In 1907 a branch line was opened by the GWR from Denham to Uxbridge; the work cost £87,459. The trains ran from Gerrards Cross, starting on 24 April; goods traffic started on 11 May 1914. The line was originally intended to connect through to the Vine Street station, terminus of the earlier Uxbridge branch from West Drayton. Although some land for the connection was acquired, the through section was never built, and the branch remained a dead end; it as two miles in length and double track until 1922, when it as reduced to single line.
