of the Bayside Rail Upgrade, stations on the Frankston line will receive new "network status boards". These LCD screens provide travel information on all of Melbournes 16 railway lines as well as tram & bus services, including delays, replacement services or planned disruptions. Safeworking Most lines in Melbourne operate under an automatic block system of safeworking with three-position power signalling. This permits signals to operate automatically with the passage of trains, enforcing the distance between them. At junctions signals are manually controlled from signal boxes, with interlockings used to ensure conflicting paths are not set. The Flemington Racecourse line has two-position automatic signalling, a variant of the three-position system. The outer end of the Hurstbridge line used to be operated with token based systems and two-position manual signalling, where access to the line is based upon possession of a token. It was dismantled in 2013. Train stops are used to enforce stop indications on signals—should a train pass a signal, the train's brakes will automatically be applied. Trains are also fitted with pilot valves, a form of dead man's switch that applies the brakes should the driver fail to maintain a foot or hand pilot valve in a set position. The "VICERS" vigilance control and event recorder system is also being currently fitted to suburban trains to provide an additional level of safety. Train control The main control room for the rail network is Metrol. Located in the Melbourne CBD, it controls signals in the inner suburbs, tracking the location of all trains, as well as the handling the distribution of real time passenger information, and manages disruptions to the timetable. Additional signal boxes are located throughout the network, and in direct communication with Metrol. Terminology The railways in Melbourne generally use British-derived terminology. For example: Up refers to the direction "towards Melbourne". Down refers to the direction "away from Melbourne", or "towards the country". Points refers to what are known as railroad switches, or crossovers in American English. Signal box refers to the signal control installation (tower in American terminology).

Australia's financial years start on 1 July and end on 30 June. Major events that affected the number of journeys made or how patronage is measured are included as notes.
