This (and a lot of your other illustrations) have a very "Alan Wake" aesthetic. Also similar to whenever someone converts a Stephen King novel to visual media. The nearly-vacant train hurtling through a desolate landscape filled only with pine trees here and there is pretty... Ominous. I think it's something of a talent to do horror-themed stuff without having to resort to monsters, murder or jump-scares. Just setting the scene and using implications to create a growing sense of unease.
On another note, the layout of the train car is similar to a metro car, but it's passing through the middle of nowhere; interesting... I second other guy's question.
