GTFS-R service alerts for all transport modes are now available! You can browse them all here: https://opendata.transport.nsw.gov.au/node/326/exploreapi#/
Previously we have only supplied Sydney Trains GTFS-R service alerts, and users either had to apply their own matching using the Trip planner add_info API or use alternative feeds for other modes.
The new feeds are supplied as an aggregation of all alerts, and also split up into separate modes - and even trackwork alerts - to allow users to consume as they wish. Note that the pre-existing Sydney Trains alerts feed is unchanged.
In another improvement, the feeds also use the multi-lingual capability in GTFS-R to encode both “language = en” for the plain text version, and “language = en/html” for the html version, which supports richer content and caters for more complicated formatting/linking that can happen in transportnsw.info alerts.
