The Journey Beyond Sodor is a 2017 Thomas and Friends Film. It is the last ever Thomas and Friends Production to have a narrator
On his way to deliver a goods train to Bridlington on the Mainland, Henry suffers an accident due to a faulty signal and has to be taken to the Steamworks for repairs. Thomas is upset that Sir Topham Hatt chooses James to take the train in Henry' place. Thomas collects the goods train before James so he can take it to Bridlington himself ("Somebody Has to be the Favorite"). However, the Troublesome Trucks disorient him and he arrives at a canal where Beresford, a crane, refuses to let Thomas pass. Thomas tricks Beresford into letting him pass through ("Who's Thomas?"). Thomas arrives at a rundown shunting yard where he meets Lexi and Theo, failed experimental engines who are no longer in service. They provide him with more coal and water but are unable to help him find his way to Bridlington.
Thomas later finds himself at a massive Steelworks factory run by Hurricane and Frankie who invite him to stay ("The Hottest Place in Town"). Thomas initially declines but the Steelworks engines eventually persuade him as it is already very late. The next morning, Thomas learns that Hurricane delivered his train to Bridlington during the night and Frankie convinces him to help out at the Steelworks as to return the favor. However, they refuse to let Thomas leave and continue to force him to work for them. Thomas laments for his friends on Sodor and mounts an unsuccessful escape ("I Want to Go Home"). Thomas attempts another escape during the night and is this time successful.
He meets Merlin, a third experimental engine who falsely believes he has invisibility powers, who helps Thomas evade Hurricane and Frankie. Thomas is upset over his failures and the experimental engines remark that he is just like them ("We Can't Do Anything"). Meanwhile, on Sodor, James is begrudgingly running Thomas' branch line in his absence. Percy suggests that James go to the mainland himself to find Thomas. At Bridlington Goods Yard, James learns from the Troublesome Trucks that they were ultimately delivered by Hurricane. Hurricane, who is still there, spots James asking about Thomas.
On his way back to Sodor, Thomas sees that Hurricane and Frankie are taking James to the Steelworks. Thomas enlists the help of the experimental engines to rescue James from being captured. Theo and Lexi distract the Steelworks engines while Thomas and Merlin try to help James escape. The plan quickly goes downhill and Thomas is put in harm's way when he almost gets melted by molten slag. Hurricane pushes him out of the way, but his wheels melt as a result. Frankie is upset that Hurricane will not be able to help her make deliveries and explains that they are overworked at the Steelworks, which is the reason they tried to enslave Thomas and James. Thomas suggests that the experimental engines help them out. Although they are unsure if they are capable, they are still happy to try.
On their way back to Sodor, Thomas and James apologize to each other. Thomas explains to James that being friends is more important than being the favorite ("The Most Important Thing is Being Friends"). Henry returns and asks what he missed in his absence.
