gearbox fitted. Although there is still some tinkering to be done, this addition has greatly improved the locomotives haulage. The locomotive is not in regular use because of its insufficient haulage capacity and not having the required horsepower to climb the grade before Middleton station. Engine: 3½ HP Villiers Mk25 with reduction box Transmission: Cup and cone reversing clutch and chain drive Claytons The railway has three battery Claytons of similar designs in private ownership. L10 (works Order No. 5431 of January 1968) and L16 (W/O No. B0109B of March 1973, named Peggy) are , low-height locomotives. They were both bought directly from industrial use. Peggy has recently been restored to operating condition, and is running using the redundant 15-year-old batteries from Greenbat. Peggy is fitted with a cam-contactor controller and resistances for speed control. Peggy serves as the primary locomotive for work trains on the SGLR, taking volunteers up and down the line to do rail and infrastructure maintenance, often seen with the tool wagon being shunted back and forth. Peggy also works on the branchline trains down into the quarry, interchanging with Peter every so often. Lady Margorie is a compact , Clayton. Designed to work in diameter sewer pipes, she even has a "barn roof" style battery box top to make maximum use of confined space. She has an electronic controller, as opposed to the more usual resistance type. On 20 May 2012 Lady Margorie was renamed Peter after the late Peter Sellers, the society chairman. Ladywash Mine No.6 This was the first locomotive on the railway, bought with a large amount of track and rolling stock from Ladywash Mine, near Eyam in Derbyshire. She is a , design also from Greenwood and Batley. She spent all her working life at Ladywash, acquiring some interesting but highly useful modifications – her works photo appears in Adrian Booth's book on Greenwood and Batley, and is quite interesting to contrast with her current form. She was also fitted with a thyristor controller, which was removed before being sold. She arrived at the SGLR in a poor state of repair which, along with the lack of controller, meant she was dumped around various sidings untouched. Eventually she was bought in 2004, and work finally started on her restoration. Following removal from the site for shotblasting, the frames have been repainted and simultaneously the axleboxes overhauled. Now back on site, she
