On March 26, 1973, Santa Fe Alco RSD-15s 9846 and 9805 are on a Speno rail grinder train moving east at Chino, Arizona, about four miles west of Seligman on the Kingman District. The work train had been grinding surface imperfections from the rail heads for several days. The westward main track is just to the right out of the photo. Photo by Joe McMillan
