In order to provide a service to the nearby Inglis Barracks, works continued between Finchley Central and Mill Hill East.

[16] The planned second platform at Mill Hill East was not built and the service continued to operate over the single track line as before.

Maintenance works and reconstruction of war damage on the existing network had the greatest call on London Underground funds.

Funds for new works were severely limited and priority was given to the completion of the western and eastern extensions of the Central line to West Ruislip, Ongar and Hainault.

[23][n 4] British Railways (the successor to the LNER) freight trains continued to serve the station's goods yard until 1 October 1962, when it was closed.

As one of two EH&LR stations retaining their original buildings (with Finchley Central), it is one of the oldest parts of the Underground system, pre-dating the first tunnelled section of the Northern line (the City and South London Railway) by more than twenty years.

[27] The works included structural repairs to the station and platforms, the re-decoration and re-tiling of walls and floors, a new public address system,[27] as well as CCTV cameras and Help Points.

[27] The station was made accessible in 2020 by means of a new lift and link bridge, which was prefabricated off site, and craned into position in August 2019.
