45 057 was a recent arrival in the scrapyard at Derby Locomotive Works when photographed in March 1985. It had been withdrawn by BR on 21/01/1985. It wasn't dealt with at the works and instead was sold for scrap to Vic Berry's of Leicester. It moved from Derby to Leicester in January 1987 before being broken up at the beginning of March 1987.
25 319 was a former Crewe Diesel allocated machine and was withdrawn on 20/03/1983. It was moved to Derby Works as suitable for conversion to an ETHEL (Electric Train Heating unit Ex Locomotive) and was destined to become 97 251 but on inspection it was deemed unsuitable and 25 305 instead took its place. It languished at Derby Works in the scrap lines until being moved to Swindon Works where it was cut up on 24/07/1985.
As a side note if the 1J24 headcode carried by 25 319 was one of its last workings that headcode related to the 10.10 SO London Euston to Aberystwyth on the summer timetable 1982 which it could conceivably have worked with a sister class 25 from Shrewsbury through to Aberystwyth.
