Question about the Keddie “Wye”

Every picture that I’ve seen of the Keddie Wye is the rather dramatic merger on a trestle of the line coming from Klamath with the one coming from Winnemucca going to Sacramento. My understanding of a Wye, however, means that there must be another unseen segment that allows a train, for example, from Winnemucca to proceed to Klamath. Is this true? If so, is it used very often?

Thanks for the answer, Mark.

BTW, the way I checked the spelling of “Winnemucca” was by referring to the map in “The Empire of BNSF” in the June 2001 issue. The lead picture, which I consider one of the most outstanding to appear in Trains in the past 5 years, is credited to you. Several weeks ago, I submitted that question about the telephone poles along the Transcon. That picture shows them behind the trains at left. So it appears that they must have been removed recently (within the past couple of years).
