A new detailed model of the Metalair design pressure discharge bulk powder tank wagons used principally for bulk cement traffic. The developing technologies for pressure discharge systems and lining of wagons with materials promoting the clearing of the load allowed the design of self-clearing bulk powder wagons to be simplified. These cylindrical tanks replaced the BR Presflo covered hoppers and chevron style tank wagons in cement service.
This model is finished as a tank in service with the Blue Circle Cement group.
