This is the story of a project that took 35 years to complete. It was clear in the 1860s that building railway tunnels under the Hudson River, from Manhattan to New Jersey, would bring significant benefits in convenience and journey tine compared with ferries. Work started in 1873 - but it was 1908 before trains started to run, through tunnels still used today by the PATH rail system.
This book tels the story of the construction, with long interruptions for legal, safety and financial reasons. While there is a focus on the use of narrow gauge railways, the text and illustrations combine to show the challenges of a major tunneling venture over a century ago.
