The LSWR C8 class was the first class of 4-4-0 express steam locomotives designed by Dugald Drummond for the London and South Western Railway and introduced in 1898.
According to Dendy Marshall[1] they "were of orthodox design, very much like engines which Drummond had put on the Caledonian".
H.C. Casserley states that they were very similar to the Caledonian Railway 66 class.
[2] They used a similar boiler to the Drummond M7 0-4-4T and 700 class 0-6-0 engines built for the LSWR.
291 worked a train carrying the Grand Duke and Duchess Serge of Russia from Windsor through to Dover on the LCDR.
