Queensland Rail (QR) chief information officer Patrick Lilwall left the organisation this month after just over a year in its top technology role.
"After 12 months as general manager information services, Patrick Lilwall left QR in March to pursue other opportunities," the organisation's group general manager shared services Martin Moore said in a statement.
Previously an account director at local IT services firm SMS Management & Technology for four and a half years, Lilwall took the Queensland Rail spot in January 2009 following the departure of the group's long-standing CIO Dallas Stower.
Queensland Rail is currently engaged in a long-running project to transform its internal enterprise applications with the aid of German giant SAP and HCL-Axon. The organisation has a sizable internal technology division.
"QR's information technology transformation remains a high priority. However, the imminent separation of Queensland Rail from QR and the subsequent initial public offering of QRNational is taking precedence in our planning. The complexity and scale of this task is significant," Moore said.
The organisation had appointed an acting general manager Information Services Division role, Malcolm Sturges-Britton, who would be guiding the next stage of transition planning, the organisation said. Sturges-Britton has worked for QR since 2009 in a senior IT role.
