May 2024

D8568 has now returned to the Severn Valley railway after a successful visit to the Kent and East Sussex railway. The loco performed well with just one small problem, a leaking water pump seal that required the loco to take on water a number of times.

On its return to the Severn Valley railway the water pump was removed and is now being repaired and hopefully the loco will be ready for the Severn Valley Diesel gala in May. It also has several planned running days for the rest of the year.

D8568 is the unique locomotive in our collection, being the only surviving example of the Clayton Type 1's which numbered 117 in total. D8568 is also our only diesel-electric loco.

D8568 is based on the Severn Valley Railway and is used throughout the running season, at diesel events.
