This must be South West Waters fault. The wash plant has been in operation for years, if not Decades but problems have only developed in the last 3 weeks?
Sounds like SWW playing the blame game here instead of sorting the problem, particularly as the plant is used at night!!!
The Laira Wash plant has been there at Least 25 years,
I remember in late 1980's Laira sent a rake of
MK▸ II's through the wash plant, ok it happened all the time, but the Loco, a class 50 had been painted only the day before and newly painted stock shouldn't go through wash plants.
However timing is so important.
Due to a fault the Exmover Spray was working but the water rinse WASN'T.
Two or three days later the Class 50 was back in for REPAINTING as it looked awful, all the new paint had lifted.
Seem to remember the MK II's were gleaming.
