This is a bad configuration: the trams can get screwed at the T junctions and I advise you to bulldoze the unnecessary intersections for traffic fluidity.Here's my bash at a tram terminal - I decided to place the depot nearby just to get use to the idea: http://cloud-2.steampowered.com/ugc/540706343841951478/A70785821BCC66D4996C2F7DE684EF53E7CA8528/

On the contrary, I've had two of these 'terminals' running all day. The screenshot I posted has been fine all day, but admittedly, the second one did become overrun, so I redesigned it, and it's now running fine - the main issue was I couldn't completely bulldoze a road due to the bug I described above. But I've also found it is where you place your stops so not to overlap with other lines. Solve that problem and the terminal design works great.
I was said this to you because I have seen a screenshot where a such configuration caused a huge tram gridlock, the guy assigned to much trams to the depot and they were not fitting in.
