This paper investigates the role of supercapacitor technology in enhancing traction efficiency and reducing infrastructure costs in metro rail systems by replacing conventional track-based electrification. Traditional metro systems rely heavily on continuous electrification through overhead lines or third-rail systems, leading to high capital expenditure, complex infrastructure requirements, and significant energy losses, especially in urban environments with frequent stops. Whereas, the quick charging, adequate regenerative braking, and longevity of supercapictor powered trains enables them preferred choice for local railroad lines.

Abstract: This paper investigates the role of supercapacitor technology in enhancing traction efficiency and reducing infrastructure costs in metro rail systems by replacing conventional track-based electrification. Traditional metro systems rely heavily on continuous electrification through overhead lines or third-rail systems, leading to high capital expenditure, complex infrastructure requirements, and significant energy losses, especially in urban environments with frequent stops. Whereas, the quick charging, adequate regenerative braking, and longevity of supercapictor powered trains enables them preferred choice for local railroad lines.
