After being on display all weekend at Fullerton Railroad Day, Santa Fe 4-8-4 3751 backs down the spur toward the mainline after Amtrak's eastbound Southwest Chief has departed for Chicago on May 3rd, 2015. Engineer Matt Casford had mentioned to me that they would "put on a show," and he kept his promise, enhanced by the low afternoon light. The assembled railfans, many of whom can be seen in this photo, were certainly not complaining! (And the jacaranda trees are adding a little color, too.)
