History 
In the 1870s as the railroad expanded, settlers were drawn to the area to build their homes and set up their businesses.  The community was originally called Ralston's Colony (after John Ralston, an early settler). Around 1877 it was decided to rename the community Rapid City. Since the community was on the banks of the Little Saskatchewan River and it was a "rapid stream" they chose "rapid" and "city" reflecting the optimism of those early settlers. During the 1880s many awaited the arrival of the Canadian Pacific Railway lines Canadian transcontinental railway that would bring with it a certain building boom. While people assumed that the projected northerly route away from Portage la Prairie, Manitoba would take it through Rapid City and its narrow river crossing, the route suddenly changed to a more westerly route. This brought it through the location of present-day Brandon, resulting in the boom and growth of that city.

Education
