“Blue Train” comes from the Nashville Bluegrass Band’s 1991 album Home of the Blues. It was among the songs that earned the band its reputation for, as the phrase went, putting the blues back in bluegrass — a repertoire that leaned hard on blues feeling and Black gospel phrasing.
The song is a heartbreak ballad built on a familiar bluegrass image: the train as the vehicle of separation and sorrow, a “blue train” carrying broken hearts away. The band made a music video for it that found regular play on country television, unusual exposure for a bluegrass act and a sign of the group’s reach in the early 1990s.
