I believe there is a big market for First Class as there is in all other countries. Just out of interest is NSW offering First Class seating on their regional services?
Yep and in a 2+1 format. I think it might be called business class instead of first class and because it is diesel electric it will be much more amenable to the passenger with no whining gearbox or engine noise during acceleration.
edit: It is called premium class on the new regional fleet in NSW.
A whining gearbox, which I quite like the sound of and being far preferable to whining passengers, always tells by the sound of the engine and gearbox that when 'top gear' has been reached, the train is travelling in excess of 132Km/h. (tested by many cab-rides)
I actually prefer to sit in the middle of the car where the engine/gearbox noise is, because the sound is good for lulling to sleep on the regular commute and drowns out the whining and not-whining pax.
I never sit in 'Quiet cars' as there's always someone on their phone or speaking loudly because the Quiet car concept doesn't apply to them.
