Canadian Pacific Railway Reaches Calgary

On August 17, 1884, the first CPR train reached Calgary from the east, part of the push to complete the transcontinental line by 1885. Using 4-4-0 locomotives and facing Rocky Mountain engineering feats like the Spiral Tunnels later, the arrival transformed Calgary from a frontier outpost into a rail hub. Key figures included William Van Horne. It facilitated immigration, cattle trade, and resource extraction, cementing Canada's national unity through rail infrastructure.
