I am back in London for a couple of days before heading off for an idyllic week's walking! One of the first things that struck me was the old British Rail logo that you still see when you get on the train at Stansted.
It really is a design classic. (as said here). What really struck me is that you know what it is, without having to think what it is. It makes use of elements of the product itself - in this case the rails; delivers a sense of what the product delivers - movement; and above all presents a clear sense of an entity which has a sense of purpose. The latter is actually more than what now adds up to British Rail does, but hey ho! the logo is still around and maybe sometime BR will be back.
