Almost brand new D7521 at an unknown location with an inter-regional passenger working. The photograph clearly shows the original location of the engine exhaust port, circular in shape and close to the boiler room.

Condition April: two-tone green livery with small yellow warning panels, no blanking plates, hand/footholds present, straight sided sandboxes, three rung bogie mounted footsteps, engine exhaust in original location, bufferbeam mounted steam pipe connection present.

On the ex-Great Central line at Blackwell (MP61) by the LMR boundary 7504 & 7521 were noted on track lifting trains the week following closure. Authorities were anxious to remove the re-useable rail prior to the right of way being severed by the construction of the M1 motorway.

On July 23rd the summer dated roundtrip Nottingham - Llandudno Town was worked by D7521 & D7502

The Toton Open Day on May 30th 1970 featured 7521 and the Toton 75 ton crane demonstrating the art of how to rerail a locomotive.

Condition May: two-tone green livery with full yellow ends, no blanking plates fitted.

On June 24th 7521 & 7522 worked the Derby - Norwich - Yarmouth - Norwich - Walsall passenger diagram.

On December 9th (a Sunday) eight additional freights ran from Margam to Knighton & Toton, three powered by Class 37s, the remainder by Western Region allocated Class 25s. All worked as far as Washwood Heath, returning to the west as light engines or with a freight train. The Class 25s involved were 5209, 7508, 7510, 7513 & 7521.

On April 20th 7520 & 7521 were noted passing Newport High Street with up hoppers.

On December 30th the 17.20 Edinburgh - Dundee was formed of locomotive hauled stock with 25171.

On the afternoon of August 15th 25171 was noted with a northbound freight at Perth. The last recorded passenger working for 25171 was about a month before its demise, on August 23rd 25171 worked the 06.57 Dundee - Glasgow Queen Street.

September 22nd turned out to be the final day for 25171. Whilst hauling a ten wagon ballast train southbound at Arbroath the train ran out of control and was diverted into the goods yard since both main lines were occupied. It demolished the buffer stops and impacted the retaining wall causing major structural damage to the locomotive, not helped by two of the now derailed ballast wagons demolishing the rear of 25171. The guard and driverís assistant jumped to safety, the driver taking refuge in the engine room.

The No.2 end was leading, with the cab being crushed, the leading bogie was derailed. The No.1 cab was pushed upwards and crushed after being hit by the leading bogie ballast wagon, the second ballast wagon had slid under the leading wagon and been crushed. It is reported the engine was still idling after the collision had occurred.

Condition Final: blue/yellow livery, blanking plates fitted, hand/footholds plated over, three-rung bogie mounted footsteps, sandbox styles appear mixed.

During November 2016 a builder's plate from 25171 sold for GBP395.00 on ebay.
