A view of the rails below from a bridge that crosses over from Seibuen Station to the residential area behind the trees.
Seibuen Station is the last station on the Seibuen Line. Actually, it is one of two stations on the Seibuen Line. I'm not sure if you can actually call that a "line" but it's been called that since 1952. That's a pretty long time for someone not to contradict this, so I'm guessing the length doesn't matter.
To tell you the truth, this station is not technically in Tokorozawa. The border is right next to the station so it's really in the neighboring Higashi Murayama-shi. But I wanted to use it so I've added this old sign below that says "Seibuen Station (left), Seibu Yuenchi Station (right)."
