<p><P>PROBLEM TO BE SOLVED: To provide a high-speed underground railway which allows the operation of either a high-speed low-slung train or a linear motor train, which halves its cost in underground railway construction in an urban area. <P>SOLUTION: A small-bore large-depth tunnel is made with a straight wide-gauge rail from a ground station in a public domain. It goes down at the same gradient, and includes up sections, horizontal sections, and sections between ground stations at the same intervals. Down acceleration/deceleration sections are made regenerative power generation sections, and the horizontal sections are made high-speed inertial operation sections, and regenerated power is returned and synthesized with that of a gravitational generator by means of a balance having a pressure load device of output corresponding to the number of trains driven with power via two or more transformation units to increase an amount of power generation and feed power again. In this way, a high-speed subway is made in a large-depth small-bore tunnel with a straight railway of a single track and a double track in a structure covering the most of power for use. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
