The proposed station is intended to link Kent International Airport (Manston) to the Southeastern High Speed rail service. Somehow. On the left is Southeastern Network's map of their routes (click it to big it).
The pale grey track that loops out from the existing Eutrostar route between Ebbsfleet and Ashford is the new high-speed rail link, taking in the Medway towns, the north Kent coast, Thanet and Canterbury. We are being promised shorter journey times from December 2009.
The map's legend has a symbol for Airport Interchange, notably missing from the Ramsgate area, for the simple reason that the Interchange or Parkway Station doesn't exist. Here's the high-speed link on a conventional map: the route is the blue line; the blue pins are stations; the red bits are explained later. Click here to see the full Google map.
Which brings us lumbering to the inevitable question: where will that little Airport Interchange symbol go? Where will Manston Parkway be built? The strategy document is curiously non-committal, but suggests somewhere in the vicinity of the airport (sensible) and the Eurokent Business Park and Westwood (mad).
In this close-up of the earlier map, the red pins are the Manston Business Park (MBP) and Westwood, the red block the runway, the pink area around it the airport site, and the little yellow blob the Passenger Terminal.
Introducing MBP/Westwood into the calculations is bonkers - it instantly creates more problems than it solves. Let's assume instead that the airport is the sole driver. Dear reader, if you ran the world, how would you get passengers from the airport onto the high-speed link?
In terms of practicality:
Whichever solution is chosen, there is still the problem of the cost of the train journey. Rail fares from Kent to London are (unreasonably) expensive, and the high-speed service will apparently be 10-20% dearer still. This doesn't sit easily with a business model based on high volume, low budget passenger traffic - the train ticket could be costing as much as the plane ticket.
Local tourists, drawn from the airport's catchment area, are more likely to drive to the relatively cheap car park at Manston. Foreign tourists heading for London can choose from other airports that have cheaper connections to the capital. I don't see Manston Parkway Station being built. Do you?
