Transportation

Signaling, traffic management, tunnel ventilation and terminal automation for rail, transit, highway, port and airport operators. The systems move people and cargo on a fixed schedule, and they are increasingly connected to reach it.

The exposure

A signal fault stops the whole line.

Transit and port networks grew by bolting remote access onto field equipment spread across miles of right-of-way. Wayside cabinets, traffic controllers and crane PLCs often sit on flat networks reachable from the business side.
