A/N Sarah's the Molly replacement. I decided to make her the one who took Molly's old job when the latter replaced Emily on the Steam Team and took Emily's work. On Molly's death, she took what Molly had been doing for her jobs and Molly's crew started working with Sarah's replacement, as Sarah inherited Emily's crew when the latter died. Sarah's a nice diesel, but her replacement isn't nice.

Hey, friends. I'm Sarah and this is my story. I came to Sodor quite a while ago, to replace Molly at her old job, after she took another engine's job over. I was built, tested and then I came here. I'm friendly, practical, a sensitive soul, yet kind and cheerful. The first time I cried was when I saw an engine heavily damaged from an accident in pain. I was dreadfully upset, seeing that. My eyes were so watery and I was sobbing and sniffling, because that engine's wails of pain just broke my heart. "Why do my eyes water when I'm unhappy?" I asked.

Driver comforted me in my hurting. "There, there, Sarah", he said, drying my tears with a cloth. "Let it all out. It's tears. You're crying because you feel strong emotion.". He listened attentively to pick up on my values and cues of the moment as he rubbed my cheeks and wiped my tear-wet eyes.

I cried some more. "Driver, I can't bear to see my fellow engine in so much pain," I sobbed, huge tears streaming from my eyes as he comforted me.

He said, as he continued to wipe my tears away, "No judgment from me. Just my care and compassion. I'm here for you, so just go ahead and feel what you're feeling. Crying's comfort, so I want you to cry it out. I shall stay here and dry your eyes". He pressed the cloth to my weeping eyes and wiped all my tears away as best he could.

I finished my cry after a while, emotions spent. Driver dried my last tears away, wiping my cheeks and eyes until they were dry. I smiled, feeling better, as he refilled my radiator.

I think I like Sodor. I know as long as I'm a Really Useful Engine, like my friend here Thomas says, I'm safe from scrapping. I've been here a while, but I've got a new set of jobs I'm learning now. I've heard the engine they got to replace me at my old work isn't a very nice diesel, unlike me.

A/N Sarah's a gentle giant, sort of a diesel Molly, because she's kind and a powerful engine.
