The Janney coupler, later the Master Car Builders Association (MCB) coupler, [19] now the Association of American Railroads (AAR) coupler, is also commonly known as a buckeye, knuckle, or Alliance coupler. The AAR/APTA TypeE, TypeF, and TypeH couplers are all compatible Janney couplers, but used for different rail cars (general freight, tank ...
With gooseneck couplers or offset shank couplers, the horizontal centerline of the coupler head is above the horizontal centerline of the coupler shank, or shaft, and the draw gear. This arrangement is designed for use with low-floor freight cars, to lift the coupler head high enough to match the couplers on other rolling stock. [18]
Russian SA3 couplers on Russian cars and some heavy-duty freight cars "Unilink couplers" (SA3 clone with UIC-style screw link) or "Vapiti" (SA3 clone with movable link arm for English couplers) couplers on the majority of locomotives; compatible with SA3 and English (UIC) center hook
Three-link coupling on an antique tank wagon. There is no hook at the end of the chain, nor is there a turnbuckle. A peculiarly British practice was the "loose-coupled" freight train, operated by the locomotive crew and a "guard" at the rear of the train, the successor to the brakesman of earlier times.
Since bogie exchange technology has progressed, this allows for cars with SA3 couplers to regularly operate on the standard gauge tracks. A special converter car is inserted between standard and Russian gauge cars for this operation, with different couplers (SA3 and standard) on either end. Although these coupling freight cars have room for ...
Need automatic couplers that can be uncoupled without man going between. On January 1, 1898, it will be unlawful for a common carrier used for interstate commerce to haul or permit to be hauled any car that is not equipped with couplers coupling automatically by impact and which can be uncoupled without a man going between the ends of the cars.
The couplers automatically lock when cars are pushed together, but workers must go between cars to hook up the air lines for the pneumatic brakes and connect cables for head-end power and other communications. To separate cars, a worker must use a lever to move the locking pin that keeps the coupler closed.
The Type 10 includes "horns" to aid coupling on curves and include a function to provide standardised automatic air-brake connections; the coupling horn is often visible poking out at the front of the nose of high-speed trains. For European freight, the TSIs mandate buffer and chain couplings at specified heights.
