Quote: "With reference to the station at Teesside Airport being closed it has remained open, albeit with a summer Sunday service of one train each way, presumably this being cheaper than all the legalities of closure. According to Wikipedia 'with 18 passenger entries and exits between April 2010 and March 2011 Teesside Airport is the least used station in Great Britain'. Whilst the airport is DTV Airport the station is Tees-side Airport (with the hyphen) on the National Rail website!"
Interesting, believe that's what is technically known as a "Parliamentary" train. However, even if the station is de jure open for one train/week, it is de facto closed, because all but one of the trains don't stop there. That makes it worse than useless as an airport station.
Quote: "On the other hand Kidlington is sandwiched between LHR, LTN, BHX and BRS not to mention others such as Gloucester, anything more than a 30 minute drive from Kidligton then far more convenient to drive to one of t'others which will offer better services, schedules etc."
In the unlikely event of small scale operations or a LCY-style set up at NHT, would OXF survive? Could the two co-exist?
