harry potter - Do muggle trains roll along the Hogwarts Express railway near Hogwarts without seeing the enchanted area?

This answer is all supposition, using no direct canon or WoG input that I'm aware of:

Most likely there are no muggle trains use that particular rail line, as the platform for the line is hidden. But even if a muggle train does uses it and goes all the way to the end, it would end up in Hogsmeade.

But, you say, Hogsmeade is a magical town. Sure it is. But it would be easy to set up some kind of monitoring ward on the tracks to warn the village of an incoming muggle brigade. The villagers could then prepare for the impromptu visit and look ordinary, if maybe not quite normal.

My memory wants to tell me that it wasn't uncommon for Hogsmeade to have muggle visitors anyway, to trade for odds and ends and the occasional tourist. But that might be made up.
