A new thumper eh?
Indeed, in this the 25th Anniversary year of the demise of the last 70 class, a photo of that very set, with no 75 River Maine leading, a couple of weeks before the set was wrecked internally by drunken Apprentice Boys and withdrawn. As 2011 is likely to be the last year in which its venerable 45 year old 4SRKT power unit will still be operational in a 450 class, it's a poignant picture

Amazing to think that the 450s that were born out of these sets have now been running for 5 years longer than the 70s managed!
