I have a clue about what your posting. Lies!
shall i inject some facts to the best off my ability
i was a train driver man and boy for nearing 25 years yes it was nearly 20 years ago when i got the sack on the southern region BR
the tube can on certain line be fully automatic but not on open stretches
within the tunnels you will always need staff for evacuations in case off mishap /failure
on the nation railways
the amount off training depends on route miles and complexities types off traction and [different locos and units] and different train types] passenger freight engineers stone etc]
the minimum will be less than a year with some taking in excess off 2 years to fully cover all traction and routes covered
as an aside when i first started on the footplate in early 70s you drove your train in the dark with no lights only 2 or 3x15w marker lights so people can see you coming
you had to know exactly where every bend speed restriction and station is in the dark and apply the brakes up to a mile away to stop
