It shows signs of being modernised during it's working life. After all, it was old technology by 1829 when Rocket emerged from Stephenson's works in Newcastle. (I guess we've all had similar experiences with computers!)The photo shows that to bring the loco up to date it has had springs fitted to the axles and the boiler had been modified with the addition of a smokebox. A look inside the smokebox would reveal that the boiler has been changed to a firetube boiler, which it wouldn't have had when new.

When it's working days were over, it was displayed at the north end of Robert Stephenson's magnificent High Level Bridge over the Tyne, near the celebrated Bridge Hotel (A hotbed of North Eastern steam loco preservation). Later it was plinthed at Newcastle Central Station and then moved to the old Museum of Science and Technology at Exhibition Park on Newcastle's Town Moor. Today it is proudly displayed at the Stephenson Steam Museum in the care of Tyne and Wear Museums Service.
