Metro trains are powered by an exposed electrical cable also known as the third rail, that runs alongside the train vehicles' two rails. Because the exhaust in enclosed train tunnels as well as stations would induce carbon monoxide poisoning, the metros do not use hydrogen combustion engines. METRO is made up of a microprocessor, an RF receiver, and a speech recording chip with a speaker. The car is connected to the entire system (Train). The train moves when the project is energised until it comes across an RF card put beneath the track.
