For the new interstate train 'Southern Aurora' in 1962, two deluxe twinette sleeping cars were built in 1961. They were built in October 1961 and were ready for the first run March 1962.
There were two cars: DAM 2333 and DAM 2334.
By 1991 the cars were out of service. DAM 2333 was sold to the ARHS(Vic Division) in 1994 and DAM 2334 was sold to a buyer in NSW.
