tagging is the description of the geometry, together they form a representation of the world. Renderers pick those tags from the model in which they are interested in, and display them as they like.
No renderer has to render highway =track or railway=abandoned or anything else.
It is entirely up to the people making the rendering rules to decide which tag gets rendered, and how, and when (precedence, stacking order), and whether the geometry will be modified prior to rendering or will be taken as it is.
