Melbourne Airport is going to be as busy as Heathrow, so why the argument about one train line?

摘要

Public discussion of rail links to airports has been narrowly focused on the idea of a single line and where to run it. In Melbourne, the politics of this debate has so far prevented a railway from being built, because it is not possible for one line to meet all of the landside access needs of the airport. If we want anything to happen at all, we must move beyond barracking for one or other route. We have to recognise the need for multiple lines to serve everyone's needs. If we look further afield, of the world's top 20 airports, 16 have rail access, 14 have integrated metros as part of the commuter rail network and four have multiple connections: London Heathrow; Tokyo Haneda; Shanghai Pudong and Bangkok Suvarnabhumi.
