Lady was chased and wrecked by Diesel 10 long ago and was brought to safety by Burnett Stone. She was brought back to life with the help of Burnett's granddaughter Lily after being stored at Muffle Mountain for years, and helped Thomas defeat Diesel 10.
Lady does not seem to be based on any real locomotive prototype, but it has been suggested that she bears some resemblance to a K&SER Northiam with the rear cab cut off and an enlarged chimney. She is said to be based on "Lively Polly", owned by the Liverpool Overhead Railway Company. She may also be partially based on a LSWR 0-4-0 locomotive. She does have some resemblance to a GWR 101 Class.
Lady is painted red-purple with gold head lamps on the front footplate, tail lamp, gold buffers, smokebox and funnel top, dome and whistles, side rods, lining and her name on each side in gold. She is also painted a very dark purple on her cab roof, lower funnel section and her footplate.

- Lady has a coupling on her back, but not on her front.
- Lady's face is only visible on Sodor.
- Originally Lady was not going to have a speaking role in Thomas and the Magic Railroad, her only way of communicating was "telepathy" with Thomas when he was on Muffle Mountain and her whistle. She was later given lines to help smooth over cuts made to the film.
- One of Lady's models is currently on display in Japan. Her full scale model is also being kept in storage.
- Lady's whistle sound was reused for Millie.
- Lady was the first female steam engine introduced in the television series, as well as the first non-Awdry standard gauge steam engine to be introduced into the television series.
- One of her concept art images depicts her as a 2-2-2, with several design changes.
