Then you have the fact that time tables depend on the day of the week,
that the route depends also on the day of the week, and on the time of
day, and ....

It's a big project in itself.

Rather than try to centralize everything we know about the world into
OSM, we would be better off figuring out how multiple databases can be
tightly connected.
