Considering the Type 9s are CAF and seem problem free , I can see why the T went with them.

It's not the end of the world. Realize that the CAF Urbos 3 is used all around the world and that Sydney's problems are probably just related to that batch. Once they fix them, they'll redeploy them in other cities in New South Wales. Newcastle, for example, also uses those trams, and they're starting up a new tram network out of Paramatta that will also use CAF Urbos 3s, so they can use those there as well. The reason for replacing the Urbos 3 in Sydney is because the other two tram lines use Alstom Citadis cars which use the APS (Alstom Power System) which is essentially an on-demand third rail, and they'd prefer the Dulwich Hill line, which is the only line using the Urbos 3 because it is under wire the entire length, to switch to the Citadis for interoperability for demand leveling purposes.

They are currently being replaced by Alstom Citadis trams used on other lines.

I hope this isn't a premonition of what's to come.
