Following the success of this test the Metropolitan Railway pushed ahead. A 3kV AC overhead electric system was considered, but in the end the Metropolitan decided to stick with DC conductor rails as was being adopted by London's other electric railways (and of course is used to the current day). The stock for this initial phase of electrification was built in three batches, known as the 1904, 1905 and 1906 Stock. A mixture of motor cars and trailers were built, open lattice gates used for passenger access. The initial batch of trains used Westinghouse electrical equipment though later units used more powerful British Thomson-Houston GE69 motors.
The units began operation from Uxbridge to Baker Street in 1905 [2]. The trains had first and third class seating. The open platforms proved to be troublesome in the open air parts of the line and were covered over after a short time [3]. Central sliding doors were also added in the early 1910s. One trailer has survived into preservation though is still in a poor state.
