This is ingenious coding. What the people over at traintimes.org.uk have done is take live train information from TFL.gov.uk – the people who run London’s underground network, and plot it live on a google map. This was done as part of Science Hack Day and it is SO COOL, though some of my friends aren’t convinced about its usefulness. Personally I’d check this site to avoid long waits on a platform on a day when the trains don’t run as regularly (like a weekend or bank holiday).

Anyway, here’s the link, you can make up your own mind about its usefulness once you’ve picked your jaw off the desk:
