Notes

These small engines were ordered for the Great Northern Railway. When they arrived from America it was considered that the Southern & Western Railway had a greater need and so they never reached their intended destination. They were tiny machines with only four wheeled tenders. One was used in the Ipswich district and the other was put to use on the Main Range where its load was only 75 tons.

N° 42 was transferred to Bundaberg Railway in 1882 where it became (second) N°1. In 1900, it was sold to Gibson & Howes and continued to work at Bingera Mill until 1946. Eventually N° 43 was considered too small to be useful and was withdrawn from service in 1899 but was not written off until 1902.

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.

The 422 class, purchased by QR National/Interail from Northern Rivers Railroad, were originally built in 1969 for SRA (and then Freightcorp) by Clyde Engineering at Granville. The locos are of a full body dual cab design and have use the EMD16-645E power plant (which effectively makes them an updated version of the 421s). The 422s have operated across Australia after a number were purchased by Australian Southern Railroad (ASR) in the period 2000-2005. Refurbished and renumbered to the 22 class, most notably were 2201-2204 which were used on the construction of the Alice Springs to Darwin line. In 2006, QRNational owns 18 members of the class, including 42202 and 42206 (ex-Interail); along with the 16 members of the 22 class (some renumbered, some are not).
