London Underground
Electrification

With the advent of electric Tube services (the Waterloo and City Railway and the Great Northern and City Railway), the Volks Electric Railway, in Brighton, and competition from electric trams, the pioneering Underground companies needed modernising. In the early 20th century, the District and Metropolitan railways needed to electrify and a joint committee recommended an AC system, the two companies co-operating because of the shared ownership of the inner circle. The District, needing to raise the finance necessary, found an investor in the American Charles Yerkes who favoured a DC system similar to that in use on the City & South London and Central London railways. The Metropolitan Railway protested about the change of plan, but after arbitration by the Board of Trade, the DC system was adopted.
