I'm aware that there is some space on the tram left vacant without seats, but I didn't know it was that much. The width of double seats is small and the personal space is unacceptable if shared by two strangers.
I'm aware that this class of low floor tram is mounted on bogies as opposed to fixed wheels on C & D class, which is supposed to increase its ability to negotiate track components and curves, but to my disappointment, the tram had to go through crossovers and curves with extreme caution, including the curve in Macarthur Rd. described as "moderate curve" in the drivers' training manual. Such locations is only a matter of cutting off power and allowing the tram to free wheel on WZAB class. The left white arrow at Thornbury is short and turned to amber when the first bogie was still crossing the first frog. The tram still had to traverse the curve at low speed, holding up north-bound traffic in St Georges Rd. On a Comeng tram it is possible just to floor the accelerator and shoot through. I'm aware of its high acceleration and total traction power, but there is hardly any straight long clear section without points, crossings and curves for it to stretch its legs. Service speed is nowhere near before.
The sliding doors are as slow as those on C & D class, making it impossible to obey the rule to keep doors open until the previous signal phase turns amber when having a red light at a safety zone (and platform stop). You just have to wait with the doors shut so that you are ready to go at any time, assuming there are no late runners intending to board.
I was also hoping that it could have mechanical gongs as those on Variotram, another low floor tram class by the same manufacturer at Dandenong, but it's electronic, which is also disappointing. It's not just a gong, it's part of Melbourne's character which we might lose completely after 2032.
The three classes of low floor trams have successfully avoided everything a Melbourne tram needs.
