With the litany of excuses about why passengers have to be kept on the concourse until the last second, one wonders how through stations that are major termini, such as Leeds or Newcastle, seem to manage without issue.
It seems the principal Euston issue is about management of resources, something which a different management could be expected to address. The quoted new expenditure may seem attractive, but Euston really needs new procedures, rather than having all the money scooped up by suppliers of assets, whose salesmen must now be licking their lips at what they can flog there, regardless of whether it makes any improvement to things or not. One is reminded of airports which take 30 minutes to get through security while five of the eight security checkpoints are unstaffed, coming up with a solution - to buy more checkpoints.
Back at Euston, new seats by the truckload are possibly attractive, we will have to trust they are not sited somewhere where you can't see the departure screens. Management of the train cleaning staff so they are ready as the train arrives rather than reporting job completion 5 minutes before it leaves again, and similar issues, do not really seem to need £50m to handle.
