Several features are added include followings:

• Less small contour slack and control of vertical interface movements reduced the wear of the coupler head surfaces, extending the knuckle service life. F coupler has only 3/8 inches of contour slack when linked by two new couplers, compared with the Type E and Type E/F as 25/32 inches, it will result in the improvement of the vertical dynamic mechanical performance of coupler, reduction of the vertical impact of two couplers and extension of the working life of wagon and its parts.

• Improved the performance of wagon when running at the curved rail track and automatic center alignment. Using the shank butt alignment shoulders assist in keeping the coupler centered and car aligned automatically under heavy duty load when running at the curved rail track.

• Vertical round pin connection and spherical butt end will make more convenient for assembly than the E coupler Cross Key structure, and also improve the running performance at curved rail track.

• More reliable lock lift mechanism: two types of anti-jumping function integrated in the lock lift will keep the coupler locked securely.

• Frontal interlocking mechanism at the coupler head can improve the coupling strength, and protect the knuckle and transmit the force to assist in dumping the wagon.

• Frontal bottom support shelf is preventing happen of disconnecting of coupler from falling to the railroad and thereby becoming a serious derailment accident.
