With a snowy Continental Divide in the background, Union Pacific’s manifest freight from Salt lake City to Denver departs Tolland, Colorado, on September 25, 2000. Leading the train is what we used to call a “cinder block;” a Southern Pacific locomotive that was so weathered and beat that it looked like, well… a cinder block. SP SD40R No. 7302 leads former Rio Grande Tunnel Motor No. 8616, SD40-2 No. 3372 and GE AC4400CW No. 7054
