Actually, why aren't there fully autonomous freight trains on railways yet? We have driverless commuter trains (Docklands Light Railway) why not the same for long distance freight? The infrastructure is there - automated signalling devices in cab, it doesn't seem too big a leap. One hurdle might be unions, I recall ASLEF or someone got upset about the DLR when it first appeared?
