Abstract
Disclosed is a railway hopper car comprising a car body (6), a top cover (1, 2), a bogie (24), a braking device (21), a coupler buffer device (22), and a bottom door (25, 28) and a bottom door opening and closing mechanism (23) mounted at a discharge port at the bottom of a chassis. The railway hopper car further comprises a longitudinal saddle (31) disposed in the center of the car body (6) in the length direction thereof and arranged along the longitudinal direction of the car body (6). By providing the longitudinal saddle (31), the sequential requirement to close the left bottom door (25) and the right bottom door (28) is eliminated, thereby simplifying the structure of the linkage bottom door opening and closing mechanism and reducing manufacture and maintenance costs thereof.
