facilitate construction of the Eastern Suburbs Railway, a new line was constructed down Elizabeth Street between Devonshire Street and Redfern Street and the route was deviated to run down this new section. The line was electrified double track throughout. The line was closed in 1957. Waterloo Wetlands The Waterloo Wetlands once dominated the landscape of the surrounding areas of Waterloo and Zetland. Woolwash Park Pond is the only remnant of this landscape which connected to a vast aquifer that still runs below the site. In the 1800s industries such as wool washing and tanning were attracted to this area by the clean water from the aquifer. Vegetation remains. Woolwash Park Pond is an important part of the innovative water management and irrigation system at Victoria Park, Zetland. Because the pond is used for irrigation, fish and aquatic plants are banned from the pond. Population At the 2021 census, the suburb of Zetland recorded a population of 12,622.
