Mixed-traffic engine with relatively high drivers. According to OS Nock (RWC I, pl 181), JE McConnell, then locomotive superintendent of the London & North Western, was a consultant to the Sydney Railway Company. When the Sydney ordered four engines, McConnell's Wolverton Goods 0-6-0 design, then just under construction, stood in, although only the first two axles were driven and the rearmost wheel diameter was reduced.
According to the Powerhouse museum website ([], visited 11 April 2004), the official opening came on 26 Sept 1855. In that first day, 3,554 passengers were hauled on the 14-mile , 50-minute trip.
After their delivery in 1855, the 4 engines were widely praised and showed well with their brass domes and smokeboxes. "The only trouble with them," Nock comments, "was that they were far more powerful than the Australian railway needed ...For some time afterwards, locomotives built for the New South Wales were of rather lighter design." By 1857, # 1 had been moved to freight service, in which it operated for 20 years, compiling altogether 155,667 miles (250, 468 km)

The tube heating surface area as derived from tube length, count, and diameter is significantly higher than that offered in the databook table. Tubes of 1 1/2" in inside diameter could generate the given figure.

Slightly larger than the 1 class, this too was a mixed-traffic engine with relatively high drivers.All were built in Australia. Four came from Mort's Dock (the first drydock to open in Australia) and four from Eveleigh Railway Workshops, the NSWGR's main construction and maintenance facility that opened in 1878.
