Metropolitan Electric Tramways

The first section of line was opened on 22 July 1904, with services from Finsbury Park to Manor House (where a connection with the London County Council Tramways was made) and Wood Green.

The network was rapidly expanded between 1905 and 1911, MET having gained powers to build its own lines as well as operating those constructed by the county council, and by the acquisition and electrification of the North Metropolitan Tramways Company's steam-operated line from Wood Green to Ponders End.

On 1 January 1913, MET became a subsidiary of the London and Suburban Traction Company (LSTC), jointly owned by BET and the Underground Group.

At that time, company owned 316 tramcars, and 9.38 miles (15.10 km) of track, with the remainder being leased from Middlesex or Hertfordshire County Councils.

The outer termini of the MET network were Acton (where it connected with the LUT system), Sudbury, Canons Park, Barnet, Enfield and Waltham Cross.
