The L&N came into what was then known as Intermont in 1891. It formally became Appalachia in 1906. This Craftsman style train station was built around 1910. Notably, it has a slate roof.
The card was printed by The Tecraft Company in Tenafly NJ. That company registered The Tecraft Company as a trade name in 1946, when it was over 70 years old.
Judging by the quality of the photo and comparing it to other Tecraft cards on line, I would think this card dates to the early 20th century. It’s in fair to good condition with just two minor creases.
Note: back in 2012, I’d posted a picture of how the station looks now. As the comment below notes, it’s a wreck.

This building still stands in Appalachia. It is basically just a shell now with boarded windows and plenty of graffiti inside.
You’re absolutely correct. I’ve added a link to a picture I took of it back in 2012. Thank you!
