Eagle, like Edward, is an old, wise engine. He is assumed James' brother, with differences between them. He came to Sodor the same time as 98462 and 87546, but stayed on Sodor. His friends are Edward and Thomas and his enemies are 98462 and 87546. He works on the Kirk Eonan Branch Line with Alice and Eryn.
Eagle is based on the L&YR Class 25 with an added pony truck and an Fowler tender, very much like James.
Eagle is painted in the NWR's crimson livery and yellow and black lining. He has crimson wheels and a crimson dome, the number 28 on his cab sides and the letters NWR on his tender sides. He carries his number in gold figures on his bufferbeams.
