Infrastructure of America's Railway Systems (America's Infrastructure)

This book explores eight railroads and subways that are lifelines for transportation in the U.S., but are overloaded and often falling apart. Whether its Bostons T, Washington D.C.s Metro, the crescent Corridor railroad route, or a Desert Line railroad running from the U.S. into Mexico, these pieces of infrastructure are very important to the entire country, but need emergency repairs and expansion right now.
