The UP Rio Grande heritage unit trails on the UP-CSX produce train. The train is just a few miles out from it's destination at Railex in Rotterdam, NY.
UP 5786, 4134, 7720, & 8668 power a 152 car westbound mixed freight.
UP's dirtiest engine makes it's way onto the Mojave Sub before backing into the West Colton Yard. A year ago this engine was barely dirty,http://www.railpictures.net/viewphoto.php?id=109951
The "Rock Train" enters West Colton Yard from Cabazon.
Easily one of the main reasons why SP's and now UP's locomotives are so filthy... the one and only Tunnel 5!
