Welcome, pop-pickers…
One of the very very few UK diesel LPs ever made, Diesels in the Highlands (ZTR 147) was issued on the Argo/Transacord label as an Argo/Stavely Makepeace recording.
The label was set up by highly acclaimed film sound recordist Peter Handford; the recordings for the three diesel records released (Sounds of the Westerns; Sounds of the Deltics and Diesels in the Highlands) were done by Nigel Fletcher and Rob Woodward of the bands Stavely Makepeace and Lieutenant Pigeon.
This stereo record captures Class 26s; 25s, 40s , 47s and a 6 car DMU on the Far North lines including the Kyle line, the freight line from Aberdeen to Fraserburgh and Carrbridge to Inverness. Featured are 25246+25079; 26010; 26012; 26013; 26014; 26015; 26030+26009; 26031; 26032; 26036; 26042; 26044.
To date, the recording hasn’t been re-released digitally. Copies occasionally turn up on ebay at around a tenner; buy one and perplex the neighbours!
You can find out more about the history of the recordings via the Transacord Digital site and of some other railways recordings on Ian Strange’s site.

Nice nod to The Members in the title!
I remember being amazed and delighted when I discovered the unexpected connection between my Dad’s copy of Sounds of the Westerns and my 45s of Mouldy Old Dough and Desperate Dan! The locomotive beat definitely got into a lot of Lieutenant Pigeon songs (along with echoes of pub pianos and traditional fairgrounds). Train sounds open and close Lt P’s Rockabilly Hotpot.
