Friday Lunchtime Lectures at the Open Data Institute. For our fourth lecture... How can open data revolutionise your rail travel?

The release of open data on public transport over the last year has laid bare the the secrets of cheap fares, true timekeeping records and the best alternative routes the official journey planners don't tell you.

Jonathan Raper, digital geographer and founder of Placr, will draw back the curtain on this new era and reveal how you can make the most of it.
