A four-axle 408S Uacs tank railcar is designed for transport of powdered materials with bulk density of 0.6-1.4 t/m3 (e.g. cement, lime, blast-furnace ash). It is equipped with four tanks with total capacity of 50 m3 (4 x 12.5 m3). The railcar is loaded by means of gravity via charge manholes located on top of each tank and unloaded pneumatically at maximum working pressure of 0.25 MPa. The railcar unloading system is designed so to allow for unloading of each tank individually or all of them at once.
