Looks like the anime is collaborating with not just Enoshima Railway, but also other railway services in the area.

You may "have a ride on it" through various YouTube videos, like this one: https://www.youtube.com/watch?v=ILPxleZIfXY (NOTE: It's a suspended monorail, which means you may not feel comfortable if you have acrophobia)

P.S. Removed pantyhose as her skirt is too long to be determined whether it's thighhighs or pantyhose underneath (and we don't have other backdrop-able legging-related tags for ambiguous situations like this).

Or we can use common sense and make educated guess

What commons sense? There're thighhighs/stockings with that color and fabric. That's common sense. Or do you mean you directly helped dressing up that girl in that image so that you actually know what she's wearing?

Because this character always wears pantyhose?

Is there any reference image of hers in casual wear like this? She might wear something else in a different costume like this other than her "common" ones like seifuku or bunny girl.

But your point is a valid one though.
