Inside Crewe works(paint shop)

I found this old 35mm image of the Inside of what was known as the paint shop at Crewe works,I cannot recall when the picture was taken but have a feeling It would of been In the early 90s at one of the open days or when as a youngster fences were for hopping over to get a closer look at engines under repair at the Works.I find the whole scale of what the works once was fascinating and find it hard to visualise what the place must of been like at Its peak, that is now such a long way in the past.
