Nonsense. If all I know is that my destination is on the Picadilly
line, I'm not going to get on a random train at (say) Victoria) and hope
it's going in the right direction. That way lies Brixton and Upminster
and other forms of depravity. No, I'm going to look at the damned map.

Yes, but I didn't going to say what *you* were going to do. You probably
don't need a message telling you to take your belongings when you leave
the train either. The announcements aren't designed for David Cantrell.

In any case, it is easy enough to know which direction to go at the
start (through instructions or otherwise) but forget which station you
want to change at en route. I know when I waas initially unfamiliar with
the Tube, I got on a train in the right direction but then sometimes
forgot my interchange station. The difference between a blind person and
me is that I could still look it up on the strip map inside the train.
