ya know she looks identical to Rosie
No. She's way more different. She has a diffferent but similar class to Rosie, and no, it's not a variation of the SR 100 tank engine class.
As soon as I see her on the show I can't wait to humanize her.
She's, surprisingly, a China Railways GJ Class 0-6-0T, NOT an S100 as most people have assumed.
Aww look at those cute Asian eyes
She looks like Rosie with Ashima's face.
