Immediately following the Stephenson-built Moguls (Class 6), these Sharpies had a slightly bigger boiler and a much bigger grate. The boiler was also higher. Over time, the locomotives were fitted with 3-axle tenders with more water capacity. Taken into the NSB as Class 44 in 1926, the last was retired on 10 November 1954.
