Notes

These small engines were also ordered for the Great Northern Railway at a cost of £1,690 each. Their diminutive size made their usefulness doubtful; however they apparently ran reasonable mileages before the arrival of B13 engines. They could haul 45 tons on easily grades sections of the GNR but only 15 tons up the old Mingela Range route.

Both were eventually transferred to the Bowen Railway. After N°177 was written off, its boiler was used for a time at a pumping plant at Torrens Creek.

In 1889 locomotives and rollingstock were consolidated into one rollingstock register. This resulted in most items, except those operating on the original Southern and Western Railway (from Ipswich ), being renumbered. Numbers shown are state (or former S & W) numbers. Those in brackets are former numbers of individual railways.
