The reason for their novel trip was to help raise money for the Railway Benefit Fund charity through the production of this DVD. So this is what is going to be on it.
The journey begins on the Thames estuary at Hoo Junction as the ED's set off on the outward route via Rochester, Chatham and Sittingbourne to Faversham.
From there they continue past the surviving semaphore signals at Canterbury East and Shepherd's Well before passing non-stop through Dover Priory station.
After a scenic run along the coast, the Class 73s enter Folkestone East sidings where they access the Folkestone Harbour branch. A large crowd greets the arrival of the very first GBRf locomotives to reach the little-used terminus.
To mark the occasion, the ED's depart in suitable style, horns blaring as they set off a series of detonators as they climb the steeply-graded branch on their diesel engines.
The Class 73s travel back to Faversham via a different route. From Dover, the 73s are back on diesel power again from Buckland Junction for the stiff climb up Guston Bank to Martin Mill.
From there the journey continues past the semaphore signals at Deal and Betteshanger before passing through Ramsgate, Margate and Whitstable.
At Faversham the locos re-trace the outward leg of their journey for the run back to Hoo Junction.
The programme will also feature a selection of charters and specials that have visited Folkestone Harbour over the last 20 years.
