Theme park operator Six Flags will open a Thomas Town family attraction at its park in Mitchellville, Maryland, US later this year.

Occupying 3.5 acres (14,163sq m), the new are will be the largest Thomas-branded attraction in North America.

Thomas Town will be the park's largest expansion in over a decade and will feature eight rides and attractions and a new retail store.

Guests will be able to take a ride on a replica train across Thomas' home island of Sodor and rides within the attraction include a Cranky the Crane Tower-themed drop tower, a Harold the Helicopter ride, a large observation wheel and a large themed play area.

The Knapford Station Shop, the park's first retail location since 2005, will feature themed merchandise, including the popular Thomas & Friends die cast trains, apparel, and storybooks.

John Winkler, Six Flags America park president, said: "Thomas & Friends have entertained and educated more than three generations with messages of teamwork and friendship.

"Now families who visit the park will have a new, permanent, place - the largest in North America - to enjoy and interact with these wonderful characters. We are delighted to welcome Thomas Town to Six Flags America and offer our guests more ways to experience family-friendly fun together."
