DC Traction

DC traction refers to the use of direct current (DC) electricity to power electric trains and streetcars. Instead of using alternating current (AC), DC systems supply a steady electrical flow through overhead wires or tracks, allowing vehicles to draw power directly for propulsion. This method enables precise control of vehicle speed and acceleration, often used in urban transit and vintage systems. DC traction systems are valued for their simplicity and reliability, especially in shorter, fixed routes like city subways and tram lines. They require substations to convert grid AC into DC and infrastructure for effective power delivery.
