Little Bear's Adventures of Thomas & Friends: Hero of the Rails

Little Bear's Adventures of Thomas & Friends: Hero of the Rails is another upcoming Little Bear/Thomas & Friends crossover to be made by Hiatt Grey.

Plot
One summer on the Island of Sodor, Spencer (voiced by UK: Matt Wilkinson/US: Glenn Wrage) arrives to help the Duke (voiced by UK: Matt Wilkinson/US: William Hope) and Duchess (voiced by UK: Teresa Gallagher/US: Jules de Jongh) with the construction of their new summer house. After being an absolute nuisance to all of the other engines by teasing and bossing them around, Thomas (voiced by UK: Ben Small/US: Martin Sherman) accepts Spencer's challenge to a contest of strength, taking heavy cargo around the island. Thomas's brakes fail after climbing a tall hill, and he runs out of control through an overgrown, abandoned line. There, Thomas finds an old abandoned Japanese engine named Hiro (voiced by Togo Igawa). Hiro doesn't want the Fat Controller (voiced by UK: Keith Wickham/US: Kerry Shale) to find out, fearing he will be scrapped, so Thomas promises to keep him his secret and work to make Hiro "Master of the Railway" once again. Later, he's taken to the Sodor Steamworks for repairs, where he finds old parts for Hiro. He takes them with permission from Victor (voiced by UK: Matt Wilkinson/US: David Bedella), the Steamworks engine, only to discover that Hiro's hiding place is dangerously close to the Duke and Duchess's new summer house.

The following day, Thomas tells Percy (voiced by UK: Keith Wickham/US: Martin Sherman) about Hiro, and asks him to do his own job while he helps Hiro. Percy misplaces his own mail trucks and breaks down while doing Thomas's job, so Thomas brings him to the Steamworks. The Fat Controller finds out about this and scolds Thomas by forcing him to do Percy's work. With nobody else to ask for help, Thomas tells the rest of his friends about Hiro. They all work together in bringing Hiro new parts, distracting Spencer, and keeping the operation a secret from the Fat Controller while Thomas and Percy try to find the missing mail trucks. Hiro makes friends with all of the engines, but gradually grows homesick. On the day that the last necessary part for Hiro is to be delivered, Spencer discovers Percy's mail trucks, only to be cornered by Thomas, James (voiced by UK: Keith Wickham/US: Kerry Shale) and Toby (voiced by UK: Ben Small/US: William Hope). The Fat Controller accuses Spencer of stealing the trucks and demands he return them to Percy.

While Thomas and Hiro wait for Percy with the last part, they hear Spencer's whistle and run. Spencer finds them and gives chase, but without the last part, Hiro falls apart and is forced to a stop. Spencer is suddenly distracted by Gordon (voiced by UK: Keith Wickham/US: Kerry Shale) while Thomas moves Hiro to a new hiding place. The Duke and Duchess are furious with Spencer for abandoning his own work, and Thomas asks to assist him, in order to keep his eye on Spencer and to gain the trust of the Fat Controller. Meanwhile, the other engines visit Hiro to keep his spirits up. When Thomas finally decides to tell the Fat Controller about Hiro, Spencer tries to stop him, but he is foiled by a rickety bridge which collapses beneath him.

When Thomas explains Hiro's situation to the Fat Controller, he reassures Thomas that he would never have scrapped the "Master of the Railway", and the following day, Thomas and Percy bring him to the Steamworks. There, Victor and his assistant, Kevin the Crane (voiced by UK: Matt Wilkinson/US: Kerry Shale), work together to restore Hiro. Once he's as good as new, Hiro with Rocky (voiced by UK: Matt Wilkinson/US: Glenn Wrage) rescues Spencer, and they work with Thomas on the summerhouse. Spencer apologizes to the two engines, saying they are "both fine engines and fine friends." Hiro misses his home island, so the Fat Controller arranges for Hiro to return home. A farewell party is held at the docks, and Thomas promises Hiro that Sodor will always be his home too.
