Stepney, later retitled Stepney the Bluebell Engine, is the twentieth book in the My Thomas Story Library series.



Stepney is sent to work at the quarry. That night, he is asked to take a night special to a building yard. Whilst returning home, Stepney gets lost. His driver and fireman look for help but while they are gone, two diesels arrive with the intentions of scrapping Stepney. Can someone else save him in time?
