Hi,
The documentation states public transport alerts are in GTFS format. However, looking at the format of the ferries body response, it does not appear so. For example this is the following response body to a call I just made:
1.0����h
$64575fd6-09aa-4764-8e24-90bc3c46ed5c*@*
SFCIB
R
Wharf ClosedZ
Birchgrove Wharf Closed
Is there infact an API that returns this data in the GFTS realtime format (GTFS Realtime Reference | Realtime Transit | Google Developers)?
