At the moment I'm making a map of public transport in the UK. And I need to know what to include. Obviously trains, buses, ferries, trams etc are all public transport. An argument can be made for taxis, but they don't run to a set schedule like trains or buses. In rural areas like Lincolnshire I'm aware on-demand minibuses (demand-responsive transport) run to remote villages, would these count? How about the minibus to Cape Wrath? Unlike a taxi, this is set to run 7 days a week from Easter till October but doesn't run to a set schedule as it relies on the Durness ferry operating, which can operate at different times due to the weather or sometimes not operate at all. And then there's heritage railways. Anybody can purchase a ticket on these railways, but their main purpose is for leisure. If these are included what about, say, the Ruislip Lido railway? This might be a stretch and personally I wouldn't include this but it could be used for other purposes than leisure. How about people-movers at airports, like the ULTra system at Heathrow, or the AirRail Link at Birmingham Airport? What are people's opinions on what should be considered public transport?
