eddie is a L&YR engine consept that was sent too the scrap yards cause it was really hard too operate and nobody wanted too use it when he escaped and hid on the LB&SCR where he met Louie a hybrid a Great Central Railway (GCR) Robinson Atlantic locomotive, which is a 4-4-2 tender engine and a LB&SCR K class really useful but too much money too manufacture so only Louie was made and helped Eddie hide cause he saw eddie as a version of himself that didnt get his happy ending and he hid Eddie in the back of his shed since he had his own and he kept eddie there and his driver and fire man helped and thats when mark found out and helped keep the secret but eventually eddie got caught when on his run at night so he doesnt rust and Mark Eddie and Louie were sent away and were moved too many different railways until ending us at a very cheap price and sold too a starting railway called the T.A.R. and they stayed there theyre new home and they sometimes took trains too other railways like the THSW railway and the trio stayed friends forever
