TB/T 456—2008 ＂Couplers and coupler yokes for railway locomotive and rolling stock＂ comes from merging and modifying the two standards, one is TB/456—1991 ＂Technological Specification of Coupler and Coupler Yoke＂, the other is GB/T 17425—1998 ＂Purchase and acceptance of couplers and coupler yokes for freight service＂. After introducing the development status of domestic and foreign couplers and coupler yokes for railway locomotives and rolling stock, the author comprehensively reviews the modification of the standard, and gives suggestion on the implementation of the standard.
