Top 10 Oldest Operating Steam Locomotive Railways Worldwide

The top-ranked Swansea and Mumbles Railway, established in 1807, predates the invention of George Stephenson’s first practical steam locomotive by approximately seven years. Interestingly, it was not initially designed for humans, but for hauling limestone. As of 2026, this line stands as a living testament to over two centuries of industrial evolution, having transitioned from horse-drawn carriages to steam power and eventually electric traction. While subsequent entries on this list largely emerged in the mid-to-late 19th century, the Swansea and Mumbles line functions more like a prehistoric 'industrial monument.' Although modern infrastructure has superseded it, its status as the world’s first public passenger railway remains an unparalleled milestone in industrial history.
