Here’s a live map of every train on the UK national rail network to play with

It’s that time of the day again. You’re a bit sleepy after lunch, your motivation has completely collapsed, and you know, in your heart of hearts that you're not getting anything else done today.

But it’s still not quite late enough to start very slowly packing up your stuff or smiling round at your colleagues and optimistically muttering, “Pub?” Basically, you’ve just marking time.

So, here’s a map showing the location of almost every train on Britain’s National Rail network, that should help kill a few hours.

The busy south London rail network.

It’s the work of Raildar (geddit?) which describes itself as “a leading website providing up to date Train information”. If you pay for subscription you can get access to all sorts of exciting things like station dwell times and detailed performance data. You also get a year’s historic performance data which means, I think, that you can check whether the 0903hrs from London Euston to Manchester Piccadilly ran on time on a particular day last June.

But if you’re a strictly amateur nerd, there’s lots of free stuff to play with too, including track layout and junction maps...

This is the Euston/King’s Cross area. Click to expand.

On the dynamic version on Raildar's website, you can literally see trains moving around the network.

I find such technical maps pretty hard to read, though (odd, given my obsession with tube maps). So I went straight to the geographically accurate Rail Radar section, which is literally just Google Maps with live train movements superimposed on top. The trains are coloured by operating company; and you can click on them to find out where they’re going and how late they’re running. That includes both local trains:

And long distance ones:

This train just outside Edinburgh is going all the way to Plymouth:

Which is going to take a while:

In some ways, the most fun – for a certain value of fun – is to be found by comparing the big cities. London is pretty crowded with trains:

(This isn’t even all of them – it doesn’t include any of the TfL-run services.)

Here’s the north west at the same scale:

 

Okay, that area has about half London’s population, but that looks like a lot less than half of London’s trains. Although these chaps might have a point:

West Yorkshire looks much the same:

 

And the West of England is practically deserted:

Perhaps the data is incomplete, but at the time I took this screenshot, the map wan’t showing a single train anywhere in the county of Cornwall.

The map is definitely not comprehensive. It doesn’t show routes run by Transport for London – not just the tube, but not TfL Rail, either. (The Overground seems to be on there.)

This sort of makes sense at first glance – this is National Rail, after all – but it does show trains on Merseyrail, so who knows. I was going to write that it shows the Tyne & Wear Metro, too, but on closer inspection I can only find one train, and I’m fairly sure the Tyne & Wear metro has more than one train running right now..

More vexingly, the Anglia Rail lines to Southend seem to be missing, too. There may well be others missing from parts of the country I’m less familiar with, too.

Anyway – even if it isn’t perfect it is a lot of fun, assuming you’re a train nerd, which I’m guessing you probably are. And you can do useful things with it like check how late your train is running, too, if that’s your bag.


It’s good. You should play with it, is what I’m saying here.

The IPPC report on the melting ice caps makes for terrifying reading

Earlier this year, the Intergovernmental Panel on Climate Change (IPCC) – the UN body responsible for communicating the science of climate breakdown – released its long-awaited Special Report on the Ocean and Cryosphere in a Changing Climate.

Based on almost 7,000 peer-reviewed research articles, the report is a cutting-edge crash course in how human-caused climate breakdown is changing our ice and oceans and what it means for humanity and the living planet. In a nutshell, the news isn’t good.

Cryosphere in decline

Most of us rarely come into contact with the cryosphere, but it is a critical part of our climate system. The term refers to the frozen parts of our planet – the great ice sheets of Greenland and Antarctica, the icebergs that break off and drift in the oceans, the glaciers on our high mountain ranges, our winter snow, the ice on lakes and the polar oceans, and the frozen ground in much of the Arctic landscape called permafrost.

The cryosphere is shrinking. Snow cover is reducing, glaciers and ice sheets are melting and permafrost is thawing. We’ve known this for most of my 25-year career, but the report highlights that melting is accelerating, with potentially disastrous consequences for humanity and marine and high mountain ecosystems.

At the moment, we’re on track to lose more than half of all the permafrost by the end of the century. Thousands of roads and buildings sit on this frozen soil – and their foundations are slowly transitioning to mud. Permafrost also stores almost twice the amount of carbon as is present in the atmosphere. While increased plant growth may be able to offset some of the release of carbon from newly thawed soils, much will be released to the atmosphere, significantly accelerating the pace of global heating.

Sea ice is declining rapidly, and an ice-free Arctic ocean will become a regular summer occurrence as things stand. Indigenous peoples who live in the Arctic are already having to change how they hunt and travel, and some coastal communities are already planning for relocation. Populations of seals, walruses, polar bears, whales and other mammals and sea birds who depend on the ice may crash if sea ice is regularly absent. And as water in its bright-white solid form is much more effective at reflecting heat from the sun, its rapid loss is also accelerating global heating.

Glaciers are also melting. If emissions continue on their current trajectory, smaller glaciers will shrink by more than 80 per cent by the end of the century. This retreat will place increasing strain on the hundreds of millions of people globally who rely on glaciers for water, agriculture, and power. Dangerous landslides, avalanches, rockfalls and floods will become increasingly normal in mountain areas.


Rising oceans, rising problems

All this melting ice means that sea levels are rising. While seas rose globally by around 15cm during the 20th century, they’re now rising more than twice as fast –- and this rate is accelerating.

Thanks to research from myself and others, we now better understand how Antarctica and Greenland’s ice sheets interact with the oceans. As a result, the latest report has upgraded its long-term estimates for how much sea level is expected to rise. Uncertainties still remain, but we’re headed for a rise of between 60 and 110cm by 2100.

Of course, sea level isn’t static. Intense rainfall and cyclones – themselves exacerbated by climate breakdown – can cause water to surge metres above the normal level. The IPCC’s report is very clear: these extreme storm surges we used to expect once per century will now be expected every year by mid-century. In addition to rapidly curbing emissions, we must invest millions to protect at-risk coastal and low-lying areas from flooding and loss of life.

Ocean ecosystems

Up to now, the ocean has taken up more than 90 per cent of the excess heat in the global climate system. Warming to date has already reduced the mixing between water layers and, as a consequence, has reduced the supply of oxygen and nutrients for marine life. By 2100 the ocean will take up five to seven times more heat than it has done in the past 50 years if we don’t change our emissions trajectory. Marine heatwaves are also projected to be more intense, last longer and occur 50 times more often. To top it off, the ocean is becoming more acidic as it continues to absorb a proportion of the carbon dioxide we emit.

Collectively, these pressures place marine life across the globe under unprecedented threat. Some species may move to new waters, but others less able to adapt will decline or even die out. This could cause major problems for communities that depend on local seafood. As it stands, coral reefs – beautiful ecosystems that support thousands of species – will be nearly totally wiped out by the end of the century.

Between the lines

While the document makes some striking statements, it is actually relatively conservative with its conclusions – perhaps because it had to be approved by the 195 nations that ratify the IPCC’s reports. Right now, I would expect that sea level rise and ice melt will occur faster than the report predicts. Ten years ago, I might have said the opposite. But the latest science is painting an increasingly grave picture for the future of our oceans and cryosphere – particularly if we carry on with “business as usual”.

The difference between 1.5°C and 2°C of heating is especially important for the icy poles, which warm much faster than the global average. At 1.5°C of warming, the probability of an ice-free September in the Arctic ocean is one in 100. But at 2°C, we’d expect to see this happening about one-third of the time. Rising sea levels, ocean warming and acidification, melting glaciers, and permafrost also will also happen faster – and with it, the risks to humanity and the living planet increase. It’s up to us and the leaders we choose to stem the rising tide of climate and ecological breakdown.
