 Characters 

 Thomas (voiced by Aaron Barashi (A Thomas Promise - The Mystery of Lookout Mountain) and Shaun Jemmett (The Great Bubbly Build onwards) in the UK and Meesha Contreras (A Thomas Promise - The Mystery of Lookout Mountain), David Kohlsmith (Blue Engine Blues - All Wheels On Track) and Kai Harris (Something Broken, Someone Blue onwards) in the US), is a cheeky but hard-working blue 0-6-0T tank engine who is always there to help his friends. He's always willing to upkeep a “Thomas Promise” and works hard to make up for any mistakes he's made. He simply wants to be the best little #1 tank engine he can be.
 Edward (voiced by No Voice Actor in both dubs), is one of the oldest engines on the Island of Sodor. He is patient, wise, kind and very hardworking. With years of experience under his buffers, he is ready for anything. Edward enjoys stories set in the past, but dislikes being teased about his age.
 Henry (voiced by No Voice Actor in both dubs), is a long and fast green tender engine who chugs around wishing everyone a breezy “Good morning!” He can be a bit of a worrier, and he prefers calm days. Henry loves pulling long goods trains and likes good manners and respect towards others.
 Gordon (voiced by Will Harrison-Wallace in the UK and Neil Crone in the US) is a wise engine who supervises the other engines. He likes to see others happy and to help the younger engines with his superior strength, but not when they are disobeying his expectations. Gordon is shown to have an interest in bird watching. Gordon’s boastful personality has been toned down significantly compared to the original show. While he stills remains stern, grumpy, and easily annoyed, he no longer belittles the smaller engines. Additionally, unlike Diesel or James, Gordon's arrogant traits were almost dropped completely. However, his egotistical personality can be seen in episodes such as The Super-Long Shortcut and Carly's Screechy Squeak.
 James (voiced by Tom Dussek in the UK and Luke Marty in both dubs) is proud of his shiny red paint work, and tries to keep it as clean as possible, but is always happy to see his friends and gives them a cheerful greeting whenever he passes by. He can pull any kind of cargo, but he mostly prefers to pull coaches. He is often shown to be quite careless, as he is constantly dropping cargo he is supposed to carry. However, like Gordon and Diesel, he is overall portrayed as much friendlier than he was in the original series.
 Percy (voiced by Henri Charles (A Thomas Promise - The Great Bubbly Build) and Oliver Milchard (The Great Bubbly Build - Sodor Sings Together) in the UK and Charlie Zeltzer in the US) is Thomas' best friend, and quite a jokester. He has a lot of hidden courage in him, most of which he isn't aware of. Percy also likes to ring his lucky bell to bring good luck to himself, or his friends in a bad situation.
 Toby (voiced by Toby Hadoke in the UK and Eddie Glen in the US) is an engine with a strong sense of humor and will work in any job that suites him. However his advanced age means that he has a hard time keeping up with the more modern engines, which can make him feel inadequate. Toby first came to Sodor when his old line on the Mainland was closed down. Before this, he spent many days working at a stone quarry.
 Emily (voiced by Marie Ekins in the UK and Kayla Lorette in the US) loves to keep the Island of Sodor safe and on track. If an engine needs advice or a helping wheel, Emily is the engine for the job. Emily acts as Sir Topham Hatt's private engine, however, Emily is far more confident and level-headed than the railway controller, though she does listen to him despite his dramatic speeches.
 Whiff (voiced by Matt Coles in the UK and Joe Pingue in the US) is a bit of a tech whizz who loves inventing new things. He believes that any old or broken parts can be re-used and recycled into something new and useful.  Whiff also seems to know a lot about the history of Sodor, like how there used to be tunnels under Lookout Mountain.
 Hiro (voiced by Dai Tabuchi in the UK and KIntaro Akiyama in the US) a wise engine who is willing to help his friends when they are in trouble.
 Ashima (voiced by Sandeep Garcha in the UK and Diya Kittur in the US), a friendly and cheerful engine, and always enjoys seeing her friends, particularly the Sodor engines. She is also fond of dancing, gladly taking the offer to join her friends when asked. Ashima doesn't mind getting her paintwork dirty, as long as it means being a really useful engine.
 Yong Bao (voiced by Lobo Chan in the UK and Patrick Kwok-Choon in the US), a brave tender engine from China. His visit to Sodor made Thomas a little jealous, but in the end, the two became good friends.
 Nia (voiced by Sade Smith in the UK and Talia Evans in the US) an orange tank engine from Kenya in Africa. She now lives on Sodor with Thomas and his friends. Her best friends are Thomas, Percy, Diesel, Kana, Carly, Sandy & Bruno.
 Diesel (voiced by Henry Harrison in the UK and Shomoy James Mitchell (A Thomas Promise - Race for the Sodor Cup) and Will Bhaneja (Percy Disappears - Sodor Sings Together) in the US) a diesel engine who lives on Sodor with Thomas and his friends. His best friends are Thomas, Percy, Nia, Kana, Carly, Sandy & Bruno.
 Kenji (voiced by Dai Tabuchi in the UK and Kintaro Akiyama in the US), a high-speed engine. He's super-fast and has won nearly every race there is to win in the world. He is also a kind, hard-working engine who loves helping Thomas, Kana, and all their engines friends.
 Kana (voiced by Chloe Raphael in the UK and Ava Ro in the US) a little high-speed electric engine that lives on Sodor with her friends. Her best friends are Thomas, Percy, Nia, Diesel, Carly, Sandy & Bruno. Kana also has two passenger coaches painted in the same livery as her.
 Riff and Jiff (both voiced by Jessica Carroll in the UK and Riff voiced by Addison Holley in the and Jiff voiced by Evany Rosen in both dubs) cheerful engines who act very friendly towards other competitors alike. Even when anything goes wrong for them, Riff and Jiff still act very positive.
 Farona and Frederico (voiced by Jessica Carroll and Matt Coles in the UK and Humberly Gonzalez and Thomas Santoro in both dubs) both are arrogant and snobbish in addition to lacking humility, not above boasting to Kenji and demeaning Thomas and Kana, as well as winding up the latter. However, both of them are very unsporting, and even resorted to cheating to try and win. This ultimately turned Diesel, who at the start of the race was one of their biggest fans, against them.
 Carly (voiced by Eva Mohamed in the UK and Jenna Warren in the US) is a very helpful crane who is always there to lend a hook when her friends are in trouble. She also acts as a sort of older sister figure to Sandy, and while the pair are generally inseparable, the speeder's tendency to go overboard often forces Carly to keep her manic antics in check. While bigger and generally more level-headed than Sandy, Carly admits that of the duo, she is the pair's muscle, whereas Sandy is the only one with the actual know-how to properly fix anything. Despite being far more mature than the rest of the Biggest Adventure Club, Carly is not above juvenile behavior, acting very flustered upon seeing Kenji during The Sodor Cup and hiding with the others during a Halloween storm.
 Sandy (voiced by Holly Dixon in the UK and Glee Dango in the US) is a very energetic speeder, and while not the biggest engine on the island, she still enjoys the company of her much larger friends, many of whom recognize that she is a valuable asset to their community. Sandy always participates in a game if she can, and one of her favorite aspects of a race is seeing who the winner is. As such, she'll follow someone closely to see if they'll win or not. Sandy is also very good with small repairs, swapping out Gordon's broken coupling with a new one in seconds without difficulty. Additionally, she is very inventive and likes to build all sorts of gadgets, such as Percy's Biggest Adventure Machine and new wheels for Skiff. She also enjoys playing in mud and sand, particularly the latter. Sandy is always ready to help out wherever possible, but at times she can be a bit over-enthusiastic and will often go overboard and try to make a complex solution for a simple problem.
 Troublesome Trucks (both voiced by Jai Armstrong in the UK and Jamie Watson and Cory Doran in the US) are rude towards most engines, and love causing problems, although sometimes they fail. They also tend to bicker with each other at times.
 Annie and Clarabel (voiced by Wendy Patterson in the UK and Catherine Disher and Linda Kash respectively in both dubs) are very motherly and respectful towards the engines, however, they are rather prone to complaining.
 Tess (voiced by Celeste Waldron in the UK and Kaia Oz in the US) as her name implies, is a troublesome crane. who won't hesitate to ask for help if she needs it. She even seems to care about others and show some concern for their well-being, prompting her to give helpful advice to them.
 Bruno (voiced by Elliott Garcia in the UK and Chuck Smith in the US) is described as being smart, relaxed and joyful. He loves making puns and will often use comedy to get through difficult situations. As a brake car, Bruno travels facing backwards at the rear of the train and thus has a unique perspective on the world.  Bruno is also autistic; as a result, he is detail-oriented and likes routine. Bruno in particular likes schedules and timetables and memorizes where all the tracks on the Island lead. For this reason, he is often entrusted with guiding more rambunctious engines such as Diesel and Kana. He also has a special interest in people, his favorite type being mechanics.  Bruno will often emote using his stepladders, which he flaps when sad or excited, or his lantern. He is also sensitive to loud noises and, when stressed out by them, will produce large ear defenders made of steam from his smokejack. Additionally, Bruno has difficulty maintaining eye contact and will usually be looking at his surroundings rather than whoever he is talking to - this does not mean he is not listening, however.
 Harold (voiced by Jai Armstrong in the UK and Bruce Dow in the US) is always on-hand and ready to help and rescue others who are in trouble or danger. He even utters phrases typically used by pilots, such as "Over!" and "Roger that!". But sometimes, he cannot perform his rescues alone, so he will often resort to asking others for help if he needs it.  Harold's personality is mostly the same as his personality from the original series, however, he no longer teases the engines about how railways are outdated.
 Bulstrode (voiced by Will Harrison-Wallace in the UK and Jamie Watson in the US) a calm and kind barge who can often be seen working at Brendam Docks, collecting freight to take across the big, blue sea, and delivering freight for the engines to collect. This is in direct contrast with his personality from the original series, in which he was ruder than even the rudest engines, and constantly complaining.
 Terence (voiced by Will Bridgewood in the UK and Kai Harris (first voice) and Milo Toriel-McGibbon (second voice) in the US) is a hard-working, fun-loving tractor, who works best when he's not stressed and enjoying himself.
 Skiff (voiced by Jai Armstrong in the UK and Jamie Watson in the US) is a fun-loving, brave sailboat, willing to take on any new challenge, even if it means a bit of help from his friends. He also appears to suffer from travel-sickness when travelling on flat, dry land.
 Cranky (voiced by Will Harrison-Wallace in the UK and Cory Doran in the US) appears to stick to his personality from the original series, being grumpy, and teasing the other engines. However, he is still a hard worker, and knows what it means to be really useful.  Despite his grouchy nature, Cranky has also been shown to have a soft spot for seagulls, which he doesn't like to show when others are around.
 The Troublesome Tankers (voiced by Jessica Carroll and Guy Harris in the UK and Naomi Snieckus and Matt Baram in the US)
 Santa Claus (voiced by Tom Dussek in the UK and Michael Dobson in the US) is known for his red hat & white beard, and he also loves to ride on his sleigh.
 Winston (voiced by Guy Harris in the UK and Ivan Sherry in the US) is Sir Topham Hatt's red track inspection car and is as devotedly thoughtful and loyal.
 Darcy (voiced by Jessica Carroll in the UK and Dana Puddicombe in the US) is a very enthusiastic driller who loves her job and she will do anything that she's asked to do.
 Sir Topham Hatt (voiced by Tom Dussek in the UK and Bruce Dow in both dubs), the owner of the Sodor Railway who arranges all the special events on the island. He is the only human character in the series thus far to actually interact and converse with the engines.
