For some reason the train has come to a stop at Yampai. Could be for a water stop, although they could have taken water at Pica where all the wells were. Notice that the conductor and rear brakeman are walking forward inspecting the train. From Yampai, it is basically down hill all the way to the Colorado River. If a train does OK climbing this hill it should have no problems climbing the grade from Needles up to Goffs or the grade from Bagdad up Ash Hill.
