This book belongs to a series of volumes which marked a significant moment in the development of atmospheric railways, revealing how they might become a viable competitor to the steam locomotive. These volumes proposed significant improvements to the systems of the day including an economically viable method for obtaining a vacuum using a vacuum vessel and air pump. The authors also considered the use of water wheels and steam power as ways to achieve a vacuum, concluding through economic analysis that a smaller engine and air pump could be used, constantly kept at work to maintain power. These innovations when implemented would allow for a reduced capital outlay, better performance, and opened up the potential for atmospheric railways to reach their full potential in the transport revolution.
