Modern technology is available for driverless trains, thus eliminating human error and passing red signals, though all stations would have to be manned ("Train driver shortage cuts back services", The Argus, November 4).

Modern railway thinking considers changing commuter networks to stopping at all stations, similar to the London Underground. This would enable driverless train operation and increased frequency. To avoid increasing long journey times, extra permanent way track would be needed.

Reduction in air travel has made the Gatwick Express a waste of space. These trains could be used to increase the Victoria to Brighton or Hove to Bournemouth mainline services.

The disjointed Coastway shuttle service railway needs priority modernisation between Bournemouth and the Channel Tunnel, through Ashford International, to take pressure off London commuters and rejuvenate the South Coast economy and bring it up to standard with the rest of the world.
