These twin locomotives have had a remarkably similar career. They were built at Swindon Works in 1958, becoming Nos. D2023 and D2024 respectively. The design is similar to class 04 which were used on the line during the final years of the BR freight service.

These two locomotives were both withdrawn from Lincoln in July 1971 and a year later became Tees & Hartlepool Port Authority (Middlesborough Docks) Nos. 4 and 5. They were transferred to Grangetown in 1980 and sold to the K&ESR in 1983, arriving on 14 August (No. 47) and 4 September (No. 46).

No. 47 has yet to enter traffic but No. 46 quickly received a major overhaul and was fitted with vacuum brake equipment. It re-entered service in Brunswick green livery,and although in black for some time was repainted green in 2006. It has taken an active part in operating the railway 'but is only used as a standby engine for Dover Castle.
