So the time by air was much and such the same as the train from Edinburgh.
Ok try now to do it from Inverness or Aberdeen or even further north. To get to Edinburgh from Inverness takes about 3hrs 30mins and from Aberdeen about 2hrs 40mins.I think the plane would win hands down.
Check in at inv or Aberdeen airport maybe 1.5 hrs later on your aircraft in London 1.5 hrs later pick up your bags 30mins and train to central metropolis another 30 mins total on a good day 4hrs, the train would'nt even be at Berwick
But of coarse if the Govt had their way,(be it Thatchers Tory or Blair/Browns Labour), Scotland would be desolate from Edin/Glas north
