Grand Central Station is a train terminal in New York City, and a bustling hub of activity. It's a majestic building where amid the din, travelers can find moments of reflection, as so many journeys started or ended there.
Mary Chapin Carpenter wrote the song after hearing an interview with an iron worker who was one of the first on the scene after the September 11, 2001 attacks on the World Trade Center. The interview aired on a New York City radio station on the first anniversary of the attacks, and it brought Chapin Carpenter to tears. "Those first few days there at ground zero, he felt it was a very holy place," she told NPR. "When his shifts were over, he felt this lifeforce was somehow asking for his help, and when he would leave his shift he figured, whoever wants to go, I'll take him with me, and he'd find himself just going to Grand Central Station, standing on the platform, and figuring whoever wanted to go home could just catch the train home."
Chapin Carpenter immediately started writing the song, and had it finished three days later.
