The frames for 5161/25011 were laid down at Darlington Works during June 1961, being completed late in August 1961.
Works Visits (incomplete)
Although primarily allocated to the North Eastern Region and Scottish Region depots, 5161/25011 did occasionally stray beyond these boundaries:
1976: A new contract to move pipes from Leith Docks to several long distance destinations including Derby, Wisbech and Salisbury, and shorter hauls to Carlisle, Darlington, Law Jct, Maud & Montrose would provide much work for pairs of Haymarket Class 25’s. The Leith – Salisbury diagram involved the Scottish Type 2’s working as far as Didcot, examples noted were 25011 & 25026 (March 13th & 15th) and 25002 & 25317 (March 27th), 25018 & 25031 (April 10th), 25026 & 25092 (April 24th), the locomotives generally returning north light, at least as far as the Birmingham area.
1977: 25011's recorded passenger working number about a dozen, although no doubt there are many more out there. On August 24th along with 27032 it worked 16.54 Glasgow Queen Street - Dundee and 19.38 return, a total of 166 miles, its highest daily mileage for a recorded passenger working.
1978: During August 25011 was noted at Derby Works receiving minor attention. After release the locomotive was sent off in the opposite direction to its home depot in Scotland! It was noted on the 15.55 Bristol - Plymouth parcels on September 7th, working as far as Exeter, being replaced here by 25155. It continued its westward march by working the 19.30 Exeter - Paignton!
1979: On May 12th 25011 was noted with buffet car SC1706 at Millerhill headed for the work taking place at Penmanshiel following the recent collapse of the tunnel.
1980: Its last recorded passenger working was on November 7th working the 17.12 Aberdeen - Stonehaven.
The last days
All the remaining Class 25/0's were taken out of service and withdrawn during December, including 25011. 25011 ended its days out of service at Haymarket, by early January it was at Millerhill.
From February 9th - 11th 1981 25010 with 25011, 25023 & 25087 were moved from the Scottish Region (Millerhill) to Swindon for scrapping. At least as far as York (and possibly further southwards) 25010 was used to power the consist, perhaps giving 25010 the dubious honor of being the last Class 25/0 to remain in an operational condition. It is believed the convoy reached Swindon by February 11th. 25011 was broken up at Swindon during March.
