The following year, on 20 November 1905 the whole line between Greenford and Grendon Underwood was opened for goods trains. At the same time the Neasden to Northolt GCR section was opened. On 1 March 1906 the latter section was opened for passenger trains in the form of railmotors. The first miles from Neasden were quadruple track; the remainder was double line. There were stations at Wembley Hill (on the four track section) and at Sudbury & Harrow Road railway station and at South Harrow; at the latter two places passenger loops were provided for the platforms, with the through lines in the centre.
