LSWR O2 class
Construction history
The second of William Adam's 0-4-4 designs, the O2 Class was a development of his previous T1 class of 1888. The brief behind the design was to create a locomotive capable of mixed-traffic operations, a characteristic dictated by the relatively small wheel diameter and smaller cylinders, effectively to replace the obsolete Beattie Well Tank.
