Anyone know how accurate the live train maps are? Also, off topic, but the bus maps seem a bit off as the bus locations are sometimes no-where near the line of route. For example, the RV1 is shown as up by bethnal green!

The National Rail one fetches data from the National Rail live departure boards and then interpolates/extrapolates based on that. The data refreshes every half hour or so, and carries on based upon the fetched information, so won't e.g. get immediate changes. So not totally accurate by any means, but hopefully not wildly inaccurate either :) The Underground version fetches its data every two minutes, and its source code is available at https://github.com/dracos/underground-live-map

The RV1 looked okay a bit earlier, but it's quite possible there's something wrong somewhere. The same repo as above has the London buses code in it too (in data/bus.php), all the information comes from TfL's API so issues could be with their source data. In general, it seems to run okay :)
