The fifteen year eight month career of D5099/24099 was split between North Eastern Region and Scottish Region depots.
Built BR Darlington Works (batch D5094 - D5113).
The frames for D5099 were laid down at Darlington Works during December 1959, D5099 was new to Gateshead (52A) on June 3rd 1960. Further transfers were:
February 1963 to York (50A).
Renumbered May 1974.
After withdrawal 24099 was stored at Eastfield from August to October 1975, then at Carstairs from October 1975 until April 3rd 1976 when it was forwarded to Doncaster depot. It remained there until September 1976 when it was moved over to Doncaster Works and broken up by July 1977.
Works visits (records incomplete).
Noted Darlington Works August & September 1960.
Neville Hill diesel depot was officially opened on June 17th. Although principally servicing diesel multiple units, diesel locomotive servicing was provided, on display on the opening day were D278 & D5099.
The North Eastern Region Type 2s had returned to handling the Newcastle - York - Leeds services, D5097 on 7.30am Leeds - Newcastle and 11.05am return (July 9th) and D5099 on 11.40am Leeds - Newcastle and 5.33pm return (July 9th).
As the diesel locomotive and diesel 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 & 5100/76 the following Monday. 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.
D5099 was noted in Darlington Works during in October.
On Sunday March 7th noted on York shed were D5096, D5098, D5099, D5100 & D5239.

On August 29th 5098 & 5099 (both in blue livery) worked a twelve coach mystery excursion from the Whitehaven area to Cleethorpes, running via Carnforth, Skipton, Leeds avoiding line and the Doncaster avoiding line. It is presumed the Class 24s worked throughout.
A re-shuffling of the fleet took place to bring to an end the few remaining NBL & Claytons locomotives on the Scottish Region. Part of this plan involved Type 2s from Gateshead & Holbeck, 5099, 5100/101 moved to Polmadie (66A) in July, whilst 5096/97/98 followed in October.

The major fleet rationalisation that took place during the summer of 1975 saw 24099 placed into store during August, then withdrawn during February 1976.
