This locomotive was built in 1949 by Robert Stephenson & Hawthorn and its industrial life was spent at the Rye House Power Station on the Lea Valley in Essex.
The power station was opened in 1953 and it was closed in November 1982. The locomotive carried the number ED6 there and classmate RSH 7598 number ED7. ED7 was subsequently scrapped but some parts were used on 7597.
The locomotive was bought into preservation by the 7597 Fund who then merged with the Lea Valley Railway Preservation Society but kept the name 7597 Fund. In 1971 the locomotive was moved to the Chapel & Wakes Colne Railway which in 1968 had become the East Anglian Railway Museum.
The locomotive was then returned to steam.
In 1975 the owning group changed their name to the Railway Vehicle Preservations and in 1981 it became a limited company.
In 1981 sought to change their home base and selected to move to the Great Central Railway (GCR) which offered 5 miles of former main line railway to operate 7597 and the operational stock on
For the next 8 years RVP members worked not only to restore its own collection but maintained thegrowing fleet of mark 1 vehicles owned by the GCR.
In 1989 the GCR began employing paid staff to maintain the service coaches. This enabled RVP members to return to restoring its own collection, and much more rapid progress was made.
Around the same time the GCR built Rothley carriage shed, and RVP moved there from Loughbrough in 1991.
After a period on loan to other railways (notably Peak Rail and Bodmin Steam Railway) the locomotive was sold to Peak Rail in 2001.
The locomotive was given the name Zebedee at Peak Rail because of the effect of the unusual coil-spring suspension.
In 2014 the locomotive moved to the Lincolnshire Wolds Railway.
Restoration work then restarted in earnest. The locomotive was stripped down to basic component parts and the chassis and axle boxes received attention. The frames were then re-united with the wheels and a start made on machining of new bearings for the motion. All the valve gear was overhauled and refitted and the cab and bunker prepared for painting.
By the Autumn of 2018 work on the bottom end of the locomotive was virtually complete.
