subway trains

Subway trains are electrically powered vehicles designed to operate on underground or enclosed tracks within urban areas, providing efficient mass transit. They run on dedicated rails, often in tunnels or elevated sections, and are accessible via stations where passengers board and alight. Subways are engineered for high-frequency service, enabling quick, reliable transportation across city neighborhoods, reducing traffic congestion. They utilize complex signaling and control systems for safety and coordination. The trains typically consist of multiple connected cars with seating and standing room, designed to carry large numbers of passengers efficiently in densely populated urban environments.
