Train call has been updated twice in the airport's history. The original edition of Train Call, which ran from the airport's opening in 1995 until 2007 and also recorded by Jim Green, featured the voices of local radio broadcaster Pete Smythe and former KCNC-TV anchor Reynelda Muse, who is notable for being the first woman and first African American to anchor a television news program in Colorado. A different set of sound effects accompanied the original voices which mostly came from bells and woodwind instruments and were based on western folk songs, such as "She'll Be Coming 'Round the Mountain" and "Home on the Range."
