UP SD40-2R 3540 leads autorack east near Sidney, NE June 1, 2005.

Who says SD40's don't lead priority trains any more? Here, SD40-2R 3540 leads two SD70M's and A CSX wide cab GE on an eastbound auto rack near Brownson, Nebraska on June 1, 2005. Today, the once common sight of SD40's leading is becomming rare as the workhorse SD40-2 fleet ages and is retired.
