Sure. Tram stops often work like this in Europe. I think in that case
it could be one Stop Point given that one waits in exactly the place
to go in either direction or two different ones. I would be relaxed
about both. If there were two distinct shelters or the platform was
wide then two might be justified. There is a complexity with railways
where there is often one platform for two track, and in these
sometimes the platforms are divided into sections. For example where I
live one side is platform 3, and the other is platform 4a,4b and 4c,
this would require four Stop Points. If, however we as a principle
follow the EU Transmodel standard for these features, then we will
find that there is a solution to all these special cases, including
hail and ride and trains that separate.
