[6] From 1 August 1977, Z-class trams were attached to Camberwell depot and commenced operating route 74 in readiness for an East Burwood extension.

On 12 July 1978, the terminus of the Burwood line and route 74 were slightly shifted east to Somers Street.

The two B1s were reallocated on 20 November 1987 to route 96 after the St Kilda Beach "light rail" extension opened.

Due to a Camberwell depot Z3 shortage, A-class trams were allocated there and started operating the route from 28 March 1994.

All Z-class trams assigned to Camberwell depot besides two Z3s—because of an A2-class shortage—were reallocated by January 1996 for the eventual network privatisation.

[18] During the 1999 election campaign, the Labor State Opposition committed to extend route 75 to Knox City Shopping Centre.
