Hiro once lived on a faraway island. He was the strongest engine on his railway, and was famously known as the "Master of the Railway". He was eventually brought to Sodor where he worked for many years. However, he began to show his age, and the works did not have the necessary parts to repair him. To escape being scrapped, he was put on a siding, where he had to wait for the parts to come from his homeland. However, the parts never came and Hiro was all but forgotten.
