Phil Nguyen shares his global insights on building high speed rail in Australia
At a glance
With more than 27 years of global rail experience, Phuoc ‘Phil’ Nguyen shares lessons for Australia’s high speed rail future, drawing on senior planning and delivery roles in the United States, to help build community trust, long term value and outcomes grounded in local context.A career shaped by rail
Rail has been a consistent theme throughout Phil’s career. He traces his engineering pathway to growing up in Vietnam in a family with deep roots in contracting and construction. He saw how infrastructure can support communities, livelihoods.
Phil began his professional journey as a roadway and highway designer, including roles with FHWA and Caltrans, developing strong digital design foundations before moving into freight rail. That shift opened opportunities across rail project engineering, design management and technical leadership, eventually leading to work on one of North America’s most significant high speed rail programmes.
“Rail is still a relatively niche discipline in some markets,” Phil says.
“Many people move across from roads or civil design and bring skills that transfer well. What keeps people in rail is the scale of the work and its long-term impact.
You’re contributing to infrastructure that will serve communities for decades.”
Experience across the project lifecycle
A defining chapter of Phil’s career was his involvement in the California High Speed Rail Program supporting the San Francisco to Central Valley section through planning and design. As Engineering Design Manager, he worked with multidisciplinary teams on environmental approvals, alignment development and public engagement.
During planning, teams assessed a wide range of potential route options, balancing engineering requirements with environmental constraints and community feedback. Phil emphasises that technical decisions and community outcomes remain closely linked.
“Alignment decisions are never just technical,” he explains. “People want to understand how projects affect their land, access and daily lives. Early listening and clear communication can make a real difference.”
Phil later served as Engineer of Record for track design during the final track and overhead contact system package. His end-to-end involvement from early planning through to detailed design continues to shape how he approaches complex rail programmes.
Technology supports outcomes, not the other way around
Rail systems have evolved rapidly in the past two decades, particularly in signalling, communications and asset management. Phil has seen a shift from manual inspections and spreadsheet based processes to digital platforms that support real-time monitoring and safer operations.
In the United States, systems such as Positive Train Control use GPS based technology to track train movements and manage operational risk. Other markets have adopted communications-based train control to increase service frequency and operational flexibility.
“Technology is an enabler, but public confidence is built through visible everyday outcomes, service reliability, clarity and consistency.”
Lessons for Australia’s high speed rail future
As Australia continues to explore high speed rail options between major cities, Phil sees three key lessons from international projects that can inform local decision making, especially as megaprojects such as high speed rail is introduced.
Start with corridor readiness and clear accountabilities
Phil’s CaHSR experience highlights the risk of advancing construction before right-of-way, utilities, third-party agreements, and clearances are substantially secured, and the compounding delivery impacts when design and interface ownership is fragmented across packages.
Be honest about the critical path
Environmental approvals and third-party coordination often drive the real timeline, requiring long-run resourcing, clear governance and risk-adjusted commitments that match engineering realities.
Match capability to phase and maintain continuity
Planning and environmental pathways require different leadership and skills to detailed design and delivery. Maintaining continuity across phases helps retain intent, reduce avoidable rework and maintain a clear line-of-sight from business case to buildability.
Building rail that serves people and place
High speed rail is not only about speed. It shapes cities, connects regions and influences how people experience place and movement. Phil’s experience across planning, design and delivery highlights the value of learning from global programs while responding carefully to local needs.
By focusing on people, place and transparency alongside sound engineering, we can support clients as they navigate the complexities of high speed rail and make informed decisions about the networks they want to create.
