"New Trains for the Bakerloo Line - Boris claims responsibility"

Link to 'nycsubway.org'

"The Baker Street & Waterloo Railway belongs to the London Electric Railway and, for brevity, is commonly referred to as the 'Bakerloo'. This is an underground tunnel line some 6 miles long running from the Elephant and Castle in South London to a junction with the London & Northwestern Railway at Queen's Park, Willesden, in the northwest of London.

"Some little distance before reaching the tracks of the London & Northwestern Railway the tube line comes to the surface. This extension and the making of a physical connection with the London & Northwestern line were completed two or three years ago, when the newly electrified tracks of the Northwestern company were finished.

"The electrified tracks of this latter company run out into the country as far as Watford, and the distance which the through electric trains will run from the Elephant and Castle to Watford is twenty-one miles. Direct current at 600 volts, with third and fourth-rail conductors, is employed.

"When these new cars were ordered in 1914 it was realized that additional rolling stock would be necessary in order to meet the growing requirements, but owing to delay caused by the war these cars are only now being delivered."
