Hi Alex,
Yeah you should be just like old times. I was born in 75 so I remember stuff from 1979 loads of 20's, 25's, peaks, 08's and some 31's. I used to have a pic of me in the cab of a 31 down at Murphy's oil terminal when they came to pick the tankers up. It is just a shame that the locos were slowly withdrawn from service. The only way nowadays to experience it now would be to go to a preserved railway.
