Caulfield to Dandenong Level Crossing Removal Project
Acmena’s systems engineering and assurance expertise plays a critical role in delivering Melbourne’s benchmark level crossing removal project.
Challenge
One of the most significant challenges was obtaining ONRSR approval for the use of a straddle carrier. Not only had the technology never been used before in Australia, gaining approval for its use in daytime over a live railway was vital to constructing elevated sections of rail in a narrow residential corridor, and ensuring the project was completed on time with minimal disruptions to the network.

Approach
Acmena used Goal Structuring Notation (GSN) to develop and demonstrate safety cases. This enabled our team to simplify complexity and engage more effectively with stakeholders, including ONRSR. The use of IBM DOORS Next fostered greater visibility and collaboration across the project while allowing Acmena to provide evidence-based reports to demonstrate compliance with safety and regulatory requirements.
Outcome
Acmena’s approach was critical to obtaining approval for the use of the straddle carrier and ensuring the project was completed on time, on budget and with minimal disruptions. Our pragmatic approach was adopted by LXRA and subsequently employed to create efficiencies on other level crossing removal projects, with LXRA staff being up-skilled in the process.
