This is my heaven.
Let the train take the strain... With bonus heritage traction thrown in for good measure.
Key question: will the yaw dampers fall off and bop me on the nose? Secondary question: will it burst into flames unprompted?
Here's a view inside an empty freight train:
Here's a view of the top of another freight train:
Here's a twin-track cantilever, a single track cantilever and copious volumes of new, GRP/walkable troughing route for @25kV and general E&P/S&T nerds:
Anyway, cheerio from Colton, a.k.a. my therapists chair 🖖

I don't know who needs to hear it, but giving public sector workers a decent above-inflation pay rise is probably one of the quickest ways to turn the UK economy around.
(I do know who needs to hear it, it's Labour shadow cabinet members.)
All the people replying to this saying this will increase inflation: you are wrong and your ignorance is very dangerous. Parrot your Friedman propaganda elsewhere.

Apropos of nothing, here are two maps showing where Britain's high speed rail network should be... Not for the high speed trains, but for the capacity they'd release on heavily congested existing railway lines. #whyHS2 ImageImage
What are those maps? They show average daily road flows (the second one is for HGVs).

This is straight out of @safemyth's excellent report on HS2's carbon benefits: #whyHS2
The sooner we paint a permanent, long-term picture of what our transport systems should look like, the sooner we can build them. Yet only one major party in the UK has attempted to even get close to doing this (the @scottishgreens).

Nothing is stopping @UKLabour doing this NOW.

Let's talk about this #Gadgetbahn: the Padova t̶r̶a̶m̶ guided bus.
Firstly, let's get the important question out of the way... What is it?

If the branding of the system is to be believed, it's a tram. Spoiler alert: it isn't.
Because a glance under the sideskirts and at the roadway reveals that the branding is fibbing: the vehicles are supported on rubber tyres, and the single steel rail only acts as a guideway.

I seem to be seeing a lot of these ex-@EddieStobartCom (?) boxes at the moment... Plus these wagons are German, so these will have done a long trip at some point.

Also: retrofitted side-loading ISO boxes? Clever if so!
From the top...
Never let anyone tell you the railway isn't green, etc... ImageImage

There's easily a full #RailNatter episode covering how wrong everything in this tweet is...
For starters, the ECML was resignalled in the 1950s with one of the most sophisticated power signalling systems in the world, and then again in the 1990s with genuinely world-leading solid state interlocking (SSI). Since then, further incremental upgrades have continued. Image
For the most part, this is why ETCS offers little in the way of capacity benefits on the ECML - four aspect signalling already provides minimal headways between trains.

Only new tracks (HS2's eastern leg) can provide a real capacity uplift - and @grantshapps cancelled it. Image

Well, the #IntegratedRailPlan (a.k.a. #RailBetrayal) has landed. And immediately we can see that their plans are just a re-announcement of things that have already been planned (or indeed cancelled):
Actually, the proposals precisely mimic the NIC's Rail Needs Assessment from last year, despite government decrying it loudly after its publication.

If you want to understand why those plans were bad, I wrote about it in reasonable detail: #RailBetrayal

Good god. You know what? It isn't possible for me to thread this document as I'd planned to as it is genuine top-to-bottom bullshit. #RailBetrayal

This paragraph, for example, is completely untrue. How on earth did the HS2 plans prevent electrification? This is fiction!
