Purchased as two four-wheel carriages in 1873 from the Metropolitan Carriage & Wagon Co., Ltd., of Saltley Works in Birmingham and later allocated fleet numbers A.8 and C.8, by 1881 these two carriages had become close coupled and were later mnounted on a new steel underframe, again supplied by the Metropolitan Carriage & Wagon Co., Ltd., in 1924 to become F.56.  The carriage in this form survived in service and was latterly demoted to schools train work only, retaining the all-over brown livery.  It has been scrapped.
