Puffing Billy is one of the early built steam locomotives from the Science Museum.
Puffing Billy was built in 1813 and completed a year later for Christopher Blackett of the Wylam Colliery to replace horses from the tramways. The engine remained in service until 1862, when Edward Blackett lent it to the Science Museum in London.
The engine later appeared in Hashire! The "Thomas the Tank Engine and Friends" Steam Locomotive is Alive!, where he tells host Gaku Hamada about steam locomotives.
