South Lancashire Electric Traction and Power Co
South Lancashire Tramways Co 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 Co and the South Lancashire Electric Supply Co. 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.
Atherton became the centre of the system and the tram sheds, power station and offices were built on the north side of Leigh Road at Howe Bridge (grid reference SD 6624 0203)
1928 Atherton Power Station was selected under the North-West England and North Wales Electricity Scheme
