You have to use forward_stop and backward_stop if you combine the two
directions in one relation, otherwise the same-named stop in the two
directions don't get combined on the line diagram. I think if you use
two relations, one for each direction, it combines them regardless of
role (and even if there's no role).

{I don't know what it does if there are both platform and stop nodes -
possibly puts them both in}
