Thank God Arriva have left Wales.The GTFS was fetched from transitfeeds or
transitland in the last year. The problem with both these services, and the far
more usable and original GTFSfeeds for that matter, is there's no real reason
to put yourself on there other than geeks like me might be able to get hold of
it, and no real reason for the service to be maintained anyway. I cant believe
any production outfit is using these services as part of their data flow unless
the service provider uses that same data for their own products. I'd like to
think BuzMap would make a decent frontispiece to any directory and allow you to
download a GTFS by clicking on it's footprint, and list all GTFS in an area by
dragging a box out perhaps. One of my tasks is to flesh out the provenance and
fetching/update strategy for the GTFS import. I can then start pointing to more
reliable sources per individual feed. I could then turn this into a GTFS
directory myself. I mailed 3 tiers of people, the UK Dept of transport project
to get buses GTFSed, an EU level body that is essentially promoting the same,
and there's a world body wanting to "increase bus usage by 100%". If you know
anyone in any of those entities, say hello. The core idea works, there was
enough easy data in Europe to prove this. I can do Paris, and I can do whole
countries like Holland, I am scared of nobody :). NYC will look awesome with
the ferries to boot. But I am far more interested in getting this to work in
areas outside of North America and Western Europe, unless someone is going to
make it worth the effort.
There is only one instance of any trip pattern, so you only get one instance of
a timetable. Doing complete timetables ultimately requires route planning and
merging of common routes. Deploying a trip planner for all this is going to
take kit obviously, loads more space, and it's just replication of what has
been done many times already. My view on this is that it's a separate job, the
trip planner can use my tiles. I need to make it clear its just the stop order
and change the times to time differences, maybe include the first and last
departure times. I'd like it to tell the truth and give you all the times, but
it's a major job obviously.

You still have Arriva Trains Wales as the train operator for Wales and
Borders, it has been Transport for Wales for well over a year.
Also not fully understanding the times, are they supposed to the next train?
