King William Road section could be used for a siding to store trams for peak hour services and I feel it might be only used on event days such as AFL games and Cricket matches.k

You may well be right. However, they have installed a scissors crossover at the terminus. That implies a somewhat heavy use of the stop, even though the crossover is of an outdated design. Having said that, I really don't know what they have in mind, but why install a scissors crossover for infrequent use?

I should add that what is stranger is that scissors crossovers with old tech facing points are not something you'd install if there was any intention of extending the track any time in the near future. Those points are ok for termini where the speeds are low, but these days high speed points are used if they are not at termini. Again, I don't know what the background is, but it certainly looks like the Riverbank and North Terrace termini are there for some long time.

What are the physical differences between the scissors crossover which has been installed and one which would allow for higher operating speeds?

There was an article a little while ago (will try to find it in the archives) that mentioned modelling had shown that a significant impact to vehicular traffic would be caused by the introduction of an additional lights cycle for right-turning trams. Can't quite remember the specifics but I think the guy from DPTI touched on it in his ABC 891 interview yesterday where he said that without the additional lights cycle the trams could be run at 4-5 minute intervals but with it only 15-20 minute intervals. That's both lines, east-west and north-south.

I'd much rather take the hit on the right turn but have trams running at 4-5 minute intervals than allow the fairly few commuters who want to ride all the way from Glenelg to the east end to do that in one trip. I think he should have hit this point harder in the interview (and the knock-on effects to traffic by the introduction of the right turn) but it was difficult with that fella repeatedly and loudly asking him why an "artist's impression doesn't constitute a promise". ffs.

Presumably frequency of tram movements through the junction will be absolutely key when the additional City, Prospect and Norwood lines are built and therefore if a right turn was put in now it would be a temporary solution that wouldn't logistically be able to be used a few years from now. Imagine when the media got hold of that one - the $20M right turn to nowhere.

Providing it is true, I think DPTI should just release the traffic modelling showing with the right turn and without the right turn - I can't see how the usual pro-car sources could argue against that one.

No the loop will be a separate tram route......the light blue route in the map below, even though I think the southern edge of the loop will now be 2 streets south.

There are pdf files online showing the future plans including the City Loop route. Perhaps within the next 10 years we will have trams going to more suburbs, a tram every few minutes within the City and quick easy seamless transfers.

I think this file may be what you are looking for. This appears to be part of the formal Business Case being prepared for the future expansion of the network and it does make for interesting reading.
