On-train systems will stop the train in case of failure.
I was responding to “Why not have people in a control room drive the trains, coordinating the system as a whole”. Infrastructure and timetables are centrally coordinated (or actoss several centers). Controlling a train remotely introduces multiple points of failure:
- connection lag
- connection quality
- remote operators don’t have the full details on a train (unless you have one operator per train)
Remote/automatic control works in smaller systems (such as subways, see e.g. Copenhagen), but the speeds there are usually smaller, the “fleet” is smaller, you can reach the trains in case of failure faster etc.
