required that the fabrication casting material be of open hearth or electric furnace grade "B" steel with specific metallurgic requirements to insure proper tensile strength and reliability of the coupler and its moving parts. In order to govern uniform standards for the interchangeability and the proper relation between fitting parts, the A.R.A. Committee on
Couplers and draft gears designed and distributed templates, gauges, and master guides to assure the proper interchangeability and fitting of parts to maintain the proper operation of various multi-source manufactured railway couplers.

1063:. Its success in promoting switch-yard safety was stunning. Between 1877 and 1887, approximately 38% of all railworker accidents involved coupling. That percentage fell as the railroads began to replace link and pin couplers with automatic couplers. By 1902, only two years after the SAA's effective date, coupling accidents constituted only 4% of all employee accidents. Coupler-related accidents dropped from 11,710 in 1893 to 2,256 in 1902, even though the number of railroad employees steadily increased during that decade.

Knuckle couplers of the 1880s and 1890s had a chaotic mixture of proprietary internal components, but all had the standard MCB external contour, making them compatible. There was a multitude of makes and models — Burns, Climax, Gould, Miller, Sharon and Tower. Some worked better than others.

The external contour of Janney knuckle couplers was the first aspect to be standardized by the MCB in the 1880s. Prior to this, there was a chaotic variety of constantly evolving and proprietary external contours and internal components. In 1893, manufacturers standardized on the MCB-5 or Type C
