Even in harsh environments

First-class, integrated network solutions

The highest level of safety, availability, capacity and regulatory compliance – sustainable rail communications systems demand nothing less. Applications range from comprehensive passenger information and infotainment services for increased customer satisfaction to efficient traffic management. But that's not all: Siemens enables secure wireless data transmission between track and train - even over long distances. This simplifies the data management, ensures passenger safety and simplifies operational procedures.

Keeping passengers informed, maintaining safety onboard, managing and monitoring vehicle controls – all of these complex and critical functions require a robust network to keep information flowing. Railway operators face a unique challenge of maintaining a real-time awareness of what’s going on inside the train and of any factors that impact train operation.

 

In many cases today, networks for passenger information systems, vehicle control and management systems are maintained separately. With Siemens, these networks can be seamlessly integrated to share information, and to provide operators with a complete picture. Siemens’ comprehensive network solutions provide rail operators an opportunity to embrace network convergence and unify important streams of data to achieve greater operational efficiencies.

 

With a Siemens onboard Ethernet network, the possibilities are virtually endless, from services for passenger information to mission-critical operational data. Rail operators can also rest easy, knowing that Siemens products seamlessly integrate with legacy devices, allowing operators to leverage their existing network investments.
