Rosie

**Rosie the American Engine** is one of the deuteragonists of the Seventyverse, and the thirty-seventh engine on the North Western Railway. However, she was either the twenty-first or twenty-second engine purchased for the North Western Railway.

## Backstory

Rosie, then built as No. 73, used to work in the USA before being deported to the Southern Railway in the UK. While there, she had a scary day when she rescued some children from an air-raid. A child put a rose on her buffer to thank her, and she dubbed herself Rosie ever since. Sometime later, Rosie was transferred to the Midland region where she worked with Arthur, Jinty and Pug.

## Ffarqhuar branch line

### Thomas

Due to Rosie's class replacing Thomas' class at Southampton Docks, the blue tank engine had doubts about Rosie from the start. This caused both engines to get into fights, which didn't help that Rosie was being put on a pedestal by Bridget Hatt at the time. However, when Rosie had to help Thomas with the post train, the two slowly started to connect. Rosie admitted to Thomas that she had lost most of her siblings too, and both were ultimately able to heal. Even now when Rosie at Vicarstown as a shunter, the two engines manage to stay in touch.

### Percy

Not much is known about Percy and Rosie's relationship, but the former was grateful for the latter's help when Arry and Bert were derailed. Rosie has also helped out on the Ffarquhar branch during the London trip. The two have stayed in touch since Rosie's transfer to Vicarstown. Rosie also knew Percy from when he used to visit down at Barrow-in-Furness.

### Toby

Not much is known about the relationship, but Toby appreciated Rosie's help during the London trip. The two still remain in touch after Rosie's transfer to Vicarstown.

### Daisy

Rosie and Daisy are often at odds. Daisy being a girly-girl who wanted to take only passengers, and Rosie often does goods work and is a tomboy. Once, Rosie insulted Daisy by calling her lazy, and that resulted in her taking trains that she couldn't handle.

### Mavis

By contrast, Mavis and Rosie's relationship is quite strong. Rosie assisted in the quarry to help Mavis when she was on the London trip, and they work very well together. Their relationship took a hit when Rosie was painted lavender, and she was pretending to be something she wasn't. However, when Mavis broke down and Rosie had to work at the quarry, Mavis was overjoyed to have Rosie back.

## Station pilots crew

### Charlie

Rosie and Charlie are quite the practical jokers, and do get along quite well. Rosie does get annoyed at Charlie's more reckless actions though.

### Diesel

When the London trip was going on, Rosie was patient and willing to listen to Diesel's worries about Jackie. She also found him to be a hard-working station pilot and had lots of respect for him. However, when Diesel went to keep an eye on Arry and Bert at the Ironworks, their relationship was very strained.

### Stafford

Not much is known about their relationship, but Rosie finds Stafford hardworking, but a very quiet sort... in more ways than one.

### Dennis

Rosie often makes jokes at Dennis' expense of his laziness, much to his displeasure. Rosie is also the more organised of the pair, and she often whips him into line.

## Odd jobs crew

### Harvey

Not much is known about their relationship, but Rosie does respect Harvey for helping out in the yards from time to time.

### Amanda

Not too much is known about their relationship, but it was actually Amanda who took the first step to bring back Rosie's true self by having her swap jobs with her. In the present day, their relationship is pretty good.

### Paxton

Not much is known about their relationship, but Rosie does find Paxton to be very kind, and she laughs at his remarks.

## Other relationships

### Arthur

Rosie and Arthur worked together on the London Midland region following Rosie's transfer. They also often met up with Percy when he told his stories of his escapades on Sodor. Arthur and Rosie also helped out when the Sudrians went on the London trip. Rosie found out the truth with Clarence much later on in life.

### Jinty and Pug

Like Arthur, Rosie worked on Jinty and Pug in the London Midland Region. The tank engines also met up with Percy when he came to Barrow to tell stories of his escapades on Sodor. Rosie, Jinty and Pug also worked to help out the engines on the London trip.

### Salty

Rosie had doubts about Salty, much like Thomas did, due to the fact that the Class 07s replaced her class at Southampton Docks. It's currently unknown how their relationship was patched up, but in the present, the duo are on good terms.

## Romance

### Stanley

It isn't exactly known how Stanley and Rosie got together, but their romance will be explored in future stories.

## Personality

Rosie is a very hardworking and cheeky tank engine who isn't afraid to get her buffers dirty. She had seen some disastrous horrors and unfortunately has a bout of trauma over that. Thankfully, she has seeked out professional help and has a very keen eye for if someone else is in need of that too.

## Technical Details

### Basis

Rosie is based on the Southern Railway (SR) USA Class. The class originated as the United States Army Transportation Corps (USATC) S100 Class, which were designed and built for shunting duties in Europe during the Second World War. After the war ended, fifteen of the S100s were sold to the Southern Railway, who modified them for use as dockyard shunters at Southampton. There, they worked alongside the London, Brighton and South Coast Railway (LB&SCR) E2s (Thomas' class). The SR USA Class was replaced by British Rail (BR) Class 07 diesels (Salty's class) in 1962, however some members of the class remained in service on departmental duties until 1967.

Four members of SR USA Class are preserved, including one at the Bluebell Railway. Over one-hundred of the USATC S100 Class - of which the SR USA Class are a derivative of - still remain, or are preserved, in various conditions in some European countries, the United States, China and Egypt. In addition, several Yugoslavian-built copies of the S100 design also exist, including two that have been shipped to England and modified to represent USA Class members. Rosie was specifically based on No. 73. This engine was built in America in 1943, sent to Britain not too long after, withdrawn on the 8th of January of 1967, and scrapped June of the same year.

Nathan is also based on a SR USA Class.

### Livery

When she first arrived on Sodor, Rosie was painted lavender with light grey tank panels, red lining and gold boiler bands. Her wheels were red with light grey rims.

After the events of Rosie and the Runaway Horse, Rosie is painted in the North Western Railway's livery of cherry red with dark raspberry tank panels, gold boiler bands and light grey lining. The area above her wheels and around her ladder are painted gold. Rosie has her company's initials (NWR) painted on her tank panels in light grey with a gold shadow, along with her number 37 also in light grey with gold shadow under her side cab windows. She still retains her original red buffer beams and wheels with light grey rims, however.

The font style of Rosie's NWR initials and number 37 is the same font that is used on fellow SR USA Class, Vulcan 4446, now No. 30072 of Keighley and Worth Valley Railway.

As Supertank, she wears a red face mask on her face, a symbol with the letter "S" on her tanks and a short red cape attached to her cab roof. Her superpowers are Super Strength, Super Speed, Super Durability, Flight, Heat Vision, X-ray Vision, Telescopic Vision, Microscopic Vision, Freeze Breath, Super Breath and Invulnerability. Her weakness is Railtonium. She wears red reporter glasses and has the words "SODOR TIMES" written on her side tanks.

## Differences from the episodes

* Rosie was numbered 37 from the word go rather than later. Her old numbers were USATC No. 1974/SR No. 73/BR No. 30073. The 73 is a nod to her TV series number, backwards.
	+ On top of this, this particular tank engine was the last of the USA tanks to actually wear their number on the Southern Railway. 30074 never wore the number 74.
* Rosie's lavender livery was done because Rosie liked Alice's hair ribbons. Unfortunately, Bridget Hatt took this as a sign that Rosie was a girly girl and was pressuring her into doing 'lady-like' jobs. Her red livery came about due to a shortage of lavender paint, but she kept the livery in honour of helping her driver's daughter come together with her horse, and Nicola bought a saddle blanket that matched Rosie's livery.
* Rosie is in a romance with Stanley.

## Trivia

* In *Sodor Super Hero Engines*, her superhero alter-ego is Supertank. She is a spoof of Supergirl.
	+ Supergirl's birth name is Kara Zor-El and adoptive name is Kara Danvers.
