As viewed from the shoulder of US Hwy. 6, UP's Salt Lake-Denver (MRONY) manifest prepares to stop on track #2, just east of the crossovers at Castilla. In the distance, Union Pacific's First Help will flag by the red signal from main #1 to main #2 and couple to last car of the MRONY. Soon after, the long manifest will be on the move east toward Soldier Summit.
