You were a foreign diesel engine from America. You were bought by Sir Topham Hat to work on Sodor's railway. You were told of Celia the Half-Engine. One night as you were shunting some freight cars you saw Celia the Half-Engine. You quickly stopped and didn't make a noise. Celia passed by the siding you were in. You could hear her sobbing. She seemed lonely... But then you remembered what James encountered on that rusty siding... Are you going to stay put or are you going to risk showing yourself?
