A Southern Pacific CSUX coal empty climbs through the “S curves” at Crater, Colorado, on the afternoon of July 30, 1996. The head end with lone SP AC4400CW No. 298 has already passed through the cut that is visible at the top of the photo. Mid-train DPUs Nos. 217 and 371 climb between the curves in the middle, while rear DPUs follow below with Nos. 361 and 226.
