Optima M1 Rugged Cabinets for Railway Installations

 Press Releases

  • Technical Highlights                                                                  

    • EN 51055-compliant for secure railway communications
    • Powerful Cisco Advanced Enterprise IOS and Mobile Ready Net capabilities
    • Rugged construction designed to endure rolling stock and mobile applications

    FREMONT, California – Elma Electronic Inc. now offers a fully EN 51055-compliant NetSys-5304 that facilitates seamless, secure communication in rolling-stock applications that involve vehicle positioning, monitoring, speed control and collision avoidance.  The NetSys-5304 is part of Elma’s Cisco-enabled family of rugged systems designed for high performance communication and computing at the network edge.

    Designed to deliver secure IP-based data to mobile rail and transportation applications, the NetSys-5304 is based on Cisco’s 5915 Embedded Services Router (ESR) with Advanced Enterprise IOS and Mobile Ready Net capabilities.  An on-board hardware encryption engine ensures secure, uninterrupted handling of all data, video and voice. 

    Layer 3 routing protocols quickly and seamlessly establish ad hoc networks as nodes shift relative to positioning in and out of the range of fixed networks. 

    The NetSys-5304 also includes radio aware routing, quality of service (QoS) support and a dynamic link exchange protocol. These routing optimization protocols ensure sufficient bandwidth to critical wireless nodes in the time and sequence necessary to support network communication requirements.

    Ram Rajan, senior vice president of engineering at Elma Electronic, noted, “By combining our engineering resources with our packaging design skills, we were able to deliver both the performance and reliability needed for secure communications in today’s rugged railway applications. To meet the EN 51055 standard, our NetSys product needed to demonstrate high degrees of fault protection, built-in diagnostics and easy maintenance.”

    The NetSys-5304 features a fanless design that provides passive conduction-cooling and reduces maintenance needs as well as possible component failures.  The robust M12 connectors and an IP67 rating ensure that the system can withstand severe environmental conditions, such as intense shock, vibration and humidity typically found in rugged, mobile applications.

    The unit comes equipped with front LEDs to quickly verify system status as well as link activity. 

    Pricing for the NetSys-5304 is dependent on configuration.

  • Optima’s M1 Rugged Cabinet Desiged to Meet AREMA & CENELEC Standards

    For use harsh Railway and Transportation Environments

    Starting with a standard M1 design, Optima provides cabinet designs tailored to specific uses, both on-board and trackside.

    Optima has the expertise and capability to modify its standard M1 cabinet design and test it to a customer’s environmental requirements, ensuring that the designs meet or surpass those tests before shipment, resulting in significant

    time savings for the customer. Below follows a design example for a project that required meeting both AREMA and CENELEC testing requirements. Short videos of each test can be found here: https://fast.wistia.net/embed/channel/ijrk4881ym

    Customer Requirements

    Provide complete, tested cabinet platforms in different sizes to house rackmount equipment located on-board railway locomotive trains intended for public transportation and off-board applications like signal control rooms and cable management. Control room and wayside racks had to be shielded to meet IP42, IP 54 and applicable IEC standards. All cabinets also had to meet earthquake requirements as well as AREMA and CENELEC standardized tests for shock and vibration.

    Optima Solution

    Optima stepped up to the challenge using the standard M1 welded aluminum cabinet series as the base for the customer’s design. Our engineering team designed several rugged cabinets to meet the specs. The cabinets were then test to meet the various requirements before shipping to the customer, saving them valuable time in the process of both design and testing. The cabinets were tested to AREMA C&S Manual, Part 11.5.1 (Recommended Environmental Requirements for Electrical and Electronic Railroad Signal System Equipment), Section D.4 (Vibration) and D.5 (Shock), Class I)) and CENELEC rail specification standards for shock and vibration (EN 61373:2010). The vibration was an especially severe endurance test.

    Overall Benefits

    What made the solution unique is that it was able to pass the testing without the assistance of shock and vibration damping (isolators) typically needed for this type of cabinet construction. The cus­tomer was very satisfied and Optima is now positioned to provide racks that will protect sensitive, on-board and wayside rail applications worldwide.

  • The high strength-to-weight ratio design of the Optima M-Series cabinet supports and protects critical railway equipment during the full force of a seismic or other shock/vibration event.

    Optima M1 cabinets are designed and successfully tested to meet both North American (AREMA) and European (CENELEC) railway standards. The cabinet is designed to pass all testing to qualify for use in railway applications, where high vibration and shock conditions occur.

    The welded and riveted frame is designed by modifying Optima’s standard M1 cabinet frame design. In one design challenge, it needed to meet a customer’s specific requirements for AREMA Part 11.5.1 Class I – Vehicle Interior (Platform-Mounted), which examines the operation of electronics inside locomotive spaces. Optima’s cabinet did not require shock isolators in order to meet the mechanical shock and vibration requirements mandated by the railway industry.
