Emily

Emily is a Stirling Single tender engine. She works mostly on the Main Line and once ran the Misty Valley Branch Line. She also has her own set of coaches. Emily acts as a sisterly figure to the other engines and though she can be bossy at times, she has a big heart.

Biography
Emily is a GNR Sterling Single designed by Patrick Sterling and built at the GNR Doncaster Works. When Emily was new to Sodor, she was ignored by the other engines for borrowing and pulling Annie and Clarabel without Thomas' permission or knowledge, but she apologized and they became good friends.

Emily has been through a lot of adventures in the Thomas & Friends TV Series with all of her engine and human friends. These are the adventures Emily has in The Great Trackmaster Adventures of Thomas & Friends.

Personality
Emily acts as a sisterly figure to the others. She is kind, compassionate and always sensitive to the other engines' feelings. If she accidentally upsets someone, knowingly or not, she is quick to apologise. Sometimes Emily dose have a habit of being fussy, bossy and rude to others. She had strived to be the best and sometimes caused mishaps, but always made up for them when she realizes her errors and without being fussy she dose show subtler shades of bossiness and overconfidence. She also often acts as a voice of reason, particularly when James or any other engine gets too big for his/her wheels, or when a friend needs moral support.

Basis
Emily is based on a Great Northern Railway G3 Stirling Single 4-2-2. Designed by Patrick Stirling in 1870 with 8ft 1in driving wheels and outside cylinders, they were specifically built for high speed expresses between London and York. These locomotives were capable of hauling 280 ton trains at 50 mph, though they could reach 85 mph on lighter services. A total of 53 were built at Doncaster between 1870 and 1895, in three series introduced in 1870, 1884 and 1894 respectively; the last was withdrawn in 1916. The only surviving member of her class (No. 1) is on display at the National Railway Museum. The locomotive in preservation carried a small capacity Sturrock tender, which was given in its first restoration in 1910. Recently, a derelict original Stirling Single tender used as a water and sludge carrier was found in Peterborough and, after restoration, was paired with the locomotive in 2014

Livery
Emily is painted emerald green with yellow lining and brass fittings. She has chocolate coloured running-boards and her buffers were originally bronze but are now silver.
