Traveling light engines on June 25, 2004, Union Pacific’s LJP45 “dirt train” local trundles into East Carbon under a spectacular thunderhead building over Utah’s Book Cliffs. Three Rio Grande SD40T-2 Tunnel Motors (5371, 5390 and 5349) serve as power for today’s local, which will pick up empties at the landfill operation at East Carbon and take them back to Helper.
