Re 360, I am fully aware you have a unit on maintenence but for 21 units that's only 1, and GE managed to turn out 20 units.
IF you have "a couple out for repainting" that's still 18 - so something is badly badly wrong if there are another 6 stopped.
This is 60% availability only which is appalling for a type that generically can return 96%.
2 are on maintenance each day, 2 are at eastleigh for painting ,the remaining 5+ plus each day have faults bad enough to not be used.
They are 16 years old now and require a badly needed overhaul. Get used to it because this is how its gonna be for some time to come.
