In a recent announcement, a steam locomotive has been declared one of the oldest in the world after researchers discovered it was built 10 years earlier than originally thought.
The George Stephenson-built Killingworth Billy was believed to have been constructed in 1826.However, a new investigation of the engine, on show at North Shields Stephenson Railway Museum, suggests it was constructed in 1816.That would make it the third-oldest surviving locomotive in the world.
It would also be the oldest surviving locomotive built by Mr Stephenson and the oldest surviving with a standard gauge.(Wikipedia Image of “Billy” at the Stephenson Railway Museum.)
