The HS2 trolls come out to claim HS2 is Green. Not one of them has ever come up with a justification for designing a railway for 250mph. It's the major factor why it is so expensive & so destructive. The carbon deficit of its construction & width needed is greater than a motorway

Can #HS2 opponents please RT this and show it to anyone who still argues for it?

@DuncanStott The challenge of driving trains automatically is trivial compared with driving road vehicles. For a start there aren't that many trains compared to road vehicles, they do not need to steer, they try to run to timetables & many don't mix with pedestrians & cyclists.

@MATatBucks @LGACons @JamesCleverly GB has worked but remember Green Belt was just a discretionary local authority decision - mainly in the 50s.
Most of England did not see that land at least as valuable as that designated would be threatened & didn't bother. Much now fast disappearing by being covered in sprawl.

@ElaineCox11 'Only' 570,000 sq.m. Getting of lightly compared to the M1/M6/M42 area logistics operators / developers call the 'Golden Triangle'. DfT/National Highways asleep at the wheel as motorways & junctions are turned into conveyors.

@BobFromAccounts @DuncanStott It's everywhere. Not just London.

@youngwt @lfg_uk @AaronBastani Cities built & ran trams & buses. It was something they could do & it was vital until cars appeared. No-one seemed to realise that cars would create congestion. That led to sprawl & more traffic. It has destroyed cities unless they have an efficient public transport system.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@lfg_uk @huggymike @AaronBastani Many cities & large towns used to have trams.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@lfg_uk @__karl__ @AaronBastani We chose to go for sprawl & made local public transport fail because it could not be integrated or integrated with trains. Blame barmy politicians & the CMA.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@jfwduffield HS2 did not have to go in a straight line. It just needs extremely large radius curves because of its pointless design speed. That means it can't work around the topography & other constraints. It destroys them & takes more land. That is very expensive.

@HereBeProof @DanicaPriest @lfg_uk @AndrewW66619812 The existing railway line didn't need a 'bat tunnel' & trains running at conventional express speeds could have used it.

@brownliberite The 2009 estimate for Phase 1 after a few months was £12.3. It was produced in 6 months *.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@Beezus37644877 @tomhfh Most people want more reliable journeys & cheaper fares. HS2 is wasting £100bn+ to stop that happening.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@sands659 @albiondumsday @tomhfh Should have picked a lower speed & a different route but really it was the wrong project driven by people who didn't know what they were doing & didn't care.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@nigethugrug @albiondumsday @tomhfh Those foundations are going to move. Look at most roads. HS2 thinks they won't & it has spent £bns already in the process.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@iainlindley @albiondumsday @tomhfh It would not look the mess it does if a lower speed had been chosen. It could avoid problems & people. It is a ridiculous price to pay for a worse, unconnected railway.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@albiondumsday @tomhfh HS2 said the additional tunnelling was mainly to save cost & risk. It failed to appreciate the problems of the original 'design'. Also claimed reduction in delay. Looking at the rest that looks true.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@NoelDolphin Isn't that the standard? Unfortunately when some road bridges are raised to facilitate electrification they are not even widened to permit even one footway or a standard carriageway.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@Modern_Railways Totally bonkers to allow diesel passenger trains to use an electrified WCML. It's obviously not full. It seems Chris Gibb doesn't know 300 Amps won't propel the trains he likes at speed up a hill or on the flat?

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@philatrail ETCS looks ridiculously expensive for what it does. It's not much better than Victorian tech & should be obsolete. It still works in steps & needs a driver to look at something & take the right action.

How can it possibly cost £500k to fit something in a 66 & then not work?

[Steve Jones @SteveJo72541188]

@HS2theTruth @TransportActio2 Backhanders and corruption into the pockets of decision making politicians and their supporting advisors must clearly be at play within current UK decision making.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@volatrader @giulio_mattioli That's what four tracks do. Or two pairs where it makes more sense. Larger stations need fast and slower trains.
