The Jim Henson Company has joined forces with Amtrak for a second year for a summer promotion featuring the preschool series, “Dinosaur Train.”

The Big Big Dinosaur Sweepstakes, which launched this month, gives families the opportunity to win an Amtrak vacation to Chicago and Washington, D.C.

As part of the national promotion, Amtrak will distribute 65,000 free “Dinosaur Train”-themed activity booklets and 1 million co-branded ticket jackets, as well as “Dinosaur Train” placemats, counter cards and seatback covers.

"Last summer's promotion with Amtrak was both fun and rewarding for all of our ‘Dinosaur Train’ fans and their families," says Melissa Segal, senior vice president of global consumer products, The Jim Henson Company. "Parents know that with Amtrak, traveling to the family summer vacation destination is all part of the experience.”

Details on the sweepstakes are available on the Amtrak, The Jim Henson Company and Tomy (“Dinosaur Train” master licensee) websites.
