It's definitely automatable, entirely. The DLR in the UK proved that. But that isn't going to happen when the problem is slightly more complicated and not predictable like it is in older lines. You have ot build with automation in mind. One tree on the line and an automated train will plough through it for example derailing it and killing many people ( http://www.caerphillyobserver.co.uk/wp-content/uploads/2013/01/Derailment-Brith-Dir-300113.jpg http://www.caerphillyobserver.co.uk/wp-content/uploads/2013/... ) . One dodgy point, it won't notice and won't report it and the next thing you know, the train is going sideways down a platform side-swiping people ( http://www.virginmedia.com/images/potters-bar-crash-431x300.jpg http://www.virginmedia.com/images/potters-bar-crash-431x300.... ) Machines are shit at noticing these things. Also the problem is that it's not just about sitting there and pulling a lever - that bit is quite easy. There are a load of surrounding tasks like checking out the locomotives, coupling, shunting, safety rules, signalling, token exchange (which is still used), diagnosing problems (why aren't the brakes releasing can be an hour to diagnose/fix) and the inevitable "managing drunken passengers and coordinating with police" etc. Not everything is suitable for the lowest common denominator of person or automation.
