They are designed with mechanical features which reduce slack in normal operation and prevent telescoping in derailments, yet remain compatible with other Janney types used by North American freight railroads. Like all Janney couplers, the Tightlock is \"semi-automatic\" with the couplers on cars or locomotives automatically locking when cars are pushed together. However, most tightlock couplers are not fully automatic, as workers still need to go between cars to hook up the air lines for the pneumatic brakes, and connect cables for head-end power and other communications. Also, to separate cars, a worker needs to use a lever to move the locking pin that keeps the coupler closed. In Europe, some operators experimented with making fully automatic tightlock couplers by adding integral pneumatic and electric connectors, but these connections experienced reliability issues. Most operators who experimented with fully automatic tightlock couplers have now switched to the more common fully automatic Scharfenberg coupler. Janney Type H TightLock coupler standards were established by the Association of American Railroads. Management and development of the standard was transferred to the American Public Transportation Association in 1971 when passenger service was nationalized in the United States from most private railway companies to Amtrak. On a standard-gauge railway, the nominal mounting height for the coupler (rail top to coupler center) is 33 inches (838 mm), with a 34+1\u20442 \u00B1 1 inch (876 \u00B1 25 mm) maximum height on empty cars and 31+1\u20442 \u00B1 1 inch (800 \u00B1 25 mm) minimum height on loaded cars."@en .
