Driverless trains, also known as automated trains, operate without a human conductor on board. They use advanced technology, including sensors and computer systems, to navigate tracks and manage speed. These trains can communicate with control centers to ensure safety and efficiency, making them a popular choice for urban transit systems like subways and light rail. Many cities around the world have implemented driverless trains to improve public transportation. These systems can reduce operational costs and increase reliability, as they are less prone to human error. Examples of driverless train systems include the Docklands Light Railway in London and the Vancouver SkyTrain in Canada.
