KATO N700 Series Shinkansen Starter Set Special, with Unitrack rails and power pack. Used a few times. The power pack works, but the motorized car doesn't move, possibly due to a malfunction. One 124mm rail from the set is missing. As a bonus, rails other than those in the set are included (see photo 5). There are two 62mm rails among them, so it is possible to build a course. No instruction manual or guidebook included.
