A comprehensive study and the only one of its kind in English. Although the student of Austrian railway history will find very many similarities between this book and Slezak's Lokomotiven der Republik Österreich, both in content and presentation, recent researches on my part have uncovered various notes in other books from Mr.Whitehead's collection that suggest that he was doing serious research on his subject. Further, a personal recollection has come to me of Mr.Whitehead's friendship with J.O. Slezak, the Viennese railway publisher, so imitating a familiar format should probably be taken as flattery. ( )
