Switch points and frogs needed for stub terminals, but not needed for a loop.  Although it is nice to have a siding at a loop.
 
Also, with a loop, if large enough, the center part can be leased for a gas station.  Pirl St. comes to mind, but won't swear to it.
 
And management doesn't care if the motorman has to "lug" handles, farebox and supplies to the other end.  They do care if cars back up because of scheduled headway and congestion at the terminal.
 
Didnt' Vera Cruz shop double end cars to convert to single end?  Likewise Birmingham?
