Emily is a large Stirling Single tender engine.
GNR Stirling Single G
When she first arrived on the Island, she accidentally took Thomas's coaches, and no one would speak to her. However, after she rescued Oliver, all the engines welcomed her warmly.
Emily is based on a GNR G Stirling Single.
Emily is painted in the emerald livery of the Great Northern Railway with gold lining and chocolate running-boards.
Emily acts as a sisterly figure to the others. Emily is kind and friendly and always sensitive to the other engines' feelings. If she wrongs someone, knowingly or not, she is quick to apologise.
