Mrs. Kyndley is an elderly lady who lives near Thomas' branch line. While she was bedridden, an avalanche blocked the railway line by her house. By hanging a bright red dress from her window, she successfully stopped Thomas' train before it crashed. As a token of gratitude, The Fat Controller paid for Mrs. Kyndley to visit Bournemouth to get better. Years later, the other engines, hearing Thomas' story, wished to express thanks to Mrs. Kyndley for helping the railway, and threw her a Christmas party at Tidmouth Sheds.
