 The MET operated London's only regular single-deck electric tram services, on two tram lines serving Alexandra Palace.The first line ran from Turnpike Lane, approaching the Palace from the West via Muswell Hill, and was opened in late 1905; the second line opened a few months later in 1906, and started from Wood Green, entering the Palace grounds from the East.On 1 January 1913, MET became a subsidiary of the London and Suburban Traction Company (LSTC), jointly owned by BET and the Underground Group.
