This is a classic perspective of the tracks between (daylighted) Tunnel 28 and Tunnel 29. The red-ish rock just behind the last passenger car marks what is left of Tunnel 28. The reason for this passenger train was not known to any railfans. At least, no railfans I know. It was supposedly a deadhead move, although there was some speculation that perhaps it was related to the UP/NS merger announced on July 29th.
