Sir - Here's a green idea. Since Eurostar provides our best means of environmentally-friendly travel to the continent, and since there is already a good frequent coach service between Oxford and London, couldn't the two be linked together?

From the 17th of this month, Eurostar will be running their high-speed trains from St Pancras (rather than Waterloo), so couldn't at least some of the Oxford-London coaches use St Pancras as their terminus?
