The very last one is pulling it's next to the last one! So, in case you don’t understand that; the D&RGW 5371 was the very last unpatched and unrenumbered D&RGW unit on the Union Pacific. It is seen here wreathed in oil smoke doing it’s regular job, pulling it's next to the last Dirt Train local out of Helper, Utah. 5371's very last Dirt Train job occurred 3 days after this shot and then the 5371 was retired never to turn a wheel in revenue service again. It is now in the RR museum at Ogden, Utah. Location is on the Union Pacific Green River Sub. near Mounds, Utah.
