The invention provides a rail assembly and a sliding door. The rail assembly comprises a rail, a buffering piece, a triggering piece and a sliding piece. The rail comprises a first clamping groove, a clamping block and a guide groove. The buffering piece comprises a touch block which extends out from the interior of a limiting groove and is capable of moving along the limiting groove. The triggering piece comprises a stirring block. After the triggering piece moves towards the tail end of the rail, the stirring block makes contact with the triggering block, the buffering piece is triggered to work, the moving speed is reduced, and after the triggering piece gets away from the tail end of the rail to move, the stirring block gets away from the triggering block. The rail assembly further comprises a cover plate, a second clamping groove is formed in the cover plate, and the second clamping groove and the clamping block are clamped. The sliding door is provided with the above rail assembly. By means of the rail assembly and the sliding door, a hidden buffering function is achieved, and parts are easy to install and replace.
