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. Head to Michael's @NetworkNewsUK for more on Liverpool Street station.

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! Support #Railnatter at https://patreon.com/garethdennis.

Back at the start of February, the UK's Transport Select Committee published its report into rail investment pipelines and how to end the boom and bust cycle that double prices and delays improvements... But is the report any good? Does it propose any useful solutions? Will government have any interest in doing anything it suggests? It's a classic page-turn, and you can grab the report yourself, here: https://committees.parliament.uk/work/8739/rail-investment-pipelines-ending-boom-and-bust/publications/ Support #Railnatter at https://patreon.com/garethdennis.

Are there three movies that better define US transit culture better than Speed (1994), Who Framed Roger Rabbit (1988) and The Warriors (1979)? Probably not, if our guest this week is to be believed! Because who could be better to guide us on this silver screen odyssey than Josh Boerman, co-host of @TheWorstOfAllPossibleWorlds and @IllConceived ? Nobody, that's who!

This one's important. If the Greens win, it will end Starmer's short stint as PM and - as importantly - show that Reform are NOT the default winners at the next general election. But can they do it? Transport is a key local issue in this byelection, and given its importance for communities and indeed the future of our democracy, it was time to create a new scoring system to help target where improvements need to be made: the PROCIV system. It's scientific - and it helps us see what improvements Gorton and Denton must see to make people's lives better. Support #Railnatter at https://patreon.com/garethdennis.

I've been teasing this one for ages, but we are finally looking at how HS2 gives Birmingham and the West Midlands a metro system, and what its wider suburban railway network COULD look like...

Have you heard of Lillian "Curly" Lawrence? Get comfy for a story of genius, wit, charm and tragedy - and of a transgender woman who shaped the model railway scene perhaps more than any other individual. We'll also touch on LGBTQIA+ history more broadly, dipping into the Railway Museum's oral archives as well as looking at existing exhibits through a different lens.

On Sunday, two trains collided near Adamuz in Spain in an appalling, extremely unlikely and hugely tragic crash, which so far has claimed the lives of 40 people. Enough detail has been released that we can plot out how the two trains derailed with reasonable confidence - and that's what we'll do, using photos and video from the scene. Rob and Jamie from Podcasting Is Praxis drop in to explore the aftermath of the crash, and how knowing what the derailment looked like doesn't really answer any of the questions over its cause. We also cover a bit of news. Listen to Praxiscast: https://praxiscast.podbean.com/ Support #Railnatter at https://patreon.com/garethdennis. Merch at https://merch.railnatter.uk.

Northern Powerhouse Rail has been announced by government, again, and this time what's being proposed is even more nebulous than last time... If we ignore Network North, that is. We dig into the details to understand what is being promised, what is new (if anything) and what we've been left since the 2020 high point in UK railway aspirations.

On 6 September 2024, a freight train derailed over a bridge in Audenshaw in Greater Manchester. At the end of 2025, the RAIB published their report into the crash, looking in detail at the sequence of failures that let to this event. It lays out a series of mistakes and engineering limitations that force us to look more closely at the way we run our railway and train our engineers.

We've reached the end of 2025! It's been an extremely difficult year across the board, with some points of light dotted around for nourishment, but I wanted to end with some hope.

Merry Christmas! Raise a glass to all the folk out there this holiday season prodding, building and generally messing about with railways in the freezing cold. It's a brief, last minute news filler episode really - and we'll cover a few things including West Yorkshire mass transit delays, two Slovak trains playing chicken on the same track and negging the IEA.

This week I'm delighted to say that we are joined by Poggy Murray Whitham joining us to talk about moving from the technical to the human side of engineering, abuse, threats, hate - and how to overcome them by thinking about psychological safety as rigorously as we think about physical safety. Last time we spoke was in "my" tent at Rail Live, so I've been looking forward to this!

They did it! Or rather, they did... something! The "new" identity of Great British Railways was released yesterday to noises resembling moisture purped through polyester. Alas, it wasn't the wondrous fanfare this ailing government were expecting, but it also isn't a total disaster.

York is broken - traffic is knackered and the city, with its wonderful medieval core and rivers, barely reaches a fraction of its potential as a result.
