Remarks:    The second batch of locomotives ordered from Naysmith, Wilson in 1883 consisted of ten 2-8-0 freight engines. Like the previous "V" class, they were overweight and had to be considerably modified. They were rather odd looking engines with the cylinders set forward from a rather stubby boiler and beyond them projected the main frames and the leading pony truck. Generally they were good performing locomotives, well suited to the 20 m.p.h. freight haulage and on level track could stagger along with loads of up to 1000 tons.
