In the British children's TV series 'Ivor the Engine', what was the name of Ivor's driver?

'Ivor the Engine' is a British stop motion animated television series created by Oliver Postgate and Peter Firmin's Smallfilms company. It follows the adventures of a small green steam locomotive who lived in the "top left-hand corner of Wales" and worked for The Merioneth and Llantisilly Railway Traction Company Limited. His friends included Jones the Steam, Evans the Song and Dai Station, among many other characters.

Edwin Jones is Ivor's driver, he is better known as Jones the Steam. He is a cheerful and kind-hearted man who perhaps sympathises more than most railway staff with Ivor's idiosyncrasies. Postgate and Firmin describe him as "an ordinary engine driver who is there to cope with whatever needs to be coped with". People who are new to the area find him rather eccentric for talking to his engine.

When not driving Ivor or helping the engine with his latest flight of fancy, he enjoys fishing and day-dreaming.
