Which mrt is the most hightech underground heavy rail in the world?

Question

which country had the most advance underground mrt in the world?

Answer 1

Not sure what you are referring to, no railroad has strictly underground operations, metro and innercity systems for primarily passenger hauling are the only ones that I am aware of.

Answer 2

It mst probably the line nbr 9 of Barcelona´s (Spain) underground: fully automatic, no driver, superwised by electronic from a central command post.

Answer 3

in  my opinion, of what I've experienced the Docklands Light Railway is pretty cool as the trains are computer controlled and you can sit at the front where the driver usually sits
