The Aldens board a private train to New Mexico to return the turtle to its original home, and they encounter enemies of Reddimus along the way!

The Boxcar Children must continue the mission for the society and deliver more things, all around the globe!

When a local baker and his wife learn that the children are orphans, they plan to send the children to live with their grandfather, but the children have been brought up to fear their grandfather, whom they have never met, because he did not like their parents' marriage. But their grandfather turns out to be a wealthy and kind man. He adopts children and moves the beloved boxcar to his backyard so they can use it as a playhouse.
