Early industries in the area included C & W Sheil's brickworks, which had quarries in Forbury, St Clair and Caversham, and Caversham Gasworks, which operated from 1882 until 1909. The last buildings of the gasworks were a local landmark, and were not removed until the construction of the Caversham bypass in the 1970s and 1980s. Other noted industries in early Caversham included breweries, a tannery, and a match factory.Construction of the South Island Main Trunk railway south of Dunedin that began in 1871 led to the construction of a 865-metre (2,838 ft) tunnel beneath Lookout Point, connecting Caversham with Green Island. A second parallel 1,407-metre (4,616 ft) tunnel – the first double-track tunnel in the country – was built starting in 1907, and all rail traffic moved to the new tunnel in 1910. Caversham was served by its own railway station until its closure in 1962. There has been a long-running campaign to have the older tunnel converted into a cycleway, though this scheme has never gained wholehearted council support.By the 1870s the population of Caversham was growing rapidly, and in 1877, with the population at around 4,000, it was declared a borough. It held this status until amalgamation with Dunedin city in 1904. The borough's area included much of modern Forbury and St Clair, as well as what is usually regarded as Caversham today.
