Change to bus line groupings

Our all-day and rush-hour high-frequency lines (buses with departures roughly every 2 to 12 minutes) have a new distinctive visual identity on our STM network information tools.

To represent these 31 bus lines on your app, please use the corresponding hexadecimal colour code shown in the GTFS.
