Or to give it its full title: 1956 Populations and Estimated 1981 Populations of the Four Natural Sectors of Greater Winnipeg also General Form of Rapid Transit System Designed to Meet Basic Transit Needs of 1981 Notwithstanding Street Congestion.
A lovely old planning map from the “Future Development of Public Transit in Greater Winnipeg” report by Norman D. Wilson. It shows the very general concept of a proposed rapid transit system along with the expected population growth in the greater Winnipeg area in the far-off distant future of 1981. The system – as outlined in the report, presumably – is expected to handle the transit needs of that future, “notwithstanding street congestion”.
