Not quite sure stopping smoothly and accurately is anything special, you even need to do that in a car to avoid a shunt.
The train steers itself, the internal alarm warns of the signal status, the dead man’s handle will stop the train so I would have thought the hardest thing to cope within on a train is boredom.
You obviously don’t have a train set.
I have to operate , the trains, beware of derailments, operate the signals and junctions and avoid other trains being on the same track whilst the trains are in motion, all simultaneously, none of these are the responsibility of the train driver on the real thing
Oh and I am none unionised, so my trains are more reliable and run on time.
