Electrification of important suburban tracks in the London area—notably on Liverpool Street and King's Cross routes of the London and North Eastern line, and the Great Western North Acton-Ruislip section—is likely to be undertaken in the near future. These new works follow the decision of the Government to assist in the improvement of transport facilities in the London district by a guarantee of the necessary loans. The programme involves the electrification of approximately 44 miles of suburban railway, the doubling and electrification of about 12 1/2 miles of further suburban lines, and the building of about 12 miles of new tube railways. The total cost of the works is in the region of £35,000,000, and it is estimated that the improvements will be completed within a period of five years from their commencement.

Electrification of the Liverpool Street and King's Cross suburban routes will come as an immense boon to the traveller. It is proposed to electrify throughout, the Great Eastern suburban line from Liverpool Street to Shenfield, and the Loughton Branch and Fairlop loop. The Central London tube line will be extended from Liverpool Street eastwards to connect with the Loughton Branch and Fairlop loop lines, and through trains will be operated. On the Great Northern section of the L. and N.E. Railway, out of King's Cross Station, it is proposed to electrify the Edgware, High Barnet and Alexandra Palace lines, to extend the Highgate tube to make a connection with these electrified suburban lines at East Finchley; and to extend the Northern City tube line, which now terminates at Finsbury Park, to make a connection with the electrified suburban lines near Finsbury Park. Through train services will be operated from all branches to the City, and from the Edgware and High Barnet lines to the Central Area. An interchange station will be provided at Highgate for passengers from the Alexandra Palace Branch to the Central Area. Outside Paddington, the proposal is to construct and electrify two additional tracks from North Acton to Ruislip, on the Great Western Railway. The Central London tube trains, now terminating at Wood Lane, will be extended to operate over this line so as to provide direct services to the Central Area and the City in place of Paddington.
