in 1939 and work only recommenced in 1945. This involved the construction of a new tube tunnel from Leytonstone via Redbridge which surfaced at Newbury Park to connect with the lines of the existing Ilford to Woodford branch. During the war, a part of the constructed tunnel system was used as an underground aircraft munitions factory, and was used as an air raid shelter. Steam train services serving Newbury Park were permanently suspended after 29 November 1947. Electrified Central line passenger services to Central London via Gants Hill finally commenced on 14 December 1947. Lord Ashfield, former chairman of the London Passenger Transport Board, and local dignitaries attended the opening ceremony of the extension. A train crew depot was established on 30 November 1947 but closed on 2 November 1953. In addition, the line beyond, to the new Hainault depot, was electrified for empty train movements. The station ceased to be the temporary terminus of the Central line on 31 May 1948 with passenger services to Hainault station reopened. The surface tracks from Newbury Park to Ilford were severed by the expansion of Ilford Carriage Sheds in 1947, whilst those to Seven Kings were severed in 1956. The former alignment was in a cutting which was filled in and subsequently provided land for allotment gardens and housing. Three road bridges (Vicarage Lane, Benton Road and Wards Road) spanning an apparently missing alignment are the only clues to the old railway. Goods services used to run from the station via Woodford to Temple Mills, reversed via a turn-back siding south of the station until 1965, and by Underground engineering trains until 1992 when it was finally abandoned. An unelectrified track existed next to the 9 sidings which was a reception track to Barkingside goods yard. With the freight yard closed on 4 October 1965, these were demolished on 12 October 1969. North of the station, the tracks were rearranged upon transfer to London Underground such that the existing tracks were separated further apart, where the former through eastbound track became a reversing siding, though retaining the connection towards Barkingside, whilst through trains use a track formerly part of the sidings and freight yard built to the west of the running lines. The northern end of the platforms were truncated to facilitate insertion of the points-work for the re-arrangement. Nine stabling sidings were added to the northwest of the station, connected to
