Communications and Information Systems are essential components of the railway system. The communications networks are used to carry mission-critical voice and data services for time-sensitive applications across optical, fixed, mobile and wireless networks.
Local access networks provide data services for information, security and automated station systems that support and enhance the overall passenger journey experience. SNC-Lavalin has direct experience in the specification, engineering, delivery, integration and migration into operational service of these technologies in mainline rail and metro environments.
The trends in communication and information system technologies has shifted towards feature rich commercially off the shelf (COTS) software driven server solutions networked together using Ethernet services across a next generation Internet Protocol (IP) infrastructure.
Station and information systems have seen a move towards standardized open data interfaces utilizing centralized data storage and management techniques aligned with Big Data thinking.
Railway train and electrification control systems are migrating from their traditional trackside environments to reside in centralized control center locations and/or on the train increasing the dependency on robust and resilient communications infrastructure and the role of the system integrator. SNC-Lavalin offers that industry-leading expertise in signaling, control centers, rolling stock and communications.
Our broad experience enables us to develop technology strategies, system road maps and migration paths that are able to be implemented upon existing railways with minimum service disruption.
