[Talk-transit] Public Transport routing

The question for me is: could OSM fill in this 'gap' of functionality that
Google Transit has?

There's an old conversation at
http://wiki.openstreetmap.org/wiki/Talk:Train_routing about whether train
routing could work without a timetable.

Whilst having a full timetable would clearly be better, I think we could do
a fair bit without it.

For instance, if we mapped the all train services (using relations) where
the frequency is generally one-per-hour or more, then we could at least show
people searching for a route which trains they can get, and where they'd
have to change. Then they could look up the times for themselves on
trainline.com or similar if they need to. The advantage of us doing this is
that we can show public transport routes alongside car or walking routes.

There are quite a few circumstances I can think of where you don't need to
know the exact times in advance, just that a route is possible. For example,
if you're planning a holiday, it's helpful just to know which places you can
get to by train.

It would even be possible to do things like selecting a station, and then
displaying all the stations you could travel to from there without needing
to interchange.

These are the things that get me excited anyway. Sadly, I don't have the
expertise to build any of them...
