Created in 2005 the Express were once known as the Edmonton Trappers. Purchased in 2003 by RSR sports which consists of Nolan, and Reid Ryan, and partner Don Sanders. The Idea of the purchase was to relocate the team to Round Rock, and affiliate with the Houston Astros. The affiliation would last from 2005 until the end of 2010. The team would then change to a new affiliation in 2011 with the Texas Rangers. This came as the group was part of the Rangers new ownership. The Express name comes from Nolan Ryan's name during his playing days of "The Ryan Express".
