This paper is a continuation of that made to the IRSE in Adelaide on 14 March 2003 by Tony Simes and Alistair Morrison. In that paper we reviewed the existing TransAdelaide (TA) rail signalling system with a particular emphasis on the CTC system. We then looked at the need for replacement of the current CTC system, examined the review, tendering and evaluation processes leading to the awarding of a contract to ALSTOM Australia Pty Ltd and finally looked at the ALSTOM bid and the systems that are to be replaced. In this paper we will briefly revisit the need for replacement of the CTC system and then focus on what has transpired between 14 March 2003 and 29 October 2004. We will also look at some safety related issues that have occurred locally and examine how these have influenced the project with an emphasis on strategies aimed at improving TransAdelaide's safety performance.
ALSTOM will then provide a project status report; with a particular focus on ARS, alarms, fault management and pseudo interlocking and outline features to be delivered. The paper will finally examine strategies leading to the eventual commissioning of the new CTC system and how this will be achieved while simultaneously "Mitigating the Risk" and any system downtime.
