The invention relates to a braking system for a goods train. The braking system for the goods train comprises an air braking mechanism. The air braking mechanism comprises an air distribution valve (3) and a braking cylinder (5). The air distribution valve (3) is connected with a train pipe (1) and the braking cylinder (5) through a first braking branch pipe (2). The air distribution valve (3) is connected with an auxiliary reservoir (301) and an accelerated release reservoir (302). The braking cylinder (5) transmits acting force to brake shoes of the goods train. The braking system further comprises a three-way valve (4) and a hydraulic damper braking mechanism. An inlet of the three-way valve (4) is connected with the air distribution valve (3), and two outlets of the three-way valve (4) are connected with the braking cylinder (5) and the hydraulic damper braking mechanism correspondingly. Compared with braking systems in the prior art, the braking system for the goods train has the advantages of reducing abrasion of the brake shoes and damage to wheel treads and the like.
