Prairie wood-crib grain elevator (2002) A prairie icon Railways, inextricably linked to the development of agriculture in the great North West, brought considerable change to the virgin plains of the western interior. They provided the means for settlement on a large scale. Further, settlers were no longer compelled to freight in their provisions by wagon overland over long distances. Railways were the vital link for the community, taking the agricultural produce of the region to market and bringing in the necessities of life that could not be produced locally. The vertical grain elevator — of wood crib construction — was proven to be the most efficient means of handling grain. The concept was imported into Canada from the United States. As in the United States, lacking the capital to develop the grain handling system, the Canadian railways relied on elevator companies to erect and operate line-side grain elevators. In the early 1900s, a yearly production of 35 000 bushels (950 t) in a district was considered the absolute minimum threshold for the establishment and economic operation of a grain elevator. The standard granary of the period had an average capacity of 25 000 bushels (680 t). This had increased to 30 000 (820 t) and 35 000–40 000 bushels (950 t to 1090 t) by the 1910s and 1920s, respectively. In the early 1930s elevators of 60 000-bushel (1600 t) capacity were being constructed. The capacities of rural elevators were also increased, either by rebuilding or by constructing annexes.
