 Quainton Road remained open, but with the closure of the Brill Tramway it was no longer a significant junction. A connection between the GCR and the former Buckinghamshire Railway at Calvert was opened in 1942, leaving the A & B route to Verney Junction with no purpose other than as a diversionary route. It was closed to passengers on 6 July 1936. London Transport passenger services beyond Aylesbury were withdrawn, leaving the former GCR (part of the London and North Eastern Railway after 1923) as the only passenger services to Quainton Road.
