A clock tower has also existed at the end of Elizabeth Street since 1883. The first clock was known as the 'Water Tower Clock', after a wooden framed water tower erected on the site in 1853. This clock remained in place until 1905 when work begun on the new station, the clock tower being moved to outside Princes Bridge station. In 1911 it was moved to Spencer Street station, where it remained until the station was redeveloped in 1967. Sold to a private collector, it was returned to public ownership and in 1999 was put on display at the Scienceworks Museum, Spotswood. It was returned to the renamed Southern Cross station in 2014.
