So do I. But we have a network designed by the Victorians, not Elon Musk. The future will come - I started work at a small outstation called Hough green, in the absolute middle of nowhere. There was a clerk (me), 3 x leading railmen, a platelayer gang of 12 trackworkers, and even a 'Lamp man' whose job it was to go out each day and top up all the signals on the line with parafin. The last time I popped in there 30 years ago there is now just one A supervisor who does everything from selling tickets to painting the lines on the platform. Not even sure they have him now.
Point is that railways have adapted to mechanisation and modernisation, but always on a basis of voluntary severance and retraining. But I will say this - The last time my disabled, 73-year-old sister came to visit me we planned her journey from Liverpool to York knowing there were staff from platform to platform. An incredible amount of non-commuter traffic is like this that of disabled and 'vulnerable' passengers, and thus the promotion of leisure cards such as your Senior Citizen card, Disabled railcars and even family railcards. It's often asked, "Would you get on a pilotless, automated plane?". Most people of our generation would say no, but I expect my daughter's children will find it commonplace in 50 years' time. A better question is "Would you get on a plane with no staff at all on it, nor airport staff at either end, even if everything was fully automated for the able-bodied, tech-savvy passenger? That's the real question. It will happen, but perhaps not too quickly, too soon.
