First published in 1990 and based on sources not available for Paul Brickhill's earlier work, the book tells how on the night of March 24, 1944, seventy-six Allied POWs slid through a 350-foot tunnel and out of a high-security German prison camp, into history.
Mega structures takes a close look at some of the tallest, longest, and largest structures in the world. Each book lets the reader in on the challenges, dangers, and successes in building these colossal structures....
The true story of the construction of the historic Crozet railroad tunnel—as seen through the eyes of three Irish immigrant families who helped build it. In one of the greatest engineering feats of the time, Claudius Crozet led the completion of Virginia’s Blue Ridge Tunnel in 1858. More than a century and a half later, the tunnel stands as a National Historic Civil Engineering Landmark, but the stories and lives of those who built it are the true lasting triumph. Irish immigrants fleeing the Great Hunger poured into America resolved to find something to call their own. They would persevere through life in overcrowded shanties and years of blasting through rock to see the tunnel to completion. In this intriguing history, Mary E. Lyons follows three Irish families in their struggle to build Crozet’s famed tunnel—and their American dream. Includes photos and illustrations
This book seeks to deepen readers’ understanding of world history by investigating urbanization and the evolution of urban systems, as well as the urban world, from the perspective of historical analysis. The theoretical framework of the approach stems directly from space-economy, and, more generally, from location theory and the theory of urban systems. The author explores a certain logic to be found in world history, and argues that this logic is spatial (in terms of spatial inertia, spatial trends, attractive and repulsive forces, vector fields, etc.) rather than geographical (in terms of climate, precipitation, hydrography). Accordingly, the book puts forward a truly original vision of urban world history, one that will benefit economists, historians, regional scientists, and anyone with a healthy curiosity.
Still suffering the devastation of the Civil war that ended only ten years earlier, North Carolina shipped prison inmates from Raleigh to build the Mountain Division of the western North Carolina railroad. Some amazing and astonishing events occurred from 1875 through 1879 as this mountain railroad (3 miles straight-line distance, requiring 9+ miles of track) was pushed up the eastern continental divide. Six tunnels were excavated, from 89 to 1,800 feet long, each 15 feet tall. For open cuts, solid rock was cracked by dousing cold mountain water on roaring fires. The first use in the southeastern U.S. of a new product called Nobel's Blasting Oil (now called nitroglycerin!) was on the project. It was mixed with sawdust and corn meal, making nitroglycerin mash. A very heavy wood-burning locomotive was picked up off the tracks by the convicts and pushed several miles overland to the top of the mountain to help dig out the longest tunnel. The most common tool used was a flat rock held in the strong hands of the convicts to dig and spread dirt as they prepared the flat path needed to lay crossties for the rails. Tunnels, Nitro and Convicts condenses the incredible history of the most ambitious earth-moving, mountain-conquering project in the United States as of the 1870s into an engaging, easy-to-read story. The fascinating and compelling intertwining of long dark caves, blasting and cracking of massive rocks, the first use of nitroglycerin in the southeastern United States, and pushing a big locomotive several miles through the woods up a mountain ... all by hundreds of convicts who worked under severe conditions with the most basic tools ... makes this true account of post-civil war railroad history a story you must read!

The Tunnel Engineering Handbook, Second Edition provides, in a single convenient volume, comprehensive coverage of the state of the art in the design, construction, and rehabilitation of tunnels. It brings together essential information on all the principal classifications of tunnels, including soft ground, hard rock, immersed tube and cut-and-cover, with comparisons of their relative advantages and suitability. The broad coverage found in the Tunnel Engineering Handbook enables engineers to address such critical questions as how tunnels are planned and laid out, how the design of tunnels depends on site and ground conditions, and which types of tunnels and construction methods are best suited to different conditions. Written by the leading engineers in the fields, this second edition features major revisions from the first, including: * Complete updating of all chapters from the first edition * Seven completely new chapters covering tunnel stabilization and lining, difficult ground, deep shafts, water conveyance tunnels, small diameter tunnels, fire life safety, tunnel rehabilitation and tunnel construction contracting *New coverage of the modern philosophy and techniques of tunnel design and tunnel construction contracting The comprehensive coverage of the Tunnel Engineering Handbook makes it an essential resource for all practicing engineers engaged in the design of tunnels and underground construction. In addition, the book contains a wealth of information that government administrators and planners and transportation officials will use in the planning and management of tunnels.
