July 1961 finds D5157 standing at Darlington Works shortly after completion. D5157 was one of a batch of twenty five machines built at Darlington, upon delivery the entire batch was allocated to Thornaby to assist in the removal of local steam working in the Middlesborough area. This batch of machines, later to become the Class 25/0's were a transition between the 75mph 1,160 hp Class 24's and the 90mph 1,250 hp Class 25/1's. D5151 - D5175 was powered by the uprated 1,250 hp 6LDA28B Sulzer 6 cylinder engine, but carried the same traction motors of the earlier Type 2's but with a modified gearing to attain the higher maximum speed. This difference in characteristics tended to keep the sub-group allocated together for most of their lives.
The nineteen year three month career of D5157/25007 included allocations to Eastern and Scottish Region depots.
Built: BR Darlington Locomotive Works.
D5157 was new to Thornaby (51L) on July 7th 1961. Further transfers were:
December 1961 to Gateshead (52A).
Renumbered May 1974.
25007 was moved to Swindon Works on November 6th 1980 with 25006, being withdrawn whilst at the Works. 25007 was broken up at Swindon during the third week of September 1982.
Works visits (records incomplete).
Noted Darlington Works April & May 1963.
During December Gateshead sent D5112 & D5113 to Thornaby in exchange for D5156 & D5157.
D5157 stands at Thornaby not too long after delivery. It has gained a good coating of dust and a '51L' shed plate on the cab front. In contrast to the first view, this one reveals the other side of the locomotive, with two rows of four air filters, in contrast to the three/four arrangement on the other side. Although this batch of locomotives were not boiler equipped they carried a through steam pipe, the steam pipe fittings being clearly visible on the buffer beam. In later years this connection would be removed.
The allocation of this build to Darlington was probably due to Derby being preoccupied with the later batch of BR/Sulzer Type 4's (the Class 46's), and its responsibility for overhauling much of the growing LMR fleet of diesels. The bodyshell of this batch was very similar to the previously built Type 2's, though in the Class 25/0's no boilers were fitted, thus the boiler water tank was omitted, but the ventilation grille for the boiler room remained! Darlington, in painting the locomotives picked out the grilles in grey, as Derby & Crewe had done on the bigger Type 4's.
The transfer of 25006/07/08/11 to Tinsley during February brought all twenty five members of the Class 25/0's together again.
On July 26th Ipswich was host to 25007 & 25021 passing through with the empty stock of a Glasgow - Brandon troop special.
To cover the withdrawal of a number of Scottish Class 24's 25005 - 25014 moved from Tinsley to Eastfield in August.
Glasgow received 25007 for intermediate repairs during January & February.
On July 10th the 21.40 Edinburgh - Carstairs was worked by 25007.
Considerable mileage was covered on August 18th when 25007 & 25062 worked an SRPS special throughout from Dundee via the Forth Bridge and Falkirk to Oban and return.
On September 11th an early afternoon Dundee - Glasgow Queen Street relief was worked by 25007.
During May 25006 & 25007 were transferred to Haymarket.
On June 14th 25007 worked the 17.12 Perth - Arbroath and the 18.33 Arbroath - Dundee.
25007 was used on July 12th to take forward the 14.24 Scarborough - Glasgow Queen Street relief from Edinburgh, this may have been 25007's last passenger working. At the close of the summer timetable in September (18th?) both 25006/007 were stored unserviceable at Millerhill.
25006 & 25007 were also retired during December, though they had spent the last three months stored at Millerhill. Early in November they were moved to Swindon Works.
This page opened with an ex-works view of D5157 at Darlington, it ends twenty one years later with a view of 25007 at Swindon, very near to the end.
During March 2016 a builders plate from 25007 sold on Ebay for GBP536.55. A plate sold at the same time from 25188 only reached GBP275.00
