"Emily" Stirling is a large green Stirling Single. She was designed by Patrick Stirling and built at Doncaster Works in 1870. She speaks with a Glaswegian accent.
Emily arrived on Sodor in 1975 7 years after the Modernization Plan. Emily was ignored by the other engines for pulling Annie and Clarabel without Thomas' permission or knowledge. The matter was resolved after she saved both Thomas and Oliver from a nasty accident on the cross-points, and she was rewarded with two new coaches, Martha and Jennifer.
Emily is a feisty and fun-loving engine. She acts as a sisterly princess-like figure to the others, but can sometimes get into trouble because of her fussy and bossy attitude. She's a lot nicer and wiser than she lets on.
Emily is based on a GNR Stirling Single, approx. 50 ft 7 in long, of which there is only one left in the world, "No. 1", located at the National Railway Museum in York. She also has the maximum speed of 70 mph.
Emily is painted in the emerald livery of the Great Northern Railway with gold lining and chocolate running-boards.
