First steam train in Canada

On August 3, 1839, the Champlain and St. Lawrence Railroad launched the first steam locomotive service in Canada, connecting La Prairie on the St. Lawrence River with Saint-Jean-sur-Richelieu. The locomotive, named Dorchester, was a 0-4-0 built by the Newcastle firm of Timothy Hackworth. This 16-mile line marked a pivotal shift from horse-drawn to steam power, overcoming engineering challenges like wooden rails and swampy terrain. It facilitated trade between Montreal and New York via Lake Champlain and inspired further rail expansion across British North America. The success demonstrated the viability of railways in harsh Canadian winters and laid groundwork for the Grand Trunk Railway network. Enthusiasts note the Dorchester's vertical boiler design as an early innovation that influenced subsequent North American locomotives.
