HOW IT WORKS
Our Approach to Sentinel Transit Barriers
The Sentinel Transit Barrier system is specifically designed to prevent accidental falls and guide visually impaired passengers at transit platforms. Installed between rail cars, these barriers create a clear, physical boundary that helps passengers safely navigate busy transit environments.
The Federal Americans with Disabilities Act (ADA) and the Federal Transit Administration (FTA) require transit agencies to take steps to ensure the visually impaired patrons do not fall from the elevated platform to the trackway below in the space between the train’s coupled vehicles.
Sentinel is the only platform-mounted between-car barrier system that meets the provisions placed by the Federal Transit Administration (FTA).
Sentinel is a platform-mounted between-car barrier system designed for rail transportation systems with elevated platforms and level boarding conditions. It provides safety protection in the gap between coupled train vehicles to prevent passengers from falling to the trackway below.
Sentinel is the only platform-mounted between-car barrier system that meets the provisions placed by the Federal Transit Administration (FTA). It features a patented reactive spring system that allows the barriers to be traversable while maintaining their protective function.
Yes, Sentinel is fully ADA compliant with a 1-inch tail height that was specifically developed to minimize hazards. The system helps transit agencies comply with the Federal Americans with Disabilities Act (ADA) and Federal Transit Administration (FTA) requirements.[1]
The system helps transit agencies meet their obligation to prevent visually impaired patrons from falling from elevated platforms to the trackway below in the space between coupled train vehicles, as required by both the ADA and FTA.
Sentinel has undergone accelerated weathering testing according to ASTM G26 2500kl standards, maintaining a minimum gloss retention level of 60% after 4 years of weathering exposure.
Yes, Sentinel meets the UL94 V-0 Fire Rating Standard for flammability performance.
The system provides Delta E measurements of 2 for chemical resistance, ensuring durability against various chemical exposures.
Yes, Sentinel features a modular design that allows for easy customization of rail lengths and post heights to meet situational and local legislative requirements.
Sentinel requires only 3 anchors per rail, which addresses electrical conductivity concerns within the platform and minimizes installation complexity.
Yes, uprights are available with retro-reflective sheeting to improve visibility.
Sentinel posts are designed to be traversable, allowing wheelchairs, motorized carts, or maintenance vehicles to roll over them during emergencies or train docking errors. The internal spring mechanism automatically returns the post to its original upright position afterward.
Each Sentinel upright contains a patented compression spring assembly concealed within the post that provides optimal strength to support the flexible uprights while maintaining traversability. This system ensures uninterrupted, lasting protection.
Yes, all hardware except the anchors is tamper-resistant, helping protect against theft and unauthorized removal.
Sentinel is ideal for rail transportation systems that have elevated platforms and level boarding conditions with consistent rail car length.
Yes, Sentinel has undergone various standardized tests including UL94 V-0 fire rating, ASTM G26 weathering tests, and meets Federal Transit Administration (FTA) provisions.
