It is. The single line splits in two for the station and rejoins before splitting again as a junction that goes left to Oban and right to Mallaig. If you're ever up this way, it's a beautiful train ride to both locations. All the stations on this line are kept really neatly and are well maintained, thankfully, as it's generally such a beautiful part of the world, and many visitors come just for the scenic journey.
I know I said I love cities but even I love spending a few days up here surrounded by nature ;-)
