Matthew Somerville has done a bunch of cool stuff as well as this: http://www.dracos.co.uk/ Just this weekend I stumbled onto his site again when wanting to know where the nearest postbox to my new flat is.

Incidentally there is an official "real time map": http://journeyplanner.tfl.gov.uk/im/RD-T.html It's less cool, but actually tells you at a glance what you really want to know: where disruptions are.

Thanks :-) It would definitely be good if the map could at some point highlight disruptions, or closed stations/lines, yes (along with other things it could show, such as trains at depots if we know where the depots are). Source is available at http://github.com/dracos/underground-live-map :)

Where did you hear of Science Hack Day ?! I've never heard of it and would give a lot to have been there.

Now really annoyed (mutters to self under breath .. muttter mutter mutter ...)

I find the best way to keep track of that kind of thing is following a bunch of well connect geeks on twitter. Frustratingly it clashed with both productcamp and the facebook hackathon.

It would be great to have a london events calender both to keep track of these events and also to avoid clashes.

I didn't know about the hack day, but I found this page through Matthew's twitter:

Reminds me of this. (Though it is much older, and data, as I remember, come only from the timetable, it's not live.) http://www.swisstrains.ch/

There was this one for Helsinki buses for a while: http://transport.wspgroup.fi/hklkartta/defaultEn.aspx

Nice. There's some odd bugs with a couple of the trains... I've just seen one travel from Kings Cross to West Ruislip, off the tracks and in under a minute.

This will be invaluable for any scientist to prove that earth minutes and tube minutes are different.

I really wish this would be available for Amsterdam. I feel like GVB (the organization which organized public transit in the city) wouldn't publish an API.

Half the time I feel like the drivers don't even know where their trams are headed.

It'll be interesting to verify this as the trains pass me by here at home.

i would be interested in verification as well, by looking at it, i think it gets updates frequently, but i'm not sure if they are live or not, but it does seem that based on whichever information it is getting, then it is running a dead-reckoning type interpolation of where the train probably is, and there's nothing wrong with that. however, i would be very impressed at the efficiency of the flow if this was all actual readings all the time.

The interpolation was about 2-3 minutes out and in that time it didn't poll the tfl server as far as I could see. However, when I hit refresh the location was pretty accurate.

Awesome!

I bet Google has the data to add this to there transit maps feature. Is there a way to add locations on a map that use an icon other than the pin?
