As Angus said, it was a past convention. I suspect it arose during the
golden age of rail travel, when the 'up' line was the line which led to
the
main terminus, regardless of either gradient or comparative latitude. On
any
English main line connecting to London, therefore, one travelled 'up' to
London. Nowadays, the convention seems to have fallen into disuse.

Thankfully not on the railway. Most times, the trains seem to know which
track to be on....
