TRAINLINK?II monitors key last-car information, including brake pipe pressure, end-of-train motion, battery condition, and communication and marker light status information while adding
end-of-train emergency braking capability. The system comprises a locomotive cab unit and an end-of-train unit. Options include RS-232 communications, proximity warning system, undesired emergency
detection, HELPERLINK (electronic air hose for pusher locomotives) and TRAINLINK ES, which provides rear-end service brake pipe reductions for improved train braking.
