Emily is kind and friendly and always sensitive to the other engines' feelings however, Emily can tend to get into trouble because of her fussy and bossy attitude, but she is nicer than she lets on. She seems to want to strive to be one of the best, and it sometimes causes mishaps, though she usually makes up for her mistakes when she realizes her errors.
Emily is a GNR Stirling 4-2-2. The last surviving engine of her class, No. 1, now resides at the NRM in York.
