Threading the needle In July 1984 on Wyoming’s Sherman Hill, a westbound Union Pacific grain train waits at Dale Junction, Wyoming, on Track 3, as an eastbound reefer train sits over on Track 1. Crossing over from Track 1 to Track 2 is a hot westbound led by a DDA40X and two SD40-2s, with the head end brakemen from both stopped trains on the ground making an inspection of the train threading the needle.
