Poppy the PATH train car loved carrying passengers back and forth from New Jersey to New York. When the World Trade Center towers collapsed on top of her on September 11, 2001, Poppy was buried under the rubble- but safe. Still, by the time Poppy opened her doors to people again, her purpose had changed. Now instead of moving people, Poppy gives them a place to pause and appreciate how, even in really hard times, they can find goodness.Marie Betts Bartlett, author and illustrator of "The Little Yellow Trolley Car," has captured the true story of a commuter train in a child-friendly book that is colored with warmth, resilience and courage.
