On my forthcoming layout, I'm looking to use a nicely weathered GYP Class 37. My interest is in trying to identify any GYP Western Region Class 37's that survived into 1970 in this livery, as my layout is set in 1970/1. In his excellent recent book, From Green To Blue, Russell Saxton mentions that the last surviving GYP was Scottish based D6841,in the summer of 1970. There is a picture on the internet of D6841 in July '70.
So far I've been unable to locate any conclusive info. There are pictures of 6875, 6879 and D6988 in GYP on the internet, from Aug '69. Also similar pictures of 6600, D6890 and D6906 from Sept '69. But so far no Western Region pictures from 1970.
Railway Observer suggests that 6876, 6969,6978,6987,6988,6995,6996 and 6997 may have survived into 1970 in GYP, as all were noted going GFYE during 1970. However Railway Observer info always has some degree of time lag.
I would be really grateful if anyone has some definite sightings, or pictures of GYP Class 37s in 1970, or indeed late '69. Although I'm mainly interested in Western Region locos, I'd still happily receive info on Eastern or Scottish locos.
Many thanks.
