Lucy is a elegant engine

Bio
Lady once came to the Island of Sodor a long time ago, when she was found by Diesel 10, an evil diesel engine who wanted to destroy her. Lady and Burnett Stone both ran away from Diesel 10, but during the chase, Burnett used up all her coal and made her go too fast, causing Diesel 10 to catch up, and then he crashed her. Lady was taken back to Muffle Mountain and stored inside Burnett's workshop, where he spent years desperately trying to restore her to working order, but he did not have the right coal to make her steam.

Years later, Lady was still out of service, and without her, the Magic Railroad began to lose its magical energy. That all changed when Lily, Burnett's granddaughter, and Thomas brought a truck of coal from Sodor to Muffle Mountain, which proved to be the coal necessary to make her steam. Lady's face was revealed when she came back to life and she and Thomas returned to Sodor, where they were once again chased by Diesel 10, excluding Splatter and Dodge. Lady, Burnett, and Thomas successfully managed to defeat Diesel 10 and she gave the Conductor Family the Gold Dust they needed.

In Calling All Engines!, when the steam and diesel engines were facing a fallout, Lady and Rusty both appeared in a dream of Thomas'. She told him how to resolve the conflict between the two kinds of engines, by working together regardless of their differences.

Personality
Lady is a very special engine who holds the secret to the Magic Railroad. When she moves along the rails, she spreads Gold Dust with her special powers. She has been known to help Thomas and his friends, when there is no one else to turn to.
