The C type Adelaide tram was a class of 20 drop end, California combination trams built by Duncan & Fraser, Adelaide in 1918 for the Municipal Tramways Trust (MTT).

All were delivered in 1918, but as they were receiving second-hand motors from the E type trams, the last did not enter service until September 1919.

When the MTT introduced an alpha classification system in 1923, they were designated the C type.

[1][2][3] Because they were much faster than existing trams, they were nicknamed Desert Golds after a contemporary racehorse.

At least 10 were transferred to the isolated Port Adelaide network in 1930, the last returning after the Albert Park line closed in November 1934.
