers consumers regularly use them for as many as 100 different tasks.

Taken for granted?

Interestingly, people in most urban areas around the world tend to interact with the same five ATMs. But they shouldn’t be taken for granted. In many countries in Africa, Asia and South America, they offer services to millions of people otherwise excluded from the banking sector.

In most developed counties, meanwhile, the retail branch and the ATM are the only two channels over which financial institutions have 100 per cent control. This is important when you need to verify the authenticity of your customer. Banks do not control the make and model of their customers’ smart phones, tablets or personal computers, which are vulnerable to hacking and fraud. While ATMs are targeted by thieves, mass cybernetic attacks on them have yet to materialise.

The ConversationI am often asked whether the advent of a cashless, digital economy heralds the end of the ATM. My response is that while the world might do away with cash and call ATMs something else, the revolution of automated self-service banking that began 50 years ago is here to stay.
