Commuter rail service connects Colombo to its suburbs, helping alleviate rush-hour congestion on city roads. Local commuter trains and intercity lines use the same tracks. Colombo's commuter-rail network is of track from Panadura to Polgahawela via the Fort and Maradana stations. The route is multi-tracked to provide rush-hour service. Electrification of the commuter-rail network has been proposed to improve energy efficiency and sustainability.
