Brace and Francis Mason. This work, written in the early 20th century, focuses on the engineering and construction challenges associated with the New York Tunnel Extension of the Pennsylvania Railroad. The likely topic of the book revolves around civil engineering techniques, specifically the methods and processes used in tunnel construction. The publication details the extensive process undertaken to construct the tunnels that extend from the Pennsylvania Railroad Terminal Station. It encompasses various aspects such as the contract signing, excavation methods, handling of spoil, and the installation of ventilation and power systems. The authors describe the innovative techniques used, including top heading and bench methods, the construction of shafts, and the elaborate planning required to navigate the complex urban environment. Through numerous illustrations and technical descriptions, the book highlights the challenges faced due to varying rock conditions, the need for precise engineering to avoid damage to surrounding structures, and the methods employed to ensure the project was completed effectively and efficiently over a span of several years.
