Inexactitude of additionality

leave a comment »

Scotland will benefit from 34,000 additional seats per day from London when HS2 is completed in 2033, according to Rail magazine.

[‘HS2 offers thousands of extra seats to Scotland’, Richard Clinnick, 13 Sep 2017]

Secretary of State for Scotland David Mundell revealed the figure in a Commons Written Reply to Alan Brown (SNP, Kilmarnock and Loudon), who had asked three questions relating to HS2.
[…]
He said the business case assumes two 400-metre HS2 trains per hour between London and Scotland, and that these will split or join at Carstairs, with half serving Glasgow and the other half serving Edinburgh.

[…] Each 400m train is assumed to have 1,056 seats.

“Assuming 16 hours of departures per day, the services assumed in the business case would provide a total of 34,000 seats between London – Glasgow and London –
Edinburgh on HS2 in both directions each day,” said Mundell.

Rail magazine, '34000 additional seats per day to Scotland from London when HS2 is completed in 2033'

“Additional” means “supplementary to what is already present or available“. The story does not say what London – Scotland seat capacity is already present or available, or what would happen to it when HS2 trains started running.

Of course, it is not at all necessary to spend £60 billion to increase Anglo-Scottish rail capacity. Furthermore, as a percentage of total UK passenger traffic, the volume of cross-border travel is chicken feed.
