route 6 was allocated to the line between glen iris and city (swanston street) on 21 november 1929, the same day that numbers were allocated to the rest of the swanston st trams. trams traditionally terminated at the victoria st terminus, but following an accident in 1991, trams instead terminated at the queensberry st crossover. due to congestion during peak hours at the crossover, some trams continued north to melbourne university. finally on 17 january 1996, a permanent shunt was built at melbourne university. from then on, route 6 trams were altered run full-time to melbourne university. following the creation of route 58 in anticipation for the construction of the melbourne metro rail tunnel on 1 may 2017, route 8 was discontinued. from then on, route 6 was instead altered to terminate at moreland instead of melbourne university.
