After some maintenance in Union Pacific’s North Platte Diesel Shop, a worker carefully replaces a rooftop access panel on GE C44-9W No. 9829.

Union Pacific locomotives due for work and servicing gather inside the main building at the North Platte Diesel Shop on May 5, 2011. UP No. 9829 is a former Chicago and North Western GE C44-9W.

UP #9829 leads a mixed freight around the curve into Effingham.

Locomotives are being rearranged on Track 4 at Union Pacific’s North Platte Diesel Shop the morning of May 5, 2011.

I didn't realize that Union Pacific had decided to paint their locomotives BROWN . . .
