Recueil d'appareils a vapeur employés aux travaux de navigation et de chemins de fer

A publication by France's leading civil engineering contractor who played a major role in the construction of the French railway system. Some of the projects were technological breakthroughs, e.g., the introduction of steam dredgers which could excavate 1500 cubic metres of spoil per day and the construction of the Rhine railway bridge at Kehl, a milestone in foundation engineering. Castor was one of the major players on the European continent to realize the transition from manpower to machine power in construction projects.
