 This last batch had cabs with steel cutaway sides, an improvement on the open cabs of the earlier batches.In the late 1880s the class were based at Sydney, Goulburn, Penrith, Bathurst, Newcastle, Murrurundi and Armidale.From February 1901, all of the class were fitted with larger Belpaire boilers which increased their weight and also increased the heating surface, matters identified as deficient in William Thow's Report of 1889.
