Yes - but was also have older trams than that in service - a pure publicity photo probably would have used one of those (the old ones are also the iconic Melbourne trams).
Call it “the trolly” or “the tram.” Having “a train” requires a the capability to run variable-length consists of separable railcars. BART out here in the SF Bay Area would be an example.
I may have caused some confusion - the Flinders Street Station behind is the centre of a fairly large train network. You can't see any trains in the picture because they are all inside the station and lower down. But Melbourne has a large tram network as well and Flinders Street as the centre of the train network has a large number of tram using the streets around it so people can interchange.
Ah, so what we’d call a “transit hub” where riders can switch between several available modes.
