The nineteen year three month career of D5235/25085 saw allocations to all regions apart from the Southern.
Built: BR Derby Locomotive Works.
D5235 was new to Toton (16A) on December 21st 1963. Further transfers were:
February 1964 to Nottingham (16D).
Renumbered April 20th 1974.
25085 had reached Derby Works during March for engine repairs, these appear not to have been approved and the locomotive was withdrawn whilst at the Works. It would be scrapped at Derby by the end of May 1983.
Works visits (records incomplete).
Noted Derby Works December 1966.
The tests revealed the location of the grilles on the Derby designed build allowed for much more debris to reach the filters (especially the lower ones), clogging them quicker, leading to decreased air quality within the engine compartment, and so potentially affecting performance and engine wear. With over two hundred Class 25's still on the order books the redesign of these areas would result in a cost savings in the long run, in addition to a better working environment within the cabs, and providing less cluttered look to the locomotive's exterior.
One unique feature of these machines was their being equipped with steam heating equipment, all the following Class 25's would be without boilers.
D5234 & D5235 were sent out on their test runs to Corby on December 4th 1963.
After nine years allocation to depots along the Midland mainline 5235 transferred to Eastfield during August. By October 5235 had moved south to Tinsley.
On November 5th the 06.43 Peterborough – Kings Cross arrived behind 31108 & 25085.
25084 & 25085 were in Derby Works for repair between April & June.
25238 & 25085 were noted at Oxford on August 5th on the long distance Leith - Yeovil pipe train, presumably the Class 25's came off at Oxford. Two days later 25085 was noted at Leicester.
The 8M36 Tyne Yard - Carlisle freight was hauled by 25085 on October 25th.
25085 was at Glasgow Works during August & September for an Intermediate repair. 25085 was noted on the 15.57 Dundee - Glasgow Queen Street on September 21st.
25085 was in charge of the 1A53 17.12 Glasgow - Ayr on April 25th.
On July 10th 25010 & 25085 worked the Perth - Kensington motorail as far as Mossend. The next day 25085 came to the rescue of an ailing 47210 working the 17.40 Edinburgh – Inverness. The Class 25 was sent from Perth to push the failure from Stanley Junction to Murthly, here detaching the failure before heading out alone to Dalwhinnie where 47040 was added to the train for the run to Inverness.
After five years on the Scottish Region 25085 transferred to Springs Branch during October.
Engineering work at the south end of the WCML led to diesel substitutions, on March 1st 25085 covered one brief working between Stonebridge Park and Euston whilst the 20.45 Barrow - Euston was worked forward from Bletchley by 25084 on 3rd and 25085 on 8th.

The 16.02 Crewe - Cardiff was worked by 25085 on June 26th, the next day it worked the 17.10 to Crewe.
On August 1st 25085 & 25032 worked a ‘Welsh Marches Pullman’ charter between Shrewsbury and Chester, following the failure of Black Five No.5000.

On August 22nd 25085 was diagrammed for the 10.14 Perth - Motherwell, it only got as far as Gleneagles before requiring the assistance of 20121.
A short trip for 25085 was working the 14.05 Blackpool - Crewe as far as Preston on September 5th.
An Open Day at Warrington Central on October 11th featured 25085, 40115, 47334, a Class 08 and a number of other vehicles.
The failure of 45009 at Derby on October 15th whilst working a Newcastle - Bristol service led to 25085 taking over as far as Birmingham - this may have been 25085's last passenger working.
