> Minimal or no usage of digital electronics

Everyone in this thread seems to be forgetting that those might be useful and not just fancy toys. I prefer trains that have digital signage indicating their location, and connections at the next station. Higher level of automation in trains (e.g. Communications-based train control) also drastically increases efficiencies in speed and scheduling, allowing more trains on the same tracks, and minimises time wasted waiting or accelerating/decelerating needlessly.

The problem is poorly implemented software, not the existence of software.
