Some of things it shows for Manchester are not buses (i.e. metrolink). Where does the data come from? Edit: also Flixbus or National Express are arguably not a bus services either

Other websites for "bus times" that show the NL2 ferry service from Aberdeen to Lerwick say their data comes from the Traveline National Data Set (TNDS): https://www.travelinedata.org.uk/

> TNDS contains public transport timetables for bus, light rail, tram and ferry services in Great Britain.

For Aberdeen it shows me a bus to Shetland, quite an exciting prospect
