Why do some DLR trains have drivers?

Question

On the Docklands Light Railway in England, some trains are driven by a driver and others are operated automatically. Why the difference?

Answer 1

All DLR trains are staffed by a "Train Captain" who closes the doors and tells the computer to start the train. However should there be a fault, then that person can over-ride the computer and drive the train at a maximum speed of 20 mph from a normally hidden control panel at the front, under the instruction of the line controller at Wapping depot.

Answer 2

On the DLR and the Victoria Line, there are no drivers. The driving of the train is done wholly automatically.

Unfortunately, we have, as yet, been able to train a computer to open and close the doors safely. So a Train Captain is employed for this menial, but essential, task! They can also override the system in an emergency. (Last month's crash on a european overhead monorail system might have been avoided if they had been present.)

Answer 3

Greyhanky good answer pal.
