#RailNatter Episode 37: Why is it so important to tell people that Hyperloop is bad? 26.11.2020 1:11:49
There’s been a lot of transport nonsense in the news recently: Hyperloop pretended it carried some passengers, Elon Musk’s Loop outed itself as completely useless, the Cambridgeshire Autonomous Metro is asking for people to submit ideas as to what on earth it is… In all cases, real transport solutions are pushed further away. So I thought I’d do an episode of #RailNatter explaining why it is so im...
#RailNatter Episode 36: What exactly is sustainability? (with Simon Kendler) 25.11.2020 1:48:34
In Episode 36 of #RailNatter , we are being joined by bona fide young rail professional Simon Kendler! Given that both of us call ourselves sustainable transport advocates, we thought it would make sense to discuss what exactly “sustainability” means in a transport context… What constitutes “sustainable” transport? Is it all about the colour green? Are railways sustainable? Is anything? Join us LI...
#RailNatter Episode 35: Scenic Rail Tours Of An Hour In Length – Inverurie to Elgin 18.11.2020 1:17:29
For Episode 35 of #RailNatter , we are trying a new intermittent format: Scenic Rail Tours of An Hour In Length (as requested by the Patreon people)! For the first episode, we are going back to my roots and taking a virtual trip from Inverurie to Elgin… What is there to see and do? What will we find out along the way? Will this format actually work? Join LIVE to find out! Here’s the link to the NL...
#RailNatter Episode 34: A Correspondent’s Guide to Europe’s railways 11.11.2020 1:40:03
This week, I am very pleased to say we have long-time audio-only #RailNatter listener (oh, and the Independent’s Policy Correspondent) Jon Stone joining us to talk about his experiences of mainland Europe’s railways during his time posted as Brussels correspondent… Where could Britain learn from our mainland railway colleagues? Is there anything that we do better? Just how terrible is #RailNatter...
#RailNatter Episode 33: Would a fixed link to Northern Ireland work? 29.10.2020 1:13:24
In Episode 33 of #RailNatter , we are looking at what a fixed link to the island of Ireland (via Northern Ireland) might look like… Should it be high speed? Are either a bridge or a tunnel possible? Should it link from Wales, England or Scotland? How much might it cost? Given that Boris Johnson likes the idea, is the whole thing completely nonsensical from an engineering perspective? Join me LIVE...
#RailNatter Episode 32: The Island of Tube Trains 23.10.2020 59:55
This week (or rather, a month ago as this is a pre-record), railway writer Richard Long is joining us to talk about the mysterious Island of Tube Trains, or the Isle of Wight as it is generally written on the map. This will be a #RailNatter full of tales of little engines, gauge clearance and a second chance for many a former metro train… Buy Richard’s book here: https://www.amazon.co.uk/-/e/B01DS...
#RailNatter Episode 31: Is level boarding on trains really that hard to achieve? 23.10.2020 1:30:55
This week’s #RailNatter aims to get to the root of an issue incredibly close to my heart, and something we as an industry do a very bad job of: actually letting everyone get on our trains. In Episode 31, we’ll be looking at the issue of level boarding: what do I mean by this, why is it an issue, and is it as hard to achieve as lots of people say it is? I’ll also look at why an industry in the 2020...

#RailNatter Episode 29: A hundred* ways for railway rails to fail 30.09.2020 1:40:44
In this week's #RailNatter , I'm talking about all of the ways in which railway rails - yes, just the rails themselves - give up and stop holding trains up in the air. What's a squat? Fatigue got you down? Want to crack gauge corner cracking? Well, this is the episode for you... Join LIVE to ask your questions and I'll do my best to respond! *we won't be covering one hundred failure modes Enjoyed...
#RailNatter Episode 28: Quails on Rails (with Dr David Turner) 23.09.2020 1:32:19
The venerable Dr David Turner is back on the show! In Episode 28 of #RailNatter , we'll be turning our attention to the humble quail... Why? Well, because it allows us to explore the shape and development of supply chains on the British railway network through time, including thinking about how they operate now. It also lets us look at wider international supply chains, and how for a long time fre...
#RailNatter Episode 27: The Traction Decarbonisation Network Strategy (phew) 16.09.2020 2:02:59
In a change to the announced schedule, Episode 27 of #RailNatter is going to be a marathon page turn of Network Rail's freshly published Traction Decarbonisation Network Strategy - a.k.a. The Electrification Map Report! Join us LIVE as we flick through all 257 pages, check out all of the areas that AREN'T proposed for wiring and consider how realistic it is that Britain might finally get the rolli...

Well here we go - it is finally time for a #RailNatter with interactive railway creation... In Episode 25, I'll be providing you with the tools you need to make your crayon railways as realistic as possible! I'll show you how to dodge towns, make use of existing alignments and skip your way between ancient woodlands as we look over a few examples of railways that I've already fiddled with... Join...
#RailNatter Episode 24: Is road pricing the future? (with Edward Leigh) 26.08.2020 1:29:49
We've talked about it before, but what is road pricing and is it the future for managing road traffic? Well, this is what Edward Leigh (leader of Smarter Cambridge Transport) and I will be talking about in Episode 24 of #RailNatter ! With electric vehicles being the future of road transport, income from fuel duty will start rapidly decreasing. At the same time, road users need to be rewarded for r...
#RailNatter Episode 23: The Tube Mapper Project (with Luke Agbaimoni) 19.08.2020 47:58

#RailNatter Episode 22: Making Electrification Stick (with Garry Keenor) 12.08.2020 1:30:35
In this week's #RailNatter I'm very pleased to say we will be joined by the electrifying Garry Keenor (@25kV on Twitter)! In Episode 22, we'll be talking about all things OLE (OCS if you're elsewhere in the world)... Given that national electrification was suggested seriously back in the 1910s, how on earth can we finally get Britain to #ElectrifyAllTheThings , over a century later? Join us LIVE t...
#RailNatter Episode 21: Light Rail Is Not A Metro (and other gripes) 05.08.2020 1:17:14
Episode 21 of #RailNatter is being hijacked as a #NotAMetro soapbox! This is one of my all-time bug-bears: what is and is not a “metro”, and why the UK in particular is fixated on calling tram systems “metros” despite them being a long way short of that. But where does the line sit? Is the DLR a metro? Is the Tyne and Wear Metro a metro? Is Thameslink a metro? Watch to see as I try to create the d...
#RailNatter Episode 20: So Just What Structure Should Britain‘s Railways Have Anyway? 29.07.2020 1:23:59
Episode 20 of #RailNatter is going to be an hour of me making a rod for my own back, no doubt... Why? Because I am going to make my proposal for what the organisational structure of Britain's railways should look like! Do I want a return to Grouping? Sectorised BR? The Japanese model? Tune in to find out! (Here's Alasdair Rae's CityMetric piece explaining his Federal England map: https://www.citym...
#RailNatter Episode 19: STEM or STEAM (with Lucy Prior MBE) 22.07.2020 1:00:29
We're LIVE again for Episode 19 of #RailNatter , and I am very pleased to say we'll have the brilliant Lucy Prior MBE joining us to talk about STEM... or is that STEAM? Science, Technology, Engineering, ARTS and Mathematics: Are we broadening the description too much, or are we just acknowledging that engineering is as creative as it is technical? This is the subject that got the two of us togethe...
#RailNatter Episode 18: Morpeth Curve 15.07.2020 1:00:25
Morpeth Curve - a ridiculous kink in Britain's 125mph East Coast Main Line that has tipped more than one train into the adjacent housing estate... In this week's #RailNatter , I'll be postulating on why it exists, looking at what we might do about it, and thinking on the tragedy and comedy of successive derailments in this small Northumbrian town. I'm away for this one... But through the wonders o...
#RailNatter Episode 17: The Woodhead Route 08.07.2020 1:12:15
Seeing as trans-Pennine infrastructure was in the news recently, this week's #RailNatter is going to cover THE WOODHEAD ROUTE and why "reopening" it is an idea beloved by nostalgists that isn't rooted in reality. Join me to tell me why I'm wrong - and it's just me this week, so we'll be doing a lot of nattering, no doubt! Enjoyed this? Please do consider supporting #RailNatter at patreon.com/garet...

In this week's #RailNatter , Andrew White is joining us to talk about a topic close to our hearts, but perhaps from an unusual angle... What are the BENEFITS of closing railway lines? Are there any? Are we doing the work of the devil in even talking about closing railways? Join us LIVE to get involved and tell us what you think! Check out Walks Around Britain at their website: walksaroundbritain.c...
#RailNatter Episode 15: Art on the Underground (with Charlotte Monroe) 24.06.2020 1:53:19

#RailNatter Episode 14: Building railways, but with less carbon... 17.06.2020 1:16:24
This week, I'm delighted to welcome Prab onto #RailNatter ! In Episode 14, we'll be talking about carbon emissions in construction... How do you calculate them? How do you reduce them? Are we doing enough? Is concrete evil? We'll also touch on the experiences of entering and thriving in the rail industry as someone who doesn't fit within the "prevailing engineering demographic". Circular Ecology W...
