About Img


Design Nine, Inc. was formed in 1986 by Engineers from the former Missouri Pacific Railroad Company as a result of the merger with the Union Pacific Railroad Company.

These engineers each brought 10 to 15 years of working experience from various sectors of the Missouri Pacific Railroad’s engineering department to Design Nine. Their combination of their individual talents resulted in a company with a wide range of available railroad engineering capabilities.

Their philosophy on engineering was to provide superior services to clients through years of experience and honed ability. We are proud to say that, throughout our history, Design Nine, Inc. is still strongly rooted in the area in which we are the most qualified – railroad engineering.
