The G type Adelaide tram was a class of four single truck Birney trams manufactured by the US firm J.G.

They arrived in completely knocked down form and were assembled by the Municipal Tramways Trust in 1924.

[1] They were used exclusively on the isolated Port Adelaide network, mainly on the lightly trafficked Rosewater line to either Semaphiore or Largs.

[2][3] After that closed in 1935, all were sold to the State Electricity Commission of Victoria and placed in service in Geelong.

One was scrapped in 1956 after an accident, while the other three remained in service until the system closed in April 1972.
