lplsprog - technically no in the IOM we are not subject to UK APD but our govt follows suit and raises it whenever the UK do. We are also subject to VAT so it would make our eyewateringly expensive air travel ( I fly IOM to LCY tomorrow - £360!!) even worse.
west lakes - during this years centenary TT the govt ran commuter trains - yes those 3ft gauge steam engines and the Victorian electric trams - the total number of car users who used the tram service was 1!!
As has been said people outside of large cities travel by what is most convenient - car most of the time or air for longer journeys - Brighton to Inverness by train anyone?
