The Docklands Light Railway (DLR) in London is a sophisticated automated transit system that operates without traditional drivers in the front cab. Instead, the trains are controlled by a central computer system that manages acceleration, braking, and station stops via high-frequency radio signals and track sensors. Despite being "driverless," every train has a Passenger Service Agent (PSA) on board. The PSA's role is to verify tickets, operate the doors at stations, and take manual control of the train using a hidden panel if there is a technical fault or emergency. Because there is no driver's cabin, the front and back of the train feature large windows, allowing passengers to sit at the very front and "drive" the train through the skyscrapers of Canary Wharf. The system is fully integrated with London's Oyster and contactless payment network, and all stations are step-free, making it one of the most accessible and technologically advanced light rail networks in the world.
