Introduction
Darren Kettle, CEO of Metrolink, discussed the agency’s transformation and award-winning innovations, including the Student Adventure Pass, Wireless Crossing Nearside Station Stop technology, and Earthquake Early Warning System, in an interview following the 2025 Railway Technology Excellence Awards.
Awards and Vision
The 2025 Railway Technology Excellence Awards recognize Metrolink’s commitment to innovation, safety, and equity. According to CEO Darren Kettle, the awards validate Metrolink’s evolution from a commuter rail system to a regional rail provider. This transformation, referred to as “Metrolink Reimagined,” aims to reshape mobility in Southern California. Key projects highlighted include the Student Adventure Pass, the Wireless Crossing Nearside Station Stop technology, and the Earthquake Early Warning System, all aimed at enhancing safety, reliability, and accessibility. A major fare restructure is also underway to simplify the pricing system and promote equity for riders.
Innovation and Technology
Metrolink’s culture of innovation is driven by a willingness to adapt and challenge traditional industry practices. The agency encourages its teams to explore new ideas in areas such as zero-emission trains, real-time alerts, and safety technology. The Wireless Crossing Nearside Station Stop (WCNSS) technology’s scalability depends on funding. Beyond crossings, AI and digital platforms offer potential for improving the customer journey, including personalized trip planning and self-service modules. Technology also plays a role in managing operations more efficiently and reducing costs.
Earthquake Early Warning System
The integration of USGS ShakeAlert technology into Metrolink’s Earthquake Early Warning system was a significant advancement. In April, a 5.2-magnitude earthquake near Julian, California, triggered the system, causing trains to automatically stop. This event served as a real-world test of the system, demonstrating its effectiveness in ensuring passenger safety. Partnerships with organizations like Caltrans, the USGS, and local entities are crucial for innovation. Metrolink incorporates feedback from riders, including students, through surveys, community meetings, and digital tools to improve service and product offerings.
Future Initiatives and Challenges
The momentum towards zero-emissions trains is a key area of focus for Metrolink. The Zero Emissions Multiple Unit (ZEMU) pilot, launched on the Arrow service in mid-September, represents a significant step in transitioning away from fossil fuels. Open payments and digital tools are also expected to make transit more accessible. Funding and governance remain significant challenges, particularly given that Metrolink serves six counties with multiple partners.
