(Estimates Committee A) The Hon. S.C. MULLIGHAN House of Assembly Lee Minister for Transport and Infrastructure Minister Assisting the Minister for Planning Minister Assisting the Minister for Housing and Urban Development Rail Signalling System The Hon. S.C. MULLIGHAN (Lee—Minister for Transport and Infrastructure, Minister Assisting the Minister for Planning, Minister Assisting the Minister for Housing and Urban Development): I have been advised of the following: 1.	Prior to July 2014, only a sample of train trips were audited for on-time running performance each quarter. From July 2014, all train trips have been recorded for on-time running through the signalling system. The time point used to record train arrival at the Adelaide Railway Station is the first signalling circuit on the platform at which the train is arriving, not when entering the Adelaide rail yard. 2.	There are currently two signalling systems in use on the Adelaide network. 3.	Testing and commissioning of the Automatic Train Protection (ATP) System has been completed, with the system expected to come into operation on the Seaford and Tonsley lines in the final quarter of 2015. All electric trains are expected to be operating with ATP by early 2016. It is expected that diesel trains will be operating with ATP by the second half of 2016. 4.	The current project provides for the ATP system on the Seaford, Tonsley and Belair Lines. 5.	The SigView train control system provides the express or stopping status of each train automatically to the signalling system based on the operating train timetable.
