The invention discloses a longitudinal telescopic railway wagon top cover. The top cover comprises a rail assembly, a sliding block and shed rod system and a driving system. Rails are integrally arranged on two sides of a side wall of a vehicle body in an inverted-L shape, and the sliding block and shed rod system comprises a tail sliding block and shed rod assembly, a driven sliding block and shed rod assembly and a driving sliding block and shed rod assembly which operate along the rails. Each assembly comprises a shed rod for supporting and connecting awning cloth and a sliding block whichruns along the rails and supports the shed rod; power sources such as a motor or a hydraulic motor and the like are adopted, the driving sliding block and shed rod assembly are driven by a transmission mechanism to move on the rails, and the awning cloth covers an open top; and when the top cover is opened, the transmission mechanism drives the driving sliding block to directly act on the driven sliding block, and recycling of the shed rod and the awning cloth is achieved. Due to arrangement of the rails, the shed rod can be conveniently placed on an outer side of an end wall of a wagon body after being retracted, and the wagon body is fully opened to adapt to tippler unloading conditions; and the top cover is made of light-weight soft awning cloth, the weight is light, and maintenance cost is low.
