The Internet IS a Series of Tubes: Real-Time Mapping of the London Underground
Shared by reBlog @ Eyebeam
The live train map for the London Underground is a nearly real-time Google Maps mashup that shows the various trains of the London Underground as they move about their subterranean travels.
The train map, created by Matthew Somerville, takes data from the Transport for London API and plots it out on a Google Map. On it, yellow pinpoints represent train stations, and the plethora of slowly moving red pinpoints represent an army of trains. Clicking on a red pin identifies which train you're looking at, the station it just left and where and when it is expected to arrive.
