The Electrification of the Pioneer
Underground Railway in London

(1) In the 1890's the pioneer steam-operated Metropol­itan Line in London began to lose its importance due to the competition of the newly built electric tube railways. So it was a vital need for the Metropolitan to introduce electric haulage.

(2) To show the valuable benefits of the electric rolling stock for this line it was decided to test a m-u train. In the course of the experimental runs the train demonstrat­ed its ability to eliminate air pollution. Besides, it could accelerate rapidly and thus proved more advantageous as regards speeds. The next step to be taken was to choose a power supply system. Most engineers spoke in favour of the low voltage d.c. to be fed to the trains through the conductor rail.
(3) The electrification of the Metropolitan Line complet­ed, multiple-unit trains composed of well-lit saloon cars (вагон-салон) were brought into use. In spite of the costly reconstruction work, electric haulage made it possible for the Metropolitan Line to win back its passengers.
