33108 is a BR Class 33 locomotive, owned by the Class 33/1 Preservation Company Ltd. 33018 33108 first visited the SVR for the 2012 Diesel Gala, and again attended the Spring Diesel Festival in 2017. Following the latter, it has remained at the SVR for an extended stay, initially until at least May 2018 and later further extended<ref name="MeetTheLoco">[http://www.svr.co.uk/MeetTheLoco.aspx?id=90 SVR - Operational & non-operational diesel locomotives], accessed 14 January 2018</ref>. The Southern Region of British Railways ordered 104 locomotives from Birmingham Railway Carriage and Wagon Company (BRCW) of Smethick, Birmingham (works numbers DEL 92-156, DEL 169-189 and DEL 157-168). The last 12 locomotives were 7 inches narrower, to enable working through the restricted tunnels of the Hastings line. All were delivered between 1960 and 1962 in standard BR loco green, most being repainted BR blue during the late 1960s and early 1970s. The locomotives were of a new design, based on the BRCW Type 2 (later Class 26), with a larger engine. They are powered by a Sulzer 8 cylinder in-line engine of 1,550 bhp, designated 8LDA. The main generator and the four traction motors were supplied by Crompton Parkinson, hence the class's 'Crompton' nickname. The class worked all kinds of duties on the Southern Region including passenger trains, for whey were the first BR diesel locomotives to have electric train heating. During 1967, 19 of the locomotives were fitted with push-pull equipment to enable them to haul 4-TC units on the unelectrified section from Bournemouth to Weymouth, and to carry warning lights and klaxons for boat trains on the road section of the Quay.<ref>[http://www.class33crompton.co.uk/CromptonHistory.htm Cromptons' history, BR Class 33 website] (Retrieved 12 September 2020)</ref> In the TOPS renumbering these were designated Class 33/1 and the Hastings line 'Slim Jims' Class 33/2. Electrification was extended to Weymouth in 1988 and the 33/1 sub-class displaced to wider duties.

 D6521 was constructed at BRCW to works No. DEL113. It entered service at Hither Green in September 1960,and was reallocated to Eastleigh in 1963, where it remained for the rest of its working life.<ref name="Crompton33108">[http://www.class33crompton.co.uk/Crompton33108.htm Cromptons - BR Class 33 Locomotives - 33108], accessed 20 November 2017</ref> and During 1967 it was reallocated to Eastleigh in 1963, where it remained for one of the rest of its working life. It locomotives fitted with push-pull equipment and so was renumbered 33108 on 1 January 1974.<ref name="Class33PresCo">[https://preserved3310833111.wordpress.com/home-page/history-of-33108/ Class 33/1 Preservation Company - History of 33108 (D6521)], accessed 20 November 2017</ref> The locomotive ended its life as depot shunter at Eastleigh, and remained in working order until withdrawn on 24 May 1993, being sold to the Class 33/1 Preservation Company in January 1997.<ref name="Class33PresCo" />
