We stop at Tucson at 6:03 a.m. MT, just as the sun begins to make its way above Mount Lemmon and the mountains of the Coronado National Forest. During the stop, we take on water in the dining car and fuel for Engine 2 (the primary) and Engine 840. There was talk they would fix the refrigeration system and restock the food in the lounge car here in Tucson, but according to our car attendant, Rick, there were no mechanics. And thus, still no food requiring refrigeration. We leave the station at 6:42 a.m. and are now 5:22 behind schedule.
