[Tagging] Railway routes in different directions.

[Richard Mann]

The "proper" way to do it is to have separate relations in each
direction, probably named for the origin and destination (ie not
calling it the up Bristol and the down Bristol, but calling it the
Bristol-London and London-Bristol service).

Alternatively, put all the ways in one relation and put roles in for
ways which are traversed in one direction only (forward if it's the
direction of the way, backward if it's the opposite to the direction
of the way).
