#RailNatter Episode 187: HS2 has been cancelled, so what happens next? (a Q&A) 11.10.2023

Well, as predicted by me in 2018, and then essentially confirmed as inevitable two years ago on release of the Integrated Rail Plan, this Conservative government of Hunt, Sunak and Harper have cancelled HS2, leaving the most expensive section between London and Birmingham as a rump to be picked at by Treasury vampires until it is impossible to deliver the full scheme. There's so much to talk about...

#RailNatter Episode 186: Putting geofencing to good use to improve track safety 04.10.2023

We are joined by the founder and CEO of Tended, Leo Scott Smith, to talk about how you turn an idea into a solution that can save lives... And we'll talk a bit about how the railway forms the perfect filter to sort pointless from purposeful tech. Geofencing is used pretty widely these days, but protecting staff on track is a particularly tricky and critical application - and this is where Tended c...

#RailNatter Episode 185: Why the UK aviation industry is in steep decline 27.09.2023

In what might prove to be another cornerstone episode of #RailNatter, Dr Alex Chapman from  @theneweconomics  discusses his research into the economic benefits of the aviation industry to the UK... Or rather the fact that there aren't any. Seriously - this is fascinating stuff and lays bare the ideology behind the disproportionate subsidy of the airline industry in the UK and further afield... All...

#RailNatter Episode 184: A Wander Around Wonderlab (the NRM’s new gallery) 22.09.2023

Join @MrTimDunn and me as we dash around the @NatRailwayMuseum 's new gallery - Wonderlab - in the only way we both know how... Chaotically! We have the most tremendous fun whizzing around what I think is likely to be my second favourite space in the NRM after the warehouse/North Shed, BECAUSE THIS SPACE IS SO GOOD (particularly for me as an infrastructure person)! Want to know what it is all abou...

#RailNatter Episode 183: The Belgrade-Bar railway, Kolašin to Bar 13.09.2023

It's the finale of our three-part odyssey through the former Yugoslavia, following one of the world's most scenic railways from Belgrade in present-day Serbia to Bar in present-day Montenegro. We've reached the highest point of the line, and only have a limited length of line to get back down to sea level... And there are a few feats of spectacular engineering required to get us there! Enjoyed thi...

#RailNatter Episode 182: Electric vehicle chargers should be kept off pavements 06.09.2023

Leo Murray has finally joined us to talk about the latest invasion of car infrastructure onto our pavements - that's right, electric vehicle charging points are the latest menace we are having to negotiate. But given we do actually need these things to be installed, how do we go about it? What's the scale of the problem? And what does "good" look like? Enjoyed this? Please do consider supporting #...

#RailNatter Episode 181: The Belgrade-Bar railway, Užice to Kolašin 30.08.2023

It's the second of a three-part odyssey through the former Yugoslavia, following one of the world's most scenic railways from Belgrade in present-day Serbia to Bar in present-day Montenegro. We're truly nestled in the heart of the mountains in western Serbia at this point, and indeed we take a wee trip into Bosnia before eventually ending up in Montenegro... This time we journey from Užice to Kola...

#RailNatter Episode 180: Ban Private Jets, Make The World Better 23.08.2023

I'm very pleased this week to have been joined by Hannah Lawrence from Stay Grounded, talking about the legitimacy of flying, the inequality of flying, and campaigning against the worst excesses of aviation.

#RailNatter Episode 179: The Belgrade-Bar railway, Belgrade to Užice 16.08.2023

It's the first of a three-part odyssey through the former Yugoslavia, following one of the world's most scenic railways from Belgrade in present-day Serbia to Bar in present-day Montenegro. This is the first three hours of the trip, distilled down by an enormous factor into a... one hour episode. We get from Belgrade to Užice. Enjoyed this?

#RailNatter Episode 178: How do you build a modern train simulator game? 09.08.2023

This week, we're joined by two of the Dovetail Games team to talk all things train simulation... Matt Peddlesden (executive producer) and Joseph Rogers (brand manager for Train Sim World, WSR volunteer) will take us on an odyssey of discovery on how you research, develop and expand train simulation games! Join me and the Dovetail Games crew LIVE on Wednesday at 7pm to ask your questions! Enjoyed t...

#RailNatter Episode 177: Are any of the ”new” HS2 eastern leg options good? 02.08.2023

HS2 has, once again, been in the news, now that the Infrastructure Projects Authority (not beer related) has said the project may be unachievable, which won't be news to viewers of course. Anyway, government has responded to the Transport Select Committee's IRP report, and several Yorkshire councils have published their proposals for getting HS2 trains up to Leeds and the North East. Basically, a...

#RailNatter Episode 176: A Week In The Life Of A Railway Managing Director 26.07.2023

This week #RailNatter is joined by the managing director of ScotRail - or rather, of Scotland's Railway, the alliance of organisations that run rail services in Scotland. That's right - Alex Hynes is joining us to talk about the direction that Scotland's railways are going in, balancing the needs of policymakers and operations, and what exactly the current structure of Scottish railway operations...

#RailNatter Episode 175: Dave Grohl Takes The Train (and other news stories) 19.07.2023

It's a news episode, and there's so much to catch up on... more HS2 mess, bad on-demand buses, the continuing demise of Translohr, the dreadful Odisha train crash in India, diminishing pay across the GB rail industry, and so much more. Join LIVE on Wednesday at 7pm. Enjoyed this? Please do consider supporting #RailNatter at https://patreon.com/garethdennis or throw loose change at me via https://p...

#RailNatter Episode 174: How to make railway fandom a bit more inclusive 12.07.2023

We've the delight this week of being joined by Emily Turner of  @roundelroundwego  to talk about railway and transport fandom, what it is, how some of its tropes can be off-putting, and how making it more inclusive is a bonus for everyone involved... Including industry itself. Enjoyed this? Please do consider supporting #RailNatter at https://patreon.com/garethdennis or throw loose change at me vi...

#RailNatter Episode 173: The Great British Ticket Office Closure 05.07.2023

#RailNatter Episode 171: It’s The 120th Birthday Of The Windscreen Wiper 21.06.2023

It's a fun one, and some engineering history for you all... 120 years ago, give or take a few days, the patent was placed for what would become the modern windscreen wiper, a vital safety device that we all take for granted. But how many of them can I find in the  @NatRailwayMuseum  ? Why do we know of so few women inventors? Why do I always end up in the Warehouse? All questions I'll attempt to t...

#RailNatter Episode 170: What went wrong at the National College for High Speed Rail? 14.06.2023

In sad news, a vital facility for plugging the UK rail skills gap has been abandoned to rot... But why? We'll talk about how the college came about, its poor management from the off, the non-existent strategic planning that led to its demise, and will remind ourselves of what we've lost.

#RailNatter Episode 167: Why do crossing noses crack? 24.05.2023

Our very special pilgrimage site of Colton Junction suffered a catastrophic (but all too common) failure this week, and so it seems like a good chance to talk about crossing noses, what they are, why they fail and how we can stop them failing. May or may not include gratuitous imagery of Colton Junction's fabulous equal splits. Enjoyed this? Please do consider supporting #RailNatter at https://pat...

#RailNatter Episode 166: Two half-forgotten but important railway crashes from the 1980s 17.05.2023

This week we are looking at two rail crashes, one at Pitlochry in Scotland and another at Pershore in Worcestershire, that took place in the 1980s. Thankfully, neither involved serious injuries, but both incidents can teach us a few things, despite having been mostly forgotten... Including the unforeseen side-effects of introducing new bits into dynamic engineering systems like railways. Enjoyed t...

#RailNatter Episode 165: What really happened when the Tesco tunnel collapsed? 10.05.2023

This week's #RailNatter is a return to Gerrards Cross and all the shenanigans that led a tunnel with a Tesco on it to collapse onto a live railway... Why did the HSE not publish their original report? Well, thanks to an intrepid fan of the show, we've finally got hold of it! We'll be lawyering up as we flick through the pages of the draft report and stare in horror and the engineering negligence t...

#RailNatter Episode 164: Should you go fast or slow over a collapsed rail bridge? 03.05.2023

It's an age-old question... A rail bridge is out, only the rails are left, so do you take the train fast or slow over the bridge? There's a lot to think about: gravity, dynamics, waves, stiffness, materials, energy, vibrations... All combine to give us the answer. But what is it? It's slow - you obviously drive slowly over the dang bridge! Anyway, hopefully this will explain why! Enjoyed this? Ple...

#RailNatter Episode 163: Just how much more public transport does the UK need? 26.04.2023

Last week, the TUC published their report "Public transport fit for the climate emergency" and, in classic #RailNatter style, we are going to sift through it page by page! Having only really flicked through it up to this point, this report appears to dig deeper into my "rail capacity needs to double by 2050" figure and comes out showing this looks to actually be an underestimate. Union researchers...
