the main line track is the straght track on the left, you can see where the side track is going to be and the angle of it off the main line. in the mountins and pine forest.
There are several ways to approach this decision, but ultimately the choice is yours, not ours.
You could make the choice based on a structure you particularly like. Or an industry you like.
You could make the choice based on the industries your prototype and region typically serves.
You could base the choice on the intended operations. How many times a week will the spur be switched? How many cars at a time? What kind of cars do you want the industry to use? Will the usage frequency of the spur match the single spur setup? Or would the industry constantly have to juggle cars around for loading and unloading because of the single spur service?
Or you could put the choice up to a popular vote of the forum, and agree to live by the results of the vote.
my thoughts, your choices

i might build a Transfer Shed w/Dock to put on the side track in the pine forest insted of the logging camp. the pine forest track will disapear in the forest from the main line. then have a dirt or graval road leeding away from it and going into the background.
If the siding is near pine forests, think about industries that use wood by products. Researching this sort of thing (not just by products of wood, but for example the by products of meat, leather, and other industries) can be very interesting and the internet can be extremely helpful.
This is just scratching the surface but this website has a wealth of information about various wood related industires that are not just related to making lumber from trees.

A veneer mill is one example, and at least in the 1960s box cars modified to carry veneer were very interesting because the doors would be removed and sturdy timbers would protect the opening, actually going through holes in the roof.
