摘要

PROBLEM TO BE SOLVED: To provide a train in formation for high-speed running capable of securing a spacious passenger space without impairing the reducing effect of fine pressure air waves. SOLUTION: The car body is furnished at the head part Z1 with section area increasing regions Z11, Z13 in front and in the rear in which the section area varies incrementally toward the rear of the body. Another section area increasing region Z12 as intermediate region having a smaller section area increasing rate than the front region Z11 and the rear region Z13 is provided between the two regions. The general part Z2 is composed of a front portion Z21 continued to the tail of the forefront part Z21 and having an approximately uniform section area and a rear portion Z22 having a greater body height and body width than the front portion and having approximately the same body height and body width as the following car. The head part Z1 is shaped so that the body width gradually increases linearly from the head toward the general part in the direction fore and aft of the body. COPYRIGHT: (C)2004,JPO
