Positive Train Control
Positive Train Control (PTC) systems are a series of wireless networks that continuously monitor all train movements and provide fail-safe signaling. In the event of issues such as loss of separation between trains, wayside/trackside equipment malfunctions, operating outside established limits or excessive speed, PTC systems will implement immediate action to avoid potential accidents.
CDM Electronics is a leading distributor of premium coaxial cable and interconnect solutions to help PTC become a reality where it is currently planned, and to maintain the highest level of performance where the system is already in place. CDM can also provide custom power, communications, and data transmission cable assembly solutions for PTC infrastructure, along with box builds to support operations and signal requirements.
