In contrast to conventional public announcements, this public art project commission was awarded to Jim Green for his creation of a series of musical chimes greeting travelers throughout the underground system in "Train Call." Constructed from traditional folk songs such as "She'll Be Coming 'Round the Mountain" these chimes function as melodic preludes to voice messages. Voices of local celebrities Adele Arakawa, Alan Roach and Mayor Michael B. Hancock deliver announcements in the train cars and on station platforms. The artist's intent is to humanize the traveler's experience.
