An ecclectic set of power works the hump in Union Pacific's Davidson Yard in Fort Worth, Texas, on October 16, 2011. The lead engine is UP SD40-2 8952, which is ex-UP B4229; ex-UP 4229; originally MP 3229. Following that, with a headlight that is just barely hanging on, is Locomotive Leasing Partners (LLPX) GP38-2 2277 (ex-UP 441, ex-UP 1941, ex-EMD 801, ex-CR 8001, originally PC 8001). Finally, the third engine is UPY RP20BD (UP calls it an RP20GE) 2649, which is a B23-7 rebuilt by RPI. This was built as Missouri Pacific 4631 (later numbered UP 131).
