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.

In the first of a series of chats with political leaders who are shaping the mobility landscape in the UK, I was delighted to spend a long lunch with Maryam Eslamdoust, general secretary of the TSSA. We talked about a range of subjects including union saturation into the consultancy world, the Iran war and its impacts on the cost of living, rail reform and GBR, as well as her current campaign on violence against transport workers.

Join our chat in the TSSA office and on a multi-train adventure in East London - with extra bits to follow in the bonus.

10 hours, 22 locations and about 100 miles (probably) of travel later, and we've got a real feast of an episode to mark our 300th... Tonight, we rate ALL OF LEEDS for mobility using our patented science-based system: the PROCIV system. In doing so, we will consider the West Yorkshire mass transit plans and whether they are prioritising the right solutions.

We'll also drop a few bombshells, not least a reminder how much was spent on a pointless new bypass for part of Leeds in 2025!
