First train on the Canadian Pacific Railway reaches Calgary

On June 24, 1883, the Canadian Pacific Railway's construction train reached Calgary, then a small settlement in the Northwest Territories. This milestone was part of the ambitious project to link eastern Canada to the Pacific coast, overcoming Rocky Mountain engineering challenges with helical tunnels and trestles. Led by William Cornelius Van Horne, the arrival spurred rapid growth, transforming Calgary into a major rail hub. The event connected remote regions, boosted immigration, and supported national unity following Confederation, with lasting impacts on Canadian economic development.
