DESIGN OF A HYBRID UNDERGROUND RAPID TRANSIT SYSTEM (HURTS)

A preliminary design for a high-speed underground mass transit system is developed to serve ten major cities of the Northeast Corridor from Boston, Massachusetts, to Washington, D.C. From estimates of national transportation needs, passenger demand for such a system would approach 80,000 passengers per hour during peak rush hour periods by 1980. The proposed network layout employs primary routes for high-speed cruise and spur routes for acceleration, deceleration and terminal link-ups. A typical train would incorporate up to 28 vehicles, each seating 40 passengers, and would travel in evacuated underground tubes with pneumatic propulsion providing thrust for acceleration at 6 ft/sec2 and electric linear induction motors providing thrust for high-speed cruise at 200 mph. The tunnel system would consist of a subsurface tunnel with a precast concrete liner. Within the concrete liner would be one-inch thick steel tubes enclosing the vehicles and guideway. The guideway would consist of continuously welded steel rail segments anchored in prestressed concrete ties. A preliminary cost analysis produced an initial capital cost for the entire HURTS network of $6.95 billion. Annual operational expense was estimated to be $839 million with annual passenger demand at 14.6 billion passenger miles, and cost per passenger mile would be 5.7 cents.
