ALTERNATIVE CONCEPTS FOR UNDERGROUND RAPID TRANSIT SYSTEMS. VOLUME II: SUPPORTING STUDIES. B. PRESSURE PULSE ANALYSIS

The objective of the study was to determine if construction costs and operating energy requirements of future high-performance underground rapid rail systems can be decreased while maintaining or improving service. This part B of Volume II contains all of the basic information of the pressure pulse analyses that were performed on double-track tunnels and intervented pairs of single-track tunnels.
