These silos of concrete vertical cell construction, were the second type to be constructed between 1935 – 1950 by the Grain Elevators Board, and are located at railway sidings on those lines intended to service a terminal elevator at Williamstown. This terminal was never completed, as it was determined that the terminal at Geelong could adequately handle all exports.
The bins on the 57 Williamstown type silos in Victoria have flat concrete roofs cast in situ. The units have bin diameters varying from 8.2 metres to 10.1 metres, with wall heights of 22, 25.9 or 30.5 metres, and capacities varying from 2000 to 4500 tonnes. Receiving and outloading rates are a nominal 120 tonnes per hour.
