an NSW Class Z20 steamer on the Carlingford branch line

No date. The Z20 was a class of 33 (19 new, 14 rebuilt from Z19 class) 2-6-4T from the 1890s.

The Carlingford railway line was a 7 km branch in Sydney. It was opened from Clyde to Subiaco (later renamed Camellia) in January 1885, then by means of the construction of a bridge across the Parramatta River, to Carlingford in April 1896. It closed on 5 January 2020 with much of the line to be converted to light rail as part of the Parramatta Light Rail network, while a short section of the line was retained for use by Sydney Trains.
