Many developing countries are building metro systems, which have encouraged economic growth in city centres but are proving enormously costly. This book forms an invaluable study of the arguments for and against metros, based on analyses of the advantages and problems encountered in several cities throughout the world. The authors consider how to overcome some of the difficulties, recognizing the crucial economic role of rail mass transit systems in large cities.
