The C35 class (originally NN) was a class of steam locomotives operated by the New South Wales Government Railways in Australia. They were built with the 4-6-0 wheel arrangement at the NSWGR Eveleigh Workshops from 1914 to 1918. A total of 35 were made. All were fitted with superheaters and with exhaust steam injectors when built.

Despite their elegant, somewhat English-looking appearance as built, they suffered a long period of teething troubles and were rather poor performers, especially on long climbs.

They took over hauling The Fish, from Sydney's Central to Mount Victoria in June, 1918 and the Caves Express on the same route in 1932. To mark this, 3506, 3526 and 3535 were painted in Caledonian Blue to match the new carriages made for the express.

3508 was experimentally fitted with an ACFI feedwater heater in May, 1935. It was apparently not a success as it was removed in 1939 and no other member was so fitted.

From December, 1937, the class was rebuilt with heavier frames, rebalanced driving wheels and given new cabs with more shelter, replacing their "Great Western Railway" look. During the last years of service, they were confined to working trains north of Gosford. The last members of the class were withdrawn in July, 1968.

The C36 class are a further development of the C35 class.[1]
