Well
obviously. It's a well-known scientific fact that only 1.8% of the work involved in creating a signal-less, automated, real-time, on-screen, in-cab driver information and warning system is devoted to making the real-time, on-screen, in-cab driver information and warning bit work. How could you not realise that?
"We are currently focusing on addressing safety critical issues identified during the trial run in February,"
Safety critical issue = "I can't see the f***ing screen."
Solutions:-
Virtual display helmets a la fighter pilot
Blackout the cabs and give the drivers a video display of the track ahead as well as an
ERTMS▸ screen
Dump the drivers and drive the trains using X-boxes from a central control room in Machynlleth. I'm sure we'd all volunteer for one trip a week.
