Abstract: A freight coupler (100) is arranged on a first rail vehicle to interconnect the first rail vehicle with a second rail vehicle. The freight coupler (100) has outer and inner portions (110; 120). The outer portion (110) includes a first locking mechanism (115) of a coupler 5 head, which first locking mechanism (115) is configured to be connected to a second locking mechanism (1115) of a counter-coupler head of the second rail vehicle. The inner portion (120) includes a mounting structure for mounting on the first rail vehicle. At least one shear member (131) interconnects the outer and inner portions (110; 120) mechanically. The at least one shear member (131) is configured to break in response to a draft force (FD) exceeding a first threshold level, which draft force (FD) pulls the outer and inner portions (110; 120) away from one another so as to disconnect the outer and inner portions (110; 120) mechanically from one another and allow the outer portion (110) to be physically separated from the inner portion (120). The at least one shear member (131) is integrated in a mechanical interface (200) that is configured to absorb buff forces (FB) between the inner and outer portions (110; 120), which buff forces (FB) are absorbed without the at least one shear member (131) being broken, and which buff forces (FB) exceed the first threshold level.
