Needed station data for building http://housequest.co.uk (sorry, cheeky plug) and there wasn't one up to date source out there so I reckoned I'd share this. Used a bunch of sources such as wikipedia, http://www.doogal.co.uk/london_stations.php which needed some updating.
In the repo you'll also find the .csv file for stations and a GeoJson of the London Boroughs aligned to Google Maps based on https://www.google.com/fusiontables/DataSource?docid=1WlXk5R...
