From Denpa:
All aboard! This book is your ticket to seven romances―from confessions in Iriuda to proposals in Enoshima and all points in between. Beloved josei and boys love mangaka Asumiko Nakamura returns to the English market with a unique collection of romance shorts each set around Kanagawa's railway system, the Odakyu. Combining moments of contemporary women, lesbian romances and coming-of-age tales, Maiden Railways is a ride to romance rarely seen in manga these days.

Volume 1 is a collection of short stories. Volumes 2-4, titled "Kimi Youbi," are part of a spin-off series about two characters originally featured in one of the short stories.
