Puffing Billy (locomotive)

Puffing Billy side-on at the Science Museum in London, its tall chimney and overhead beams showing how much of the machine sat on top of the boiler. William Hedley, Jonathan Forster and Timothy Hackworth built this 0-4-0 for Wylam Colliery near Newcastle upon Tyne in 1813 and 1814, and it worked there until 1862. It is the world's oldest surviving steam locomotive, older than anything else here by more than a decade. It is shown in the museum's Making the Modern World gallery; check with the museum before a visit that it is on display.
