Kickstarting success in communications-based train control: Four key steps
Communications-based train control (CBTC) is changing the game for transit, making it faster, safer and more reliable by replacing legacy train control technologies with cutting-edge wireless technology. This new connectivity allows for constant communications between trains as well as the control center that manages train movement. Although installing CBTC is complex, there are smart steps agencies can take to prepare, improving their transit systems even before CBTC is up and running. Here are four ways to set the stage for CBTC success.
Where it all begins
Identifying and securing funding is the first step in planning for CBTC development. Transportation agencies often must juggle competing priorities within their capital programs, departmental budgets and timelines. To tackle this, agency leaders need to set clear priorities and align their train control migration with overall capital improvement plans. With funding usually tight, exploring federal, state and local grants can be a crucial part of project development. By identifying these resources early, agencies can map out a realistic project scope and create a phased plan for rolling out the CBTC system.
Partnering for success
By engaging with a trusted partner, agencies can advance a smoother, safer and more cost-effective CBTC transition while building a solid foundation for long-term operational success. Experienced partners bring specialized expertise in key areas such as technology, design, alternative delivery and implementation strategies, risk mitigation, cost reduction and knowledge transfer. Their know-how and deep understanding help them spot potential challenges early on, resolve issues quickly and avoid design or implementation mistakes — saving agencies time and money.
Working with the right team can set agencies up for long-term success. By focusing on the future, they can help train agency staff, provide clear and comprehensive documentation and create scalable systems easing maintenance and allowing for seamless expansion down the road. Further, a partner that understands agency procedures, departments and business processes can help tailor procurement and roll-out strategies to meet agency needs. Our AECOM team provides these insights for the Maryland Transit Administration (MTA) as the agency introduces a new CBTC system for the Baltimore Metro. As the project’s program and construction manager we serve as MTA’s trusted advisor, collaborating with the agency and applying our technical expertise and agency knowledge to guide the contractor to optimal solutions that will meet MTA’s needs. This teamwork is streamlining and reducing the new system’s costs.
Plan the rollout
CBTC offers many benefits — like cutting down on system maintenance — but it’s no secret that development and installation is challenging, particularly when it is overlayed onto an existing system. For agencies with tight budgets, breaking the project into phases, such as assessment and planning, design and integration, and pilot demonstrations can keep it moving forward.
Building a solid phased approach is often a juggling act. To create an effective plan, agencies need a clear understanding of their current system — its strengths, needs, available funding and resources. This all must be weighed against CBTC components and installation capabilities to establish the rollout timeline and how to tackle it. Whether it’s a short- or long-term project, the goal should be to complete each phase thoroughly, build on progress and get the system ready for full CBTC installation.
Improve the current system
Introducing CBTC components incrementally is often the most practical means of installation. This allows transit agencies to lay the groundwork for full system deployment while improving existing transit infrastructure.
Fiber optic networks, for example, serve as the backbone of CBTC and represent an excellent starting point for development. Building out and integrating these networks enhances older transit systems by enabling critical functions such as station-to-station communication, live CCTV monitoring for security, and real-time public service announcements. These capabilities prepare the system for CBTC migration while providing immediate benefits, including improved safety and communication. Real-time wayfinding and emergency incident management information can assist passengers during disruptions. To ensure a smooth transition, agencies might consider issuing requests for information to the industry to confirm that communication infrastructure installed in advance will fully support future CBTC signaling migration.
The path forward
Transitioning to CBTC is a journey, not a leap. By securing funding, collaborating with experienced professionals, planning phased rollouts, and enhancing existing infrastructure, transit agencies can build a foundation for safer, faster and more reliable service. Incremental improvements today pave the way for tomorrow’s CBTC systems, delivering immediate benefits while setting the stage for long-term success.
