Gen-3 installations strengthen field communications

Norfolk Southern is installing new Gen-3 modems in locomotives to improve how we stay connected throughout the network. These devices help transmit data more reliably even in tough weather or remote areas so crews and systems can work together more efficiently.

This upgrade is part of a larger effort to enhance service and productivity in the field. With better connectivity, we can track locomotive performance in real time, support safety systems, and reduce delays caused by communication gaps.

The Gen 3 modem uses wireless technology to keep trains connected. This device is the main system that supports Positive Train Control (PTC), helping trains send and receive messages with the control center using the best available cellular or Wi-Fi signal.

This helps reduce network traffic and improves how trains are routed and managed.

Installations will continue through the end of the year. Once complete, Gen-3 will help us keep trains moving, make faster decisions in real time, and support safer, more efficient operations.
