These Japanese style train sims are quite a bit less realistic, including fewer signals you need to know (Densha de GO!! essentially only has speed limits, g-forces, train load, and weather modeling.) and simplifying the controls to essentially a single handle that goes from full brake when pushed all the way forward to full traction when pulled toward you, with a switch you need to press to be able to pull it past neutral.

But in return they add very technically difficult tasks, such as stopping within a millimeter of the stopping point within a second of the time in the timetable without re-braking or making passengers uncomfortable, or stuff such as pointing at signals. They even add completely unrealistic stuff just for the sake of gameplay such as bonus zones where you need to stay at an exact speed, sounding the horn for overpasses and level crossings, or dimming the lights for oncoming trains.

They "feel" very different to games like Train Sim World, but I like them both regardless.

It hits that mid point between complexity and simplicity. You can kind of chill out but without the process becoming too mundane.

Imagine if we can replace all the locomotive drivers with pensions with retired software engineers who literally will pay to do the job remotely? Even better if there is a prediction market and twitch stream on top with bets for the most mundane things.

edit: This actually sounds awesome
