Utah has for many years participated in Daylight Savings Time, where the clocks are advanced one hour in the spring leading to additional daylight in the evenings. Since the Rio Grande Zephyr arrived at Provo at 8:25 p.m. on Monday, Thursdays, and Saturdays I often tried to take advantage of the new found lighting. Here #17 is stopped on the eastward main track while a westbound freights waits for the RGZ to depart town on the westward track. This 15 second time exposure was captured on 35mm Kodachrome 64 slide film with a Canon FT camera on a Focal tripod.
