Spencer is suddenly distracted by Gordon (voiced by UK: Keith Wickham/US: Kerry Shale) while Thomas moves Hiro to a new hiding place. Spencer finds them and gives chase, but without the last part, Hiro falls apart and is forced to a stop. While Thomas and Hiro wait for Percy with the last part, they hear Spencer's whistle and run. The Fat Controller accuses Spencer of stealing the trucks and demands he return them to Percy. 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). Hiro makes friends with all of the engines, but gradually grows homesick. 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. With nobody else to ask for help, Thomas tells the rest of his friends about Hiro. The Fat Controller finds out about this and scolds Thomas by forcing him to do Percy's work. Percy misplaces his own mail trucks and breaks down while doing Thomas's job, so Thomas brings him to the Steamworks. 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. 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.

Later, he's taken to the Sodor Steamworks for repairs, where he finds old parts for Hiro. 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.

There, Thomas finds an old abandoned Japanese engine named Hiro (voiced by Togo Igawa). Thomas's brakes fail after climbing a tall hill, and he runs out of control through an overgrown, abandoned line. 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. In his hey day, he was known as the Master of the Railway.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. He is old, wise, very dignified and enormously kind. Now he occasionally returns to Sodor to visit his new friends. He was the first engine to arrive on Sodor, but was left in a forgotten corner of Sodor until Thomas found him and helped to fix him up. No information Hiro is the wise Japanese engine, who was famously known as the " Master of the Railway" and the recurring hero of Thomas the Tank Engine.
