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?

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@Molombo8998 @philatrail Obviously not at a visual speed that would enable the train to stop.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@mdw1989 @BBCTomEdwards In that case an entire train would have to board/embark at Stratford. That could take as long as it does at St Pancras.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@BBCTomEdwards Stations on HS1, like Stratford, have much lower platforms than the UK 'standard'. It makes boarding much slower. Needs massive ramps for some. It was built to the EU high speed standard. HS2 was supposed to be the same. It was nuts.

@RegenerationEX @Farnsworth100 @juliathrift @mtpennycook @SharonStevenage @peteraf1 @NickyGeeson @sheilaoliver16 @CaitlinHafferty @NewCor18146 I have read too many of those. It seems the Government can't see the problems staring them in the face.

Most new roads are to facilitate more car-dependent sprawl. Any relief they provide will not last long & more traffic will make things worse elsewhere. We shouldn't be building roads to add more traffic.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@mcahs2 It seems like a signalling fault was a possible cause in this case but they don't go away. Things break.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@mcahs2 If anything goes wrong then it's going to be much worse at high speed. Far worse still if two trains are involved going In opposite directions. Tracks are not separated enough to avoid that happening.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@mcahs2 @BBC is reporting that one train was stationary & the other one was traveling at speeds 'up to 200km/h'. That is the speed our diesel HST trains travelled at in 1976. HS2 was designed for twice that speed. It's completely nuts, utterly pointless & ridiculously expensive.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@Captain_Deltic I have long been trying to understand how HS2 trains would actually brake under ETCS. There is just one flag for 'low adhesion'. How 'professional' is that? Who decides if it's on or off & when?

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@TransportActio2 @TANCymru It was all in the 1994 SACTRA report on Trunk Road Assessment. Building more roads creates more problems than they solve. One of the worst is new developments built in unsustainable locations with no alternatives to the use of cars. That's what the planning system is delivering.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@Hrushworth I know a new railway bridge with five types of fencing. It doesn't cater for cyclists or pedestrians & it's tight for two large vehicles.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@ElaineCox11 NPPF is nuts. It is utterly stacked in favour of development on greenfield land where it is not possible to provide genuine alternatives to cars. It is still not viable because speculators extract the land value gain & essential facilities don't happen. Transport not considered.

@Feargal_Sharkey Where does the money come from to pay the fines?

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@SmartGrowthUK Public transport still hopeless compared with standard European practice.

@Farnsworth100 @GreenRForest @HillRams @NickyGeeson @HereforHereford @CommunityPlann1 @northyorksc @RosieP4 @stellastafford @peteraf1 @BEAG_Tweets @NewCor18146 @greenarteries EIAs which consider traffic impacts usually use ISEP guidance which refers to a specific increase in flow. When roads/junctions are congested flows can't increase so threshold are not met & the EIA will say there is no Environmental. impact. Yeah right!

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@AlastairDalton @TheScotsman What's the point of running a diesel train from Stirling to London?

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@greenarteries Don't believe it. Poundbury is right next to the town of Dorchester & is not like anywhere else.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@MichaelLCrick It shouldn't be up to local councils.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@philatrail An utter waste because of the pointless specification & the constraints of putting a massive junction is such a stupid location. It would have been cheaper, shorter & faster to tunnel directly into Birmingham. Or just don't build high speed lines into cities - like others do.

[John Marriott 🍃💚🍃🚲 @HS2theTruth]

@lfg_uk The High Speed Line HS2 is costing around £7bn/yr for just 120 miles of track with an unknown delivery date. We have governments that like wasting money. It doesn't help that they have almost no knowledge of engineering or the laws of physics.
