Hidden planet

leave a comment »

On 4 May the Beleben twitter noted that no updates to the HS2 PLANET forecasting model had been published since July 2017.

twitter, @belebenso, 'PFM 7.1 is July 2017 IIRC, after which publication of updates ceased without explanation.'

The Department for Transport has now confirmed that it is unwilling to publish these updates, apparently because none of them have been ‘fully checked and assured’.

DfT, HS2 Planet forecasting model updates are being withheld, May 2020

So, the forecasting model updates are apparently ‘assured enough’ to ‘inform’ the decision to go ahead with HS2, but not ‘assured enough’ to be perused by the public.

'Er, quite remarkable, actually' (David Coleman)
