The invention discloses a railway wagon compartment and a top-cover opening/closing driving mechanism thereof. The top-cover opening/closing driving mechanism comprises two rocker arms, wherein the two rocker arms and an end wall are hinged each other through a connecting rod; one of the rocker arms is driven by an air cylinder to rotate around a hinged point of the rocker arm and the end wall; when a cargo inlet of a compartment body is closed, the two rocker arms are parallel to each other, and a hinged point of one of the rocker arms and the connecting rod is positioned above a connecting line of the hinged points of the two rocker arms and the end wall; a hinged point of the other rocker arm and the connecting rod is positioned under the connecting line of the hinged points of the two rocker arms and the end wall. The rotating degree of each rocker arm is determined mainly by an inclined angle formed by the connecting line of the hinged points of the two rocker arms and the end wall, and a connecting line from the hinged point of the rocker arm and the end wall to the hinged point of the rocker arm and the connecting rod when the top cover is closed. Namely, the opening degree of the cargo inlet of the compartment can be adjusted by adjusting an included angle formed by an active accessory arm and a connecting line of the hinged points of the two rocker arms and the end wall, so that a problem that in the prior art, because a space for the connecting line of the hinged points of the two rocker arms and the end wall is fixed, the opening degree of the cargo inlet is too small is solved.
