Withdrawal
The very first Class 24 to be withdrawn was in November 1967 when a fire broke out on D5051 while it was working a train of empty coal wagons in Scotland.
The damage was too severe for it to be repaired, and it was cut up at Inverurie in August 1968.
It had lasted exactly 8 years.
The second Class 24 to be withdrawn was also as the result of an accident in Scotland, this time at Castlecary.
In this case D5122, running light engine, hit a stationary DMU at about 40 mph (64 km/h), the impact and subsequent fire bending the main frames and completely destroying the No.2 end.
The accident happened on 9 September 1968 but despite being withdrawn the same month, the locomotive was not finally cut up until March 1971.
A total of fourteen Class 24s were withdrawn and scrapped without receiving a TOPS number.
Some Class 24s were withdrawn in 1973 with the closure of the Waverley route, which linked Carlisle and Edinburgh, but most of these were put into storage and subsequently re-entered traffic to fill gaps left by the movement of Class 25s to cover the withdrawal of Class 22s on the Western Region.
Thus Class 24 withdrawals only started in earnest with completion of the Glasgow electrification in 1974, and re-allocation of Class 26 and Class 27 locos saw the Class 24s concentrated around various Lancashire depots and at Carlisle.
On 27 November 1976 there were just ten Class 24s still in operational service, all allocated to Crewe Diesel Depot (depot code CD).
However, with the reinstatement of 24082 and 24073 this number climbed to 12 by February 1977.
In January 1978, two farewell rail tours were run – 24082 and 24087 hauled the
Merseyside Express from London St Pancras to Liverpool and return on the 14th, and 24087 and 24133 hauled the
Cambrian Coast Express from Birmingham to Aberystwyth and Barmouth on the 28th.
On the latter trip, 24087 failed on the outward journey, was dumped at Machynlleth on the return journey and never worked again.
On 21 January 24133 had also taken part in the "Farewell to the 44s" tour, providing steam heating for the coaches while 44008 Penyghent provided the motive power, on the Crewe to Chester leg of a circular tour from London.
For the summer of 1978, six class 24s remained in service – 24023, 035, 047, 063, 081 and 082.
In May, a North Wales DMU passenger diagram was converted to loco haulage on Mondays to Fridays.
At least five different class 24s were recorded on this diagram during the summer.
Additionally, on Saturday 10 June 24082 worked a Llandudno Junction – London Euston relief train all the way to London due to a lack of a replacement loco at Crewe.
By January 1979, only three locos remained in use – 24063, 081 and 082.
24082 was withdrawn on 1 March and 24063 on 9 April, leaving 24081 the last in service.
The final recorded passenger duty of a Class 24 was on 2 August 1979 when 24081 rescued 40129 at Colwyn Bay on the 18:05 Holyhead – Euston, hauling the train as far as Crewe.
Cutting up of some Class 24s was carried out at Swindon Works on the Western Region, an area which had never received an allocation of Class 24s.
The first locos were 24042, 24045, 24048 and 24050 which were moved from Derby Works in December 1975, and the last of the 67 Class 24s cut up at Swindon was 24084 in early December 1978.
The very last Class 24 to be withdrawn from operational service was 24081.
This loco, allocated to Crewe Diesel Depot had been considered something of a celebrity, lasting over a year after the previous withdrawal of 24063 on 9 April 1979.
24081 was finally withdrawn in October 1980 having worked its last revenue earning train, the 05.43 Grange - Shotwick freight on 7 January 1980, and then making guest appearances at Nuneaton, Crewe Works Open Day, and Southport.
