Trains on the line operated via Fitzroy and the Inner Circle, until the opening of the current connection between Victoria Park and Princes Bridge stations in 1901. Passenger services were operated in two tiers: a local train to Preston Reservoir station via Clifton Hill, and a country mixed train to Whittlesea, via Fitzroy. The Epping line was electrified to Reservoir in 1921, with an AEC railmotor providing a shuttle service between Reservoir and the terminus at Whittlesea. Preston Reservoir station was renamed Reservoir in 1909.
