Passenger trains in the early years used lightweight KA Tramcars which were specially built for the line, but were also used at Yass and Carlingford.

The main source of income for the line was the coal loader at Narellan and the Dairy Farmers Milk Co-operative depot at Camden.

[2] Traces of the original line's route can still be seen along looking up Kirkham Lane from Camden Valley Way, including a wooden bridge along this section towards Narellan.

[1] Every year, on Good Friday, three or four special trains were run from Sydney to Maryfields, to cater for public attendance to the Via Crucis religious ceremony held on the grounds of the Franciscan Brothers monastery near Campbelltown.

[3] This required out-of-the-ordinary working over the branch line, which also included the provision of an additional locomotive at both the front and rear of each train.
