 The high tractive effort of the C class locomotives enabled Victorian Railways to operate heavier goods trains with a single locomotive and thus enabled significant savings in operating costs through a reduction in train-miles for the tonnage hauled.Along with the smaller K class branch line 2-8-0, they were credited with playing a major part in the 15% reduction in overall goods and livestock train miles on Victoria Railways between 1920 and 1924, against a reduction of overall tonnage hauled of only 3% for the same years.Upon introduction, locomotive C 1 was put to work operating through goods trains on the Melbourne to Seymour line.
