| SP SW1500 2551, Tucson, Arizona, November 21, 1985, photo by Chuck Zeiler. Built in November 1969 (c/n 35244) on EMD Order 4561, it became UP 1135 on April 15, 1997. It has an unusual mix of axle bearings, suggesting the use of trade-in components, or perhaps the SP rebuilt them, I don't know for sure. |
