Lady is a magical tank engine who works on Muffle Mountain.
Lady was chased and wrecked by Diesel 10 long ago and was brought to safety by her creator and driver Burnett Stone. She was brought back to life with the help of Burnett's granddaughter Lily Stone after being stored at Muffle Mountain for years and helped Thomas defeat Diesel 10. She and Rusty later appeared in a dream from Thomas. She told Thomas how to resolve the problems Sodor was facing.
Lady is painted Magenta with gold head lamps on the front footplate, gold buffers, smokebox and funnel top, dome and whistles, side rods, lining and her name on each side in gold. She is also painted black on her cab roof, lower funnel section and her footplate.
