South Lancashire Tramways was a system of electric tramways in south Lancashire authorised by the South Lancashire Tramways Act of 1900. The South Lancashire Tramways Company was authorised by the act to build over 62 miles (100 km) of track to serve the towns between St Helens (now in Merseyside), Swinton, Westhoughton and Hulton Lane where the Bolton Corporation system ended. The system was the largest standard-gauge electric tramway outside London.
The company had difficulty raising capital and at the end of November 1900 its shares were acquired by the South Lancashire Electric Traction and Power Company. It also acquired the shares of the Lancashire Light Railways Company and the South Lancashire Electric Supply Company. Construction began in late 1901 and in October 1902 the first section from Lowton through Leigh and Atherton to Four Lane Ends at Over Hulton opened.
