Yes, while the Docklands Light Railway (DLR) in London is famous for being a fully automated, driverless system, the trains can be driven manually by a member of staff in specific circumstances. Every DLR train has a hidden control console located at the very front and back of the carriages under a locked panel. During normal operations, the trains are controlled by a central computer system, and a "Passenger Service Agent" (PSA) moves through the train to check tickets and assist passengers. However, in the event of a system failure, emergency, or during specific maintenance maneuvers in the depot, the PSA can unlock the front panel and use a joystick and various buttons to drive the train manually at a reduced speed. This is why you will sometimes see staff standing at the front of the train during disruptions. For the general public, the lack of a traditional driver's cab is a major highlight, as it allows passengers to sit in the very front seat and pretend they are "driving" the train through the skyscrapers of Canary Wharf and the tunnels of East London.
