Editing London Underground (section)

==== Electrification ====
With the advent of electric Tube services (the Waterloo and City Railway and the Great Northern and City Railway), the [[Volk's Electric Railway|Volks Electric Railway]], in [[Brighton]], and competition from electric trams, the pioneering Underground companies needed modernising.<ref name=":5">{{Cite book|title=The London Underground|last=Emmerson|first=Andrew|publisher=Shire Publications Ltd.|year=2010|isbn=978-0-74780-790-2|location=London}}</ref>  In the early 20th century, the District and Metropolitan railways needed to electrify and a joint committee recommended an [[Alternating current|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 [[Direct current|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.{{sfnp|Day|Reed|2010|pp=62–63}}
