The carriage side door comprises a side door body, the side door body is rotationally arranged on a door frame, the side door body comprises a door plate and an inserting piece arranged on the door plate, and the inserting end of the inserting piece extends in the direction away from the door plate; the first locking assembly comprises a first limiting piece, and the first limiting piece is used for being rotationally connected with the door frame and enabling the inserting end of the inserting piece to be inserted between the first limiting piece and the door frame; the second locking assembly is arranged on the side door body and comprises a base and a second limiting piece movably arranged on the base, the second limiting piece is selectively connected with the first limiting piece, and the second limiting piece is used for limiting rotation of the first limiting piece. According to the structure, the situation that the first limiting piece rotates due to vibration in the operation process of the freight carriage can be avoided, then locking failure of the first locking assembly on the side door body is avoided, and the reliability of the carriage side door in the operation process is guaranteed. And meanwhile, the structure can avoid using consumables such as iron wires for bundling and fixing, so that the cost is saved.
