 The line was single track and worked from the start by the Great Western Railway, which provided a service of three trains each way daily.The A&BR, which had for some time been in a parlous financial state, was absorbed by the Metropolitan Railway with effect from 1 July 1891.From 2 April 1906, all Metropolitan services north of Harrow South Junction to Verney Junction were run by the Metropolitan and Great Central Joint Railway; this continued until 6 July 1936 when the London Passenger Transport Board, which had taken over the Metropolitan in 1933, withdrew local passenger services as an economy measure.
