RAIL travellers between London and Glasgow can save 85 per cent on the standard fare during the month of June. The full rail fare is pounds 126, but if you book two weeks ahead (0800 450450) to travel on the first or last train of the day, or the overnight service, a 'CrazyApex' return - nearly 800 miles of travel - will cost you only pounds 19.

The InterCity West Coast division, which has run the London to Glasgow line since the break-up of British Rail, has chosen this way to publicise its increased summer frequencies.
