  • Entertaining and Informative

    Bye heck Richard I’m agog. I don’t know how many Pendalino launches there was but this pod cost covers all of them - and so much more. The hosts are entertaining and very easy to listen to. Complex issues are broken down so that anyone can understand. They often manage to get an interview with the leaders or politicians at the heart of the issue. I’ve been catching up on earlier episodes and have throughly enjoyed learning more how the railways are organised and run

  • Railways and Right Wing Politics

    Good for UK Rail News but increasingly it drips Right and Far Right politics. Every UK Government member is it seems a fool or untrustworthy. Presumably the withering sarcastic tone will end if either Farage or Lowe gets to run the railways

    Great podcast mixing business and a bit of gricing (more of the former for me please). But it’s so so quiet and almost impossible to hear when walking through London. Please adjust the volume

Talking Points

Recent interactions between the hosts and their guests.

154. TransPennine Express’s new train order is great news! But we have questions…
Q: What does the ORR-regulatory reform imply for open access and freight operators as rail reform progresses?
The ORR decision-maker shift toward advisory roles aims to keep focus on outcomes, with an emphasis on ensuring fairness in access, monitoring, and enforcing licenses while allowing space for industry input; a formal industry scorecard was suggested to align government bodies and operators on shared outcomes.
£1bn NEW trains! Britain's first mainline battery electric trains ordered by TransPennine Express
Q: What does this order mean for customers in the North of England?
It signals faster, more reliable services with better accessibility, including level boarding, and a more flexible fleet that can operate with or without overhead power, improving timetables and resilience.
144. Failure to electrify Britain’s railway is costing the UK £Billions!
Q: What is the recommended approach to electrification in the UK?
Adopt a rolling program that prioritizes trunk routes with clear business cases for full electrification, while also implementing discontinuous electrification and battery options on routes where the economics are compelling, to maintain progress and workforce continuity.
144. Failure to electrify Britain’s railway is costing the UK £Billions!
Q: Why now, and why India as a comparison for electrification?
India's electrification pace demonstrates how a large, growing network can be electrified rapidly when there is political will and a strong railway ministry, offering lessons on scaling and deployment that the UK could adapt through a rolling electrification program.
141. Is the Government’s Rail Reform failing? And how do we fix it?
Q: Is rail reform really working or is it failing?
The hosts suggest that while some changes are visible (like newly released arterial trains), there are still deep structural issues and cost pressures that may undermine the promised benefits, making the reform feel more iterative than transformative.
