Thomas and Gordon Off the Rails is a book featuring two stories of The Railway Series combined. It was later re-illustrated using My First Thomas-style illustrations.
This book is adapted from the stories Off the Rails and Down the Mine from Gordon the Big Engine.
Stephen Lings' illustrations are based on Clive Spong's illustrations and the last page of the illustration is similar to C. Reginald Dalby.
