The yellow standard(s)

In the diesel era, Union Pacific is best known for their double diesels and turbine locomotives however the locomotives that ultimately brought standardization to the Union Pacific can't be overlooked.

 

In the 1970s this standardization came in the form of EMD's SD40-2. On their own the Union Pacific owned hundreds of SD40-2s, their ranks further swollen by the mergers of the 1980s and 1990s. The dawn of the 21st century called for a new standard, again it came from EMD and their SD70M. When the dust settled and production ended the Union Pacific would roster over 1400!

 

A chilly afternoon in February 2017 found a pair of SD40Ns teamed with a pair of SD70Ms working the Grand Island 'hauler' in Gothenburg, Nebraska. Nose to nose we can compare lines of 'snoot' 1587 (originally UP 3364) and 4409, UP's workhorses.
