Fatal Passenger Train Derailment

Sunday afternoon in Burlington, Canada, a VIA passenger train—think Canada’s version of Amtrak—derailed shortly after switching tracks. The two engineers in the locomotive and their trainee died in the accident, which is still under investigation.

The National Post covered the story and included a few graphics to explain just what happened. Maps pointed out exactly where the train derailed. The graphic below details how a switch works for those unfamiliar with rail transport.

And lastly, a larger graphic attempts to explain what may have happened in lieu of the final accident report from the Canadian Transportation Safety Board.

Replacing the Bay Bridge for the Long Term

Bridges are vital parts of infrastructure networks connecting two separate pieces of territory, but often they can be choke points. Damage to a bridge can result to isolation at worst and at best long, circuitous reroutes that add significant time to travel. In the San Francisco area authorities are building a new bridge to replace the current Bay Bridge. But as everyone knows, buildings and infrastructure in that area can be significantly damaged during earthquakes. And the area is waiting for the ‘Big One’ that shall come some day or another.

So how to build a new bridge for the long-term that will also survive a major earthquake? The New York Times explains it in an interactive piece accompanying an article. The interactive piece includes an animation with voiceover explaining the details of the design, with diagrams illustrating the components placed next to the video player. At the bottom, anchoring the piece (pun intended), is a photo-illustration of the new bridge’s design.

Fresh Water Bulge in the Arctic Ocean

The BBC has an article on a discovery of a growing bulge of fresh water in the Arctic Ocean. The top of the article includes a large set of graphics that explains the story below and links to an animation. The animation depicts the growth of the Arctic ice sheet from the pressure beneath and plots the height of the ice.

How the Costa Concordia Sank

The Costa Concordia sank nearly a week ago, but the questions of exactly how and why she sank will likely linger for much longer.

The BBC has had extensive coverage of the story, including this page that details what is known about how and why the cruise ship sank.

Earth-sized Planets

Kepler 20 System
Kepler 20 System

We have finally discovered two planets outside our solar system that have roughly the same size as Earth. Unfortunately, unless we learn that life can exist in the form of fire beings, these two planets are too close to their sun to support life. Their temperatures are in the hundreds and thousands of degrees. A bit balmy.

The New York Times has a small but interesting chart that fits inline with its article, at least on its website—presumably it fits similarly in its printed form. Seen here to the left, it plots the orbital distance of the planets that are known to orbit the star Kepler 20. (Unfortunately these planets have less than creative names: Kepler 20e and Kepler 20f.) The other planets are gas giants.

The use of scale of orbits and the gap between 20f and 20d allow for an annotation within the image. And then with a little bit more vertical space, to drive hom the point of these new planets’ nearness to their sun, the orbit of Mercury, the planet nearest our sun, is plotted for comparison.

The Family Tree of Kim Jong Il

Kim Jong Il is dead. And nobody really knows what is going to happen in North Korea.

But, what we do have, is the interactive family tree of Kim Jong Il, courtesy of the BBC. Select individuals are clickable and have short biographical sketches. Unfortunately, the tree has been simplified for clarity and it does not contain all members of the family.

Exporting the Sun

Plans are afoot to harness the power of the sun in the deserts across northern Africa. The electricity generated in Morocco is planned to turn on light switches in Madrid and throughout the rest of Europe.

The Guardian created a map to show how the solar facilities could be connected to each other and to other renewable power sources in Europe—from Icelandic geothermal plants to North Sea wind turbines to Alpine hydroelectric plants.

We Want to (Quell a) Riot (with Military Grade Hardware)

The New York Times had a piece in the Sunday paper asking whether American police have gone military, especially in the wake of the images of the police response to Occupy Oakland and Occupy Wall Street with police/troops deployed in tactical body armour, armoured vehicles, &c. The Times piece was accompanied by an Op-Art piece that took three key protests and illustrated the type of police officer responding to the unrest.

China’s Secret Nuclear Missile Tunnel System

I do not often get the chance to post illustrative works. But, the Washington Post reported on the work of Georgetown students that shows how China has tunneled thousands of miles of, well, tunnels to create a secret labyrinth for their nuclear weapons programme. The result is that instead of the few dozen warheads that China is thought to have, they could have many more times that. They included this graphic, cropping below, with the article.

The New York City Marathon

Something I’ve been meaning to put up for a little while, the New York Times’ coverage of that city’s marathon and changes in the socioeconomic composition of the neighbourhoods through which the course winds.

The piece includes a narrated motion graphic explaining the changes along a map of the course, while a series of charts look at those factors from a static perspective. The horizontal axis being the route of the course.
