220Sa railcar

A two-axle 220Sa Us tank railcar is designed for transport of loose materials in pieces (e.g. gypsum stone, limestone, sand, clinker, gravel, slag). It is equipped with two tanks with total capacity of 25.6 m3 (2 x 12.8 m3). The railcar is loaded and unloaded by means of gravity respectively via charge manholes located on top of each tank and via discharge manholes placed in bottom of the tanks. Discharge flaps are opened from the railcar platform and closed using a special key on the railcar side. The railcar unloading system is designed so to allow for unloading of each tank individually or all of them at once.
