Book Description
Describing and detailing the boring of major railroad tunnels throughout Canada, the United States, and Mexico, this book covers the period from the creation of Virginia's Blue Ridge Tunnel in the 1850s to Copper Canyon's Continental and El Descanso tunnels in the early 1960s. Other notable tunnels featured here include Massachusetts' notoriously expensive and slow-progressing Hoosac Tunnel; Colorado's rail and water Moffat Tunnel; Montana's Flathead Tunnel; and several major tunnels along the Canadian Pacific's main line. In addition to providing details on the tunnels, the author considers the reasons they were created, their engineers, and their use. The book includes more than 50 period and contemporary photos. A glossary explains concepts related to railroad construction and maintenance.
