These engines were referred to as Large Consolations before the introduction of the new classification system.
They were the first eight coupled engines to run in Queensland and were also the first to have a bogie tenders. An early problem experienced with them was that they were too long for existing turntables and could only be turned on fork lines. They were built by Baldwin and were typical of that company’s products of the time with a large oil headlight, pepper pot steam dome and sandbox and also a wooden cab with glazed windows.
N° 41 was put to good use on the Main Range where it could haul 120 tons compared with 75 tons for the E (B12) Class although it had originally been purchased with the intention of being used on the line beyond Chinchilla. It was shipped to Townsville in June 1881 and was later returned to Ipswich in 1890.
N°42 was imported by the contractors working on the Stanthorpe Extension and named “Queenslander”. It was later bought by the railway after the new line opened in May 1881.
The engines had their original wagon top boilers replaced with round top ones in 1900. Apparently engine loads were not increased even though the new boilers had an increased pressure of 140 psi.
Both finished their days working in the Rockhampton District.
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.
