Canadian Pacific Railway Completion

The driving of the last spike on May 22, 1885, at Craigellachie, British Columbia, marked the completion of the Canadian Pacific Railway, fulfilling a promise made at Canadian Confederation. Led by financier Donald Smith and engineer Sandford Fleming, the project overcame immense challenges including the Rocky Mountains and vast prairies using thousands of laborers, many Chinese immigrants. The railway used powerful 4-4-0 steam locomotives initially and facilitated massive westward expansion, resource transport, and national unity. It connected Montreal to Vancouver in under five days, transforming Canada's economy and enabling settlement. The CPR's success spurred further rail development across North America and symbolized engineering triumph in the late 19th century.
