House of Assembly Fifty-Third Parliament, Second Session (53-2) 53 2 Parliament of South Australia House of Assembly published Question Time Rail Signal Failures Rail Signal Failures Mr WINGARD House of Assembly Mitchell Rail Signal Failures Mr WINGARD (Mitchell) (14:28): Given that half a billion dollars was spent on the rail revitalisation program, why did the government feel that signalling issues were not a key component of that as a safety factor to keep public transport users safe? 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 Signal Failures 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) (14:28): The content of the answer from the previous question would go some way to answering this current question. As I said, we are part way through a significant upgrade program of our rail network, and while some parts of the network have been improved, there are other parts of the network which have not yet been improved. Providing this additional money means that we can minimise the risk and chances of these sorts of service interruptions from occurring in the future.
