The train company, the government, even the military are at a loss: no-one can figure out what is causing the problem. Until Jason Bay and his team of data scientists assemble an old-fashioned timetabling graph, first developed in 19th century France, which exposes an invisible culprit.Behind every line on a graph, there lies an extraordinary human story.

Hannah Fry tells a tale of data detectives and very naughty trains.Presenter: Hannah FryExecutive Producer: Martin SmithSeries Producer: Lauren Armstrong-CarterEpisode Producer: Ilan GoodmanA series for Radio 4 by BBC Science in Cardiff.
