"Then strode he forth . . . like unto the flame of Hephaestus that none may quench." Homer, Iliad, Book 17, Lines 87-90.
According to Freeman H. Hubbard and the Glossary in his 1945 book Railroad Avenue, large, powerful locomotives were known to railroaders as "Gods of Iron" and so I introduce this topic with reference to the Greek God of Fire (his Roman name was Vulcan). When I think of our "Gods of Iron", the two foremost in my mind are the Alco Jabelmann Challenger and the Lima Allegheny and their Lionmaster and Rail King iconography. Assuming the perspective of a railroader living in 1945, which locomotives would make the grade up Mount Olympus? Which steamers on your layout have weariless fire?
