LXVIII, Sept.…" is a scientific publication authored by Charles M. Jacobs, a notable figure in civil engineering. Written during the early 20th century, this volume is focused on the technical aspects and developments related to the New York Tunnel Extension of the Pennsylvania Railroad. It serves as a detailed account of the planning, engineering challenges, and construction methods used to connect the Pennsylvania Railroad and the Long Island Railroad into New York City. The content of this publication encompasses Jacobs's professional observations on the evolution of the rail system's expansion into New York, detailing the history of the project, including feasibility studies, engineering strategies, and the logistical hurdles faced throughout the process. Jacobs outlines significant milestones, such as the various routes considered, the engineering innovations required for subaqueous tunnels, and the eventual decisions that led to the project’s realization. Additionally, he explains the construction methodologies employed, including the use of hydraulic shields for tunneling and the various materials and methods used to ensure stability under the challenging geological conditions of the riverbeds and urban infrastructure. Overall, this work illustrates the intricate planning and execution required to achieve a monumental engineering feat in railway transportation. (This is an automatically generated summary.)
