A new through branch via Creekmoor opened to a new Poole railway station in 1872 which meant that passengers had a direct service to the town, and following the opening of the causeway across Holes Bay in 1893 allowing through trains to serve Poole, the Hamworthy Branch lost its passenger status in 1896.

[2] The line was once worked, as part of the local pick up goods rounds, by a Southern Railway B4 class 0-4-0 steam locomotive.

During the late 1960s and early 1970s the line was worked by Class 03 Drewry 0-6-0 diesel shunting locomotives numbers 03 179 and 03 083, occasionally as double headers (cab to cab) when hauling a long train of Ford transit vans on bogie flat wagons or heavy girder and sheet steel rolls on bogie bolsters.

The brake vans used were the standard BR type, occasionally carrying a bicycle on the rear platform, as the train would stop at the hand opened level crossing gates in Ashmore Avenue, a man would jump down from the locomotive, open the gates and the train would proceed through.

[3] The branch remained connected to the mainline network for many years, but has since been cut off by the partial removal of the points at Hamworthy.
