In Thomas & Friends, the Island of Sodor is home to the narrow-gauge Skarloey Railway which runs up into the hills. These lines and the engines that work on them are some of the oldest on the island. The narrow-gauge railway has some contact with The Fat Controller's standard-gauge engines (mostly at Crovan's Gate), however the location of the railway often leaves the narrow-gauge engines in relative isolation.
Victor is a dark red Hispanic tank engine in charge of the Sodor Steamworks. He supervises all the engines who journey in and out of the workshops, as well as Kevin, the clumsy yard crane. Victor always has a helpful, constructive disposition and is good-humored with everyone he meets. He speaks with a Cuban accent and spoke Spanish when he first came to Sodor.
Victor was introduced in the feature-length special Hero of the Rails. The show's staff were researching real-life engine workshops as inspiration for the Steamworks when they learned that one had a self-contained narrow-gauge line, used to transport parts internally. The staff decided they wanted an engine with a cab, and chose as a prototype ALCo's #1173, which was specially built for a sugar plantation line in Cuba. Some artistic licence was taken, as the original #1173 is a standard-gauge locomotive.
In Blue Mountain Mystery, it is revealed that Victor originally came to Sodor with Luke. Back then, he was painted bright yellow. Because Victor did not speak the same language as Luke or the crew on the ship, they could not understand him. While at sea, the chains holding Victor down to the deck of the ship snapped, causing him to roll freely along the short stretch of track that he was on. When the ship arrived at the docks, Luke asked to be taken up first. Victor tried to tell the crew about his chains, but they still could not understand him, so did not pay attention. When Luke was lifted off the ship, he accidentally bumped Victor, which sent him rolling backwards along the deck and into the sea. Luckily, Victor was saved by a jetty. It was a long time before he was lifted out, but instead of being sent to the Smelter's Yard, as Luke had thought, he was repaired. To communicate with the workmen, Victor learned their language, his first word being "red" because it was the color he wanted to be for his new life on Sodor.
