If you know the city (whichever it is) it probably is easier. But how about
people who have just got off a plane at Heathrow and there are two trains
sitting there, one with Cockfosters and the other with Arnos Grove on the
front and you want to get to Morden (say)?


But I didn't know the city when I first arrived there, how could I? And
what is a journey planner for, in any city (why, oh why, was the New
York one so confusing?) but to find out how to get from A to B.
