In May 2007, the Tranzinfo network began using an automated interlibrary loan system, with the software and maintenance provided through Prosentient Systems.

This system replaces the Union List of member periodical collections and allows for both a dynamic database of holdings and automation of article interlilbrary loan requests. While currently only incorporating periodical holdings, collection information for runs of conference proceedings is a planned addition in late 2007.

The libraries involved in the establishment of the system were:

Australia

• ARRB Group - MG Lay Library 
• Australia Department of Transport and Regional Services Library
• Centre for Automotive Safety Research (CASR) 
• Infralib, Victorian Department of Infrastructure
• Main Roads Western Australia
• Port of Brisbane Corporation
• Queensland Department of Transport and Main Roads Library
• RACV Business Research Library (since closed)
• Roads and Traffic Authority (NSW)
• SMEC
• South Australia Department for Transport, Energy and Infrastructure Library 
• Tasmania Department of Infrastructure, Energy and Resources
