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).
