Locomotive 3526 is a two-cylinder, simple, non-condensing, coal-fired superheated, 4-6-0 New South Wales C35 class locomotive express passenger steam locomotive. The only C35 class left in existence, and is operational. The class is commonly referred to as "Nannies" or "Naughty Nannies" due to their Pre-1924 class designation of NN.


3526 was built by the NSWGR's Eveleigh Workshops. The loco was completed in March 1917. It was works number 118.

In service[edit]

On entering service as one of the 35 members of the NN Class. It was allocated road number 1314. 3526 was one of only three engines specially painted in 'Caves Express' colours in the early 1930s, the other two were 3506 and 3535.Throughout its service life, it received the various modifications made to the class, and was rebuilt with new frames and cab in July 1940 when the class suffered from frame cracking. After the loco's rebuild, 3526 was one of many to receive a lined green paint scheme.

Demise and Preservation[edit]

During 1964, 3526 received a tender from a scrapped standard goods loco to replace the original because of limited coal and water capacity. A few other members of the class also received these tenders too. 3526 was withdrawn from service in 1967 and was retained for preservation, allocated to the NSW Rail Transport Museum where it remained operational until 1974. On preservation in 1967 the loco once again received an original type C35 class tender, Tab No. 1309, which came from locomotive 3519.[1] The loco was repainted in a deep blue intended to represent 'Caves Express' colours - initially with heavy white lining, and from 1971 with gold (yellow) lining.[2] With the transfer of the Museum from Enfield to Thirlmere in June 1975, it traveled to Thirlmere under power. It did not steam again until 2004.[3]


In 1983 the boiler clothing was removed for assessment of the boiler, and in 1990 restoration to operation began in earnest. During 1990, a spare 35-class boiler number 3504C was also retrieved from static use at the old Eveleigh workshops and is now stored at the NSWRTM. Completion of the restoration was achieved in early 2004 after a government grant for new boiler tubes. The previous deep blue livery was replaced by unlined black to reflect the locomotive's appearance in later years of its service life. As noted above, 3526 did not carry Caves Express colours in regular service in its current, rebuilt form with new frames and cab: in this form it carried first lined green and then unlined black.

As at April 2015 3526 was undergoing an overhaul announced in July 2014 [4]
