Neilson Reid and Ashford Works delivered the first two. From 1900 to 1909, the railway works built the majority, with Ashford producing a total of 69 and Longhedge another 9. Neilson Reid contributed 14 and Sharp, Stewart added 15.

"The possibilities of economical and efficient locomotive conversion are well exemplified" by this makeover of the592 of Wainwright's numerous C class goods locomotives (Locobase 5203). The railway's own shops turned out their first saddle tank, fitting it with a larger and "remarkably commodious" cab and installing a bunker and side tanks. Successful development of the Stirling steam reverser for the C class meant that Ashford made a special effort to retain it on this shunter. LM noted in explanation that "power mechanism for reversing is particularly useful in shunting engines on account of the frequency with which this operation is performed." 685 was the only such conversion, but the railway got its money's worth. 685 contributed to Britain's World War One effort as the shunter at a secretly built "Q" port in Kent. According to the SEMG, the military dug a tunnel under Roman-built Richborough "fortress" to connect the newly dredged port on the River Stour with the SE&CR mainline. "Vast amounts of military equipment - including locomotives - and arms were sent across from Richborough Port," says SEMG. They used "sea going barges and the very first roll-on roll-off ferries." War's end saw the engine go to work at the Bricklayer's Arms railroad station in Central London. It was finally withdrawn by British Railways in 1951.
