October saw Derby Locomotive Works lay down the frames for D7598, the first of order N10001. These machines would later be designated Class 25/3, a total of eighty would eventually be built. They still carried the RTB 15656 generator, now a ten pole machine with a modified assembly that was now incompatible with earlier equipment. The latter half of the 1960's had seen the widespread introduction of solid state electronics with transistors making such equipment accessible and affordable to increasing sectors of industry. Thus these machines were to incorporate an infant electronic control system, whereby speed was detected electronically rather than mechanically. This was then used to activate the field weakening process in the motors, rather than through contacts and relays as in earlier types. Maximum tractive effort was adjusted to 41,500 lb allowing maximum speed between 7 and 80 mph. Only two stages of field weakening were employed, previous machines employed six fields, these were later reduced to two. Mixing of the main generators between class 25/0 & 25/3 was not allowed.

D7598 was constructed at Derby Works during the winter of 1965/66, part of a batch of thirteen machines (D7598 - 7610) destined for Tinsley (41A), all were released to traffic during February 1966.

With D7598 allocated to Tinsley some of the Sheffield area summer dated services were diagrammed. On July 9th D7598 worked a Sheffield - Chinley local. A week later (16th) the 09.28 Sheffield - Llandudno Town and the return 14.28 Llandudno Town - Sheffield were worked by D7598. On September 3rd D7598 again handled the 09.28 Sheffield - Llandudno Town and the return 14.28 Llandudno Town - Sheffield. The next day (4th) D7598 was noted at Rhyl presumably with an excursion from the Sheffield area.

In September the Scottish Region swapped D7598 - 7601/11/12 for D7576 - 79/81/83/84, the latter being boiler equipped, allowing them to replace the ailing NBL types on the Glasgow - Dundee run, with D7598 & D7599 moving to the Midland Lines. D7598 was then immediately transferred to the Birmingham Division (D02).

On May 15th D7598 with a brake tender worked the 8V70 Banbury - High Wycombe and the balancing return working, this was normally diagrammed for a Western Region hydraulic.

A portrait of 25248 at Preston on August 27th 1982. The paint job and number position suggests 25248's last Works repair was carried out at Crewe Works, probably in the mid 1970's. This is the last summer in service for 25248, within a few months it will be withdrawn.
