There is more to Train Driving?
Understanding your road (Track) is only the beginning of a more complex observation and trust in the signal control centers is the start of being a driver, wither passenger, underground or freight!
The driver must be watching and have good eyesight to obstacles on the road, from engineering workers, to the public and criminal activity, while speeds must be kept to, there are changes at times that have to be heeded?
On the Tube, Metro, Underground there may be slightly different rules, but crossing tracks is out of the control of the drivers and today much of it is in the hands of automation and now A.I. and in the near future more driver less trains will be in service all over the place!
Automation came in because of human error, due to being slack, lazy, but more likely tiredness and the actions leading to serious accidents from the introduction of railways and the underground?
