Emily is a beautiful Emerald colored Stirling single 4-2-2 Steam engine and the tritagonist from Thomas the Tank Engine & Friends (alongside Gordon).
When Emily was new to Sodor, she was ignored by the other engines for borrowing and pulling Annie and Clarabel without Thomas' permission or knowledge. The matter was resolved after she saved both Thomas and Oliver from nearly having a nasty accident on the cross-points and she was rewarded with two new coaches. Emily proved to be kind-hearted, as she was the only engine concerned about Henry when he was ill due to leaky tubes, she stuck up for Salty when Thomas and Percy were teasing him and suggested that Bulgy help the farmer deliver his vegetables around the island, after his passenger services went wrong with some naughty hens.
However, Emily has proven to be a nuisance on occasion as she bossed everyone about when they were clearing up after a storm, Thomas when he was taking passengers and Percy when he was shunting trucks. When pulling the express for the first time, Emily was determined to keep to Gordon's timing. Unfortunately, she became impatient and ran out of water.
Later on she was assigned to the Flour Mill, while James was assigned to the Misty Valley Branch Line, primarily the Black Loch. James told her that there was a monster in the Loch. She had trouble with the Flour Mill and ended up crashing some trucks off the line. She was later reassigned to the Misty Valley Branch Line replacing James. She discovered that the monster was just a family of seals and she is presumed to still work the line as it has never been stated otherwise.
When Thomas had to stay at Knapford Sheds, Emily did not like his company at first as she did not want any noise; she just wanted some sleep. However, she learned how comfortable it is to have the company of friends, missing Thomas when he did not return to the sheds. Originally disappointed once Tidmouth Sheds was rebuilt, she was delighted to find that the shed had gained a seventh berth and she was transferred there to be with her new shed mates.
Like most engines, Emily can get quite puffed up in the smokebox. When she was called "Excellent Emily," she ignored the advice of Murdoch, Thomas and Duck. This ended up getting herself into trouble and she later took their advice to get her job done.
Emily tries her best to make her friends happy. When she assumed that Mavis was sad, she took flowers to the quarry which only created a mess. When she tried to help her friends with the football/soccer match, she neglected to fetch the dirty washing which turned out to be the football team's uniforms. Also, when the Fat Controller lost his top hat, Emily went to find it without success and then took the special Christmas train without permission. However, she made amends for her friends' sake.
She later took Paxton to the Vicarstown Dieselworks after he was damaged during an accident at the Blue Mountain Quarry.
When Thomas hid his snowplough, Emily had to do Thomas' work and saved him when he got stuck in the snow again.
Thomas told Emily about the Flatbeds of Fear, but Emily did not believe in it and said there was a sensible explanation. She eventually believed in it, until Thomas told her that it was just one of Salty's tall tales. Later, she was very excited to collect a special which was a giant model of a globe of the world to take it to the Animal Park. However, it accidentally fell off and she spent some time chasing after it.
When the other engines tried to clear the tracks of snow for Connor to deliver the last train for Christmas, Emily was unable to clear them from the Sodor side. She was soon happy to see Hiro as he cleared it from the other direction and was later disappointed when they mistook Harold for Father Christmas by believing his red port lamp to be Rudolph's nose.
After Emily was informed by Paxton about the rumour that Toby was to be scrapped, Henrietta overheard this and knew it was not true. Emily took her to find Toby and once they found him safe, Emily gave him some of her coal.
When Henry confided in Emily that he feared catching chickenpox from Stephen and Bridget, she assured him that he could not get chickenpox and joked that he worries too much.
Emily became fascinated with Caitlin being able to go at such high speeds and wondered what it would be like to be fast, becoming depressed when she could not do so. However, in the end, she managed to save Caitlin who descended down a steep hill with broken brakes.
When Thomas was fed up with Diesel's selfishness during the holidays, Emily partook in Thomas' plan to mend the diesel's ways, much to her joy and amusement. She later attended the Earl's Christmas lunch with several other engines, including Thomas and a reformed Diesel.
Emily was one of the other Sodor engines that took part of the Great Railway Show and competed in the Best Decorated Engine Parade along with James, but the two lost to Rajiv. After Percy dropped out of the Shunting Challenge, she encouraged Thomas to take his place, declaring him Sodor's last chance to win.
Once, when the Fat Controller was ill, Dowager Hatt took charge of the railway. She assigned Emily to Thomas' job of pulling Annie and Clarabel while Gordon was assigned to her job of taking scrap to the scrapyards. This resulted in lots of confusion and delay, culminating with a massive hold up outside of Knapford. Emily pointed this out to the Dowager and was able to help her get things back on track before the Fat Controller returned.
Later, Emily helped Donald and Douglas pull a heavy train of steel pipes to Vicarstown, but the journey became difficult when the twins kept teasing each other and arguing about swapping places. When they stopped on Gordon's Hill, Emily was left holding the train while Donald and Douglas continued to bicker. Eventually, Emily slipped down the hill and was knocked off the rails by a giant, heavy snowball, which had formed from a lump of coal shaken out of Donald's tender when Douglas bumped him. Once Harvey had cleared up the mess, Emily took the front while both twins pushed and they reached Vicarstown without any further trouble.
Following a storm on the Island of Sodor, Emily took the Sodor Rangers on a camping trip to Callan Castle, so that Nia had more time to finish her shunting in the yards. After going over bumpy and flooded tracks, Emily ended up derailing whilst trying to get a fallen tree off of the line. Later that night, Nia brought her the truck of camping supplies she had forgotten to pick up from the yards - fortunately, the Rangers were able to set up a camp using the survival skills they had learned. Emily and Nia stayed with them throughout the night and the next morning she was put back onto the tracks.
One time at Tidmouth Town Square, an unveiling of a sand sculpture was to take place. Sir Topham Hatt sent the Steam Team off in pairs to help out. Emily didn't have anyone to work with and felt left out of not having a best friend. She got so distracted trying to find one that she nearly forgot about her job of delivering the final load of sand to finish off the sand sculpture. When Emily went back for it, her trucks were missing. She went to the unveiling and informed Thomas. Luckily, Thomas noticed Emily forgot her trucks, so he delivered them for her. Emily, feeling relieved, thanked Thomas and was happy to be surrounded by such good friends.
After fetching Rocky to save multiple engines from an accident, the Fat Controller rewarded her actions by making her the railway's official "safety engine" in addition to painting a number twelve on Emily.
Emily was introduced as being kind, compassionate, and always sensitive to others' feelings. If she wrongs someone, knowingly or not, she is quick to apologize. From the eighth to the sixteenth series, however, Emily experienced a personality change, developing a habit of being fussy and rude to others. She strove to be the best and sometimes caused mishaps, but always made up for them when she realized her errors. From the King of the Railway onwards, Emily has been portrayed more closely to her original personality, with subtler shades of overconfidence. She also often acts as a voice of reason, particularly when James gets too big for his wheels, or when a friend needs moral support.
- In Real-life, the only surviving member Stirling single of her class (No. 1) is on display at the National Railway Museum.
- She is the second female locomotive introduced in the series, the first being Lady.
