Industry leader in confined space communications, incorporating technologies such as radiating coax (leaky feeder). Tunnels, mountains, canyons. No matter the rail line, Tunnel Radio signals come through loud and clear.
Unbroken simplex or duplex operation through the longest tunnels and most remote passes. All within the AAR 160 MHz band. Plus, Tunnel Voice is compatible with digital narrow band.
Extend the 220 MHz signal through any length of tunnel or mountain pass, meaning you never lose sight — or control — of your trains.
Our network of amplifiers and distributed antenna cable extends the distributed power and end-of-train/head-of-train radio signals, keeping your systems connected from portal to portal.
TRCentral makes data on system performance, troubleshooting, and other information easily accessible through local networks or online remotely.
OFA connects to existing base sites wirelessly, with adjustable frequencies. It’s compatible with Tunnel Link and Tunnel Voice, and it can run on solar power if a wired power source is unavailable.
Control communications from anywhere via web-based software.
Our support team is ready to help. Any day, any hour. Onsite, by phone or online. It’s that simple.
Downtime equals money lost. We’ll fast-track your project from Day One.
Advanced wireless technology improves read, reliability and versatility in underground operations.
Built to perform — everywhere
Tunnel Link railroad technology for distributed power and positive control is the industry leader. Built to last in harsh and remote environments, Tunnel Link™ and Tunnel Voice™ mobile radio systems are performance-proven in even the longest, deepest railroad tunnels.
No dead spots
The Tunnel Link™ data system is designed to extend radio signals generated by Distributed Power, HOT/EOT data equipment, and VHF Positive Train Control systems. Our Tunnel Link bi-directional amplifiers maintain an appropriate signal level while using a single repeater for all processes, ensuring a constant connection.
