Stalybridge, Hyde, Mossley & Dukinfield Tramways & Electricity Board was a public transport and electricity supply company formed by Act of Parliament in August 1901. It was a joint venture between the borough councils of Stalybridge, Hyde, Mossley and Dukinfield. The system was officially opened on 21 May 1904.
At its inception the scheme included 21 route miles of tramway and a fleet of forty tramcars. The network was later extended to 27 route miles with a fleet of sixty tramcars. The rails were rolled by Bolckow, Vaughan & Co, Middlesbrough. The points and crossings were made by Hadfield's Steel Foundry Co, Sheffield. The main tram shed was on Park Road, Stalybridge adjacent to the Tame Valley generating station. Smaller tram sheds were also built in Hyde and Mossley.
The British Westinghouse Co was the lead contractor for the first forty tram cars, supplying much of their electrical and mechanical equipment. The car bodies were sub contracted to the British Electric Car Co, Trafford Park, with bogies from the McGuire Manufacturing Co, Bury and wheel sets from the British Griffin Chilled Iron Co, Barrow in Furness.
