[1] Several unscheduled calling points existed on the section between Slaggyford and Lambley, including Whitwham, Softley, and Burnstones.

[2] Trains regularly stopped to allow passengers to board and alight, despite the lack of platforms or facilities at these locations.

[5] It was later decided that extending the line only to Alston would be sufficient, and the revised route was approved by a second Act of Parliament in July 1849.

The construction of the branch line was completed in November 1852, following the opening of the, now Grade II* listed,[6] Lambley Viaduct over the River South Tyne.

Following improvements to the road network, including a temporary level crossing over the branch at Lambley, the line was closed on 3 May 1976 by the British Railways Board, with the last train working two days earlier.
