abstract="Speedup of passenger services on narrow-gauge main lines of Japanese National Railways is complicated by curvature, stopping distance requirements and light axle loads. Instead of track changes, JNR has adopted new rolling stock technology with electric cars of low center of gravity and pendulum suspensions which can negotiate fairly sharp curves at good speed. Without new equipment, JNR has an analytical method for appraising speedup--identifying the factors involved, confirming the safety and comfort of the projected schedules, and assuring against excessive expenditures that may be involved.<p />",
