This train TRANSFORMED Britain’s railways | #Railnatter 302

This week we are talking about Network Rail's PLPR train - the incredible and now pretty experienced train that put machine learning into practice in a way that makes today's AI boosters look more like hucksters than they already are. Alex Cusdin joins us to talk through the train and its tech, and tell the story of how it came into being. Capturing an incredible 18TB of data a day, this train captures 70,000 photos a second to enable a very high resolution view of the track to automate and improve inspection, in the process making railways safer. This is an example, now well proven, of how technologies can be applied to make better use of skilled people, rather than displacing them. And it's about to be replaced.
