The item (May 12) on the Sheffield to London train cutting four minutes from journey times started me thinking. What will passengers do with the time saved? Will they have time to go to the loo? Will they be first in the coffee queue? Perhaps four minutes will be enough to buy a magazine (not to read it, though). The important ones will perhaps arrive at their meeting a tad early. What will they do? How much is this costing - all for four minutes?
