The Z29 class (formerly J.483 class) was a class of steam locomotives built for the New South Wales Government Railways in Australia. They were used principally for goods transport up the steep gradients of rail track in the Blue Mountains, but also served on the Main South as far as Junee, the South Coast line as far as Waterfall and on Western lines as far as Mudgee and Wellington. Their introduction required cutting back some platforms as well as flattening their cylinder sides to achieve clearances. Over the years they lost some of their distinctive Baldwin appearance with reboilering with Belpaire boilers and acquisition of standard NSWGR chimneys and smokeboxes. The last two members of the class (501 and 502) were delivered as 4 cylinder Vauclain compounds. The last withdrawn was 500 (by then 2918) in April 1935, scrapped at Chullora in November 1937.^[2]^[3]^[4]^[5]
