Not so Dudley --- the loop connected to the other track; would have had to be clockwise in operation.

As I recall it, and the photos of excursion trams on the loop already posted, indicate, trams from Carlisle Street turned right into Ackland Street, and then left into the loop. They stopped there, and on departing continued south to turn east onto the Carlisle Street main line. Anti-clockwise operation.
The discussion on the bus page queried the radius, from Google it would have been about 22 m - about 70 ft - at its sharpest. Well above the Melbourne minimum of about 15 m (I recall that the Oporto tram was not permitted to traverse all lines as its minimum radius was 18 m - or something like that.
