LXVIII, Sept. 1910, The New York Tunnel Extension of the Pennsylvania Railroad, The Terminal Station - West by Benjamin Franklin Cresson is a technical document explaining the building of the Pennsylvania Railroad's New York Tunnel Extension during the early 1900s. The publication highlights the detailed engineering work involved in expanding the railway system, particularly concentrating on the west section of the terminal station describing the strategies and challenges of digging and construction in a busy city setting. Cresson goes into great detail about the project management techniques, material usage, and the precautions necessary to prevent damage to neighborhood buildings and train lines during construction, providing a technical glimpse into the massive scale of the project.
