- “This little steam engine certainly packs a punch, he's incredibly strong for such a small light engine!”

Raul participated in the Great Railway Show's Shunting Challenge at least twice and won the championship at least once.
Once when he was being carried from Brazil to compete in England via a rail ferry, he accidentally arrived on the Island of Sodor when it made a wrong stop. Raul promptly backed onto the ferry, but not before Thomas corned him and attempted to start a conversation with him until being bumped out of the way by Vinnie.
After the Great Railway Show ended, Raul left the Mainland and returned to Brazil.
Raul is a feisty little tank engine from sunny Brazil who is an eager competitor.
Raul is based on a series of three vertical-boilered steam locomotives built by Sentinel in 1931 for the São Paulo Railway. The real engine carrying his number was in service at the Amsted Maxion railway equipment factory in Cruzeiro, Brazil from 1959 until October 2014. In 2015, it and classmate 167 were preserved by the ABPF; the third engine, 168, had been scrapped decades before. Their withdrawal marked the end of the commercial use of steam locomotives in Brazil. 166 is currently dismantled and undergoing restoration.
His basis is built to run on broad gauge rails, whereas Raul is standard gauge.
Raul is painted yellow, blue and green with blue lining. He has yellow and black hazard stripes painted across his running board and bufferbeams, and the number "166" on the sides of his cab in white, surrounded by a blue diamond.
He may appear in the twenty-second season.

- Raul's promotional video incorrectly states that he is based off of the Two-Engined Sentinel 7109. This engine was originally the inspiration for Logan's number.
- Raul had been partially modified to work on British rail: he has been given buffers and chain couplings. He has also been given a lamp.
- Even though his wheels are grey, his merchandise depicts him with green wheels.
- His whistle in The Great Race is actually Rheneas' at one half-step lower in pitch, while in the app Magical Tracks, his whistle is Spencer's a lower pitch.
