The seventeen year ten month career of D5176/25026 was spent allocated to depots on the Eastern, London Midland & Scottish regions.The allocation history for 25026 indicates a flexibility not seen with the Class 24s or Class 25/0s, particularly after its virtually uninterrupted eight year stint on the Eastern Region came to an end.
Built: BR Darlington Locomotive Works.
D5176 was new to Holbeck (55A) on January 8th 1963. Further transfers were:
June 1963 to York (50A).
Renumbered February 23rd 1974.
25026 was the 50th Class 25 withdrawn, one of seventeen retired during November 1980.
After withdrawal 25026 was moved (see details below) to Swindon Works on January 12th 1981 broken up there by the fourth week of March 1981.
25026, 25103/137, 08027 on January 12th 1981 Toton - Swindon Works by 31289.
Works visits (records incomplete).
Noted Derby Works July 1966.
After completing its order of twenty five Class 25/0s (D5151 - D5175), there was a break of about four months between the delivery of the last Class 25/0 No.5175 and the laying down of the frames for D5176, as part of the Darlington order for D5176 - D5185, these would be the first of the Class 25/1s, being equipped with the 1,250hp engine in conjuction with the compact lightweight AY253 traction motor. The frames for the first of these ten locomotives, D5176 were laid down in August 1962.
The cost of these locomotives (as supported by documents now held at the NRM York) was GBP77,917, of which GBP43,314 was the cost of the Sulzer engine. By the time of Darlington's next order (D5223 - D5232; which were originally to be built at Derby) the cost had risen to GBP79,018. Comparable costs were GBP78,488 for the 5700 series MetroVick Co-Bos, GBP63,953 for the NBL Class 22 diesel hydraulics & GBP69,666 for the NBL Class 21 diesel electrics.
Although this order was good news for the workforce at Darlington, bad news arrived on September 19th 1962. A review of the British Railways workshop capacity had been carried out and its recommendations demanded a reduction in the labour force from 56,000 to 38,000 with a number of workshops scheduled to close, including Darlington. They had just completed construction on their latest batch of Class 08 shunters ending with D4185. Once the Type 2 orders were completed, the steam repairs finished & the diesel repairs transferred away there were expected to be layoffs totalling 1,700 jobs. The only temporary relief came with the knowledge that the diesel repairs would last for several more years, particularly in the light of the heavy workloads of Derby & Crewe.
As mentioned earlier D5176 featured the new AEI 253AY traction motor, the motors were a result of the collaboration between BTH, MV and American builder Alco. This smaller, lighter motor was an attempt to market a traction motor to a worldwide audience, especially to the meter gauge lines. For the Class 25 these lighter motors allowed the discontinuance of other weight saving measures being built into the design. Under the Class 25 they would be highly rated, being an attempt to overcome the loss of tractive effort normally found on starting, the field divert system was also modified to allow increased capability throughout all the speed ranges. For the technically minded the rating on the generator changed to 735kW, 780/545V, 1050/1500A at 750 rpm with the smaller traction motors now in series parallel being rated at 234hp, 315V, 650A at 460rpm, with a gear ratio 18:79. Maximum tractive effort was 45,000lb with full power now available between 7 and 77.5 mph, an improvement over the Class 25/0's, all other ratings were unchanged from the D5151 series. The continuous rating of 650 amps was not far removed from its one hour short term or 'emergency' rating of 680 amps, which could only be monitored manually. On heavy trains close monitoring of the ammeters was necessary to avoid motor damage. Fuel capacity was now 560 gallons (loco weight 71.75 tons). For those with boilers, water capacity was 580 gallons (loco weight 73.75 tons). Whilst the body shell remained similar to D5151 there were a number of refinements. Relocated were the air horns to either side of the headcode panel. The cab skirt and body fairing were discontinued, though the support lugs remained. A new driving control panel was fitted. The fuel & water tanks were also redesigned.
Another less obvious external change was the relocation of the engine exhaust. In the Class 24 & Class 25/0 the exhaust was routed from the engine through silencer boxes and exhausted to the atmosphere through a circular port located in the boiler room roof. This arrangement led to a number of fires and explosions following the ignition of oil laden vapours in this space. Subsequently a design modification saw D5176 - D5232 & D7568 - D7597 have the exhaust vent through a rectangular port above the turbocharger. Subsequent builds from D5233 onwards saw the exhaust arrangement revert to the original Class 24 design.
The first seven Class 25/1s were allocated to North Eastern Region depots; D5176 - D5178 (boiler equipped) to Holbeck (55A) whilst D5179 - D5182 (non-boilered) were allocated to Gateshead.
For the locomotives based at Holbeck passenger work was the order of the day, both local and longer workings as D5178 was so provided on February 14th for a run to Morecambe only six days fresh out of Darlington. By this time the vast majority of the Leeds local services were in the hands of diesel multiple units. As the diesel and multiple unit fleets grew so the impact on steam workings escalated. Typical was the closure of Scarborough shed on May 18th, the two diagrammed steam freight workings turned over to D5096/8/9 & D5100/76 the following Monday, Gateshead based D5178 worked that first turn on May 20th. Station pilot duties were managed by two Class 03s. On May 28th the first turn, the 04.30am York - Scarborough led by D5100 had 77004 as pilot, destined for the Malton - Whitby freight. However cinders from the ashpan set alight to the diesel necessitating the service of the Malton Fire Brigade. The service resumed behind 77004, the diagram later being taken over by D5099 which later failed on the last leg of the run, at Rillington on the 07:49pm Scarborough - York mail. Rescue came in the form 43014. All was well by the Whitsun weekend, June 2nd, when seventeen specials worked into Scarborough, the Sulzer 2s handling two, led by D5099 and D5176. On June 8th D5176 was noted southbound through Sheffield Midland with an excursion train.
An early passenger working observation of D5176 took place on June 8th 1963 being noted at Sheffield Midland on an unidentified excursion.
During June Holbeck lost its three passenger Type 2s, which included D5176 being transferred to York (50A).
During February energisation of the overhead took place from Garstang to Carlisle. Diesel powered test trains operated between Preston & Carlisle, various test vehicles and vans were used, including 5285 (March 4th), 25026 (March 11th) & 25035 (March 21st).
25026 moved to Tinsley in August and visited Derby Works during August. During this Works visit the cab front gangway doors were sheeted over and the locomotive received a full repaint. The Open Day at Barrow Hill on September 22nd 1974 included 25026 in the roundhouse.
On October 31st 25026 worked the 8B40 Whitemoor - Hitchin (via Royston not ECML).
A long distance working, the Leith - Salisbury pipes featured the Scottish Type 2's working as far as Didcot, examples noted were 25011 & 25026 on March 13th & 15th and 25026 & 25092 on April 24th, the locomotives later noted heading northbound behind 47107. On June 4th 25026 & 25101 were noted at Oxford with 25026 being stopped for repairs. In general the pipe train locomotives returned to the Birmingham area light engines.
The 15.52 Glasgow Queen Street - Aberdeen was worked by 25026 & 25033 on July 9th 1976. On August 19th 1976 25026 & 25035 were noted at Oxford on the pipe train to Yeovil. The 21.40 Edinburgh - Carstairs was worked by 25026 on September 2nd 1976.
The 20.10 Perth - Edinburgh on July 25th 1977 was worked by 25026 & 25065. An Inverness - Birmingham relief to the 'Clansman' on August 27th was worked by 25026 & 25066 to Mossend.
25026 was noted at Glasgow Works at the end of March and for much of April for its last major repair and repaint. A very ex-works 25026 was noted with 27033 on a passenger working at Dundee on June 3rd, presumably under test from Glasgow Works.
After release from Glasgow Works the summer months saw regular passenger service for 25026, including the Edinburgh - Carstairs services and the Glasgow/Edinburgh - Dundee services.
25026 was noted on Haymarket shed for most of August 15th.
A busy couple of days in the middle of September started with the 21.40 Edinburgh - Carstairs on September 13th, two days later (15th) the 15.58 Dundee - Glasgow Queen Street was worked by 25026. On September 16th the 06.40 Glasgow Queen Street - Dundee, the 14.44 Glasgow Queen Street - Dundee and a return Dundee - Glasgow Queen Street were worked.
On November 13th 25026 worked the 10.44 Glasgow Queen Street - Dundee and the 13.39 Dundee - Glasgow Queen Street.
And finally for 1978 on December 5th the 21.40 Edinburgh - Carstairs was worked.
An adventurous weekend trip from Ealing Broadway to Aberdeen/Inverness March 16th - 18th proved too ambitious as it was curtailed at Aberdeen running over seven hours late, mostly caused by bad weather. The outward leg was taken over at Mossend by 27016 & 25079 to Aberdeen, the return from here featured 25026 & 25068. This pair were also noted on the 12.35 Aberdeen - Edinburgh on March 27th.
On April 21st 1979 an early afternoon Edinburgh - Perth service was hauled by 25026.
On June 16th 1979 25026 and a weedkiller train were noted at Portobello off the Leith branch.
A typical Scottish working for 25026 occurred on September 25th when it worked the 22.25 Edinburgh - Dundee. And on October 10th 1979 25026 worked the 21.40 Edinburgh - Carstairs.
25026 was stabled at Perth on April 5th - 7th. On April 16th 25026 worked a short Leith - Portobello freightliner feeder service, then was procured by the Freightliner depot to handle some more substantial shunting manouevres. 25026 was stabled at Millerhill on April 24th & 25th.
On May 21st 1980 an Inverness - Aberdeen service was worked by 25026.
25026 & 25066 were stabled together at Aberdeen Ferryhill on June 9th. 25006 & 25026 were noted westbound at Edinburgh Waverley on June 15th with passenger stock.
On July 5th 1980 the summer dated 15.15 Scarborough - Glasgow Queen Street was worked forward from Edinburgh by 25026, the next day (6th) 25026 was stabled at Haymarket. The middle of July included the 21st's 21.40 Edinburgh - Carstairs, the 23rd's 06.35 Carstairs - Edinburgh, the 24th's 07.40 Edinburgh - Glasgow Queen Street followed by the 17.10 Glasgow Queen Street - Edinburgh and the 26th's 06.35 Carstairs - Edinburgh. The evening of July 28th found 25026 stabled at Millerhill.
The month of August produced the 9th's 23.15 Kings Cross - Aberdeen forward from Edinburgh with 25026 & 25066, the same pair with the 11th's 09.50 Aberdeen - Glasgow Queen Street and 25026 by itself on the 20th's 17.10 Glasgow Queen Street - Edinburgh. The last recorded passenger working for 25026 took place on September 13th 1980 with 25023 working the Dundee - Edinburgh portion of the 'Tyne-Tay Express' railtour return leg, following the failure of A4 Pacific 60009 'Union Of South Africa'. The next day (14th) 25026 was stabled at Millerhill.
On the afternoon of September 21st 25026 was stabled at Millerhill.
At the start of the winter timetable the Scottish Region sent eight Class 25s to the London Midland Region and withdrew five more. The LMR itself condemned seventeen machines and placed six into storage. To cover some of these moves Inverness sent four Class 26s to Haymarket; Immingham sent two Class 37s to Eastfield and three Western Region Class 37s were moved to Laira. The movement of the Class 37s to Eastfield would allow the Class 27s to be replaced on the Oban/Mallaig services. One of these transfers was of course 25026's move from Haymarket to Toton, where it did not remain long in service, on November 2nd it was withdrawn.
