The technology used in metro trains can vary depending on the specific train and transit system. However, there are some common technologies that are often used in these types of trains.
One example is an automated train control system, which helps to manage the movement of the train and keep it on schedule. This type of system can use sensors to track the position of the train and make sure it stays on course.
Another common technology used in metro trains is an automatic doors system. This can help to improve safety by keeping the doors closed when the train is moving, and opening them automatically when it arrives at a station.
CCTV cameras are also often used in metro trains, as they can help to deter crime and provide security for passengers. In some cases, these cameras may be monitored by staff in a control room, or they may be able to record footage for later review.
