This structure in Olyphant isn't really a train station. It's more like a little covered area where excursion trains stop a few times year.
That is not to belittle its function. The station helps form a town square on one side of Olyphant's downtown. Olyphant is one of the few coal towns around here that still has a functioning downtown business district-- apartments, stores, restaurants... and this little building helps tie it all together.
