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.
