Union Pacific's HHEHE-08, called to duty before sunrise on the morning of January 8, 2010, awaits a westward departure spotted in front of the former D&RGW depot at Helper, Utah. On account of cold weather problems, the MRONY's departure east from Roper yard in Salt Lake City was severely delayed. It is uncommon for UP to assign a new ES44AC to swing helper service on the Provo Subdivision.
