Along the bottom of this tube is laid a railroad track and on this track runs a spacious car, richly upholstered, well lighted and with plenty of space for exits. The track is single and level; it is not cold in winter. It will be delightfully cool in summer.

A car mounted on a track is moved much easier than a boat upon the water, because ! the vessel encounters great resistance in displacing ¡ the water, while the car merely has to overcome the friction of the wheels, which is only one four -hundredth part of its weight. Therefore only a small air pressure is required to drive a pneumatic car with a high velocity. 16 ページ - A myth or a humbug it has hitherto been called by everybody who has been excluded from its interior; but hereafter the incredulous public can have the opportunity of examining the undertaking and judging of its merits. 17 ページ - RAII.WAY. oil-cloth of a pretty pattern, the walls hung with pictures, an expensive clock in the centre, elaborate chandeliers along the walls, comfortable settees at each side, and at the further end a space railed off for the occupancy of the ladies, with one of Chickering's grand pianos for their amusement while waiting for the train. 13 ページ - When the tunnel is opened to the public, it will be no dirty hole in the ground the people will be invited to enter, but a handsome subterranean avenue, through which they may be rapidly transported to their homes up-town. 14 ページ - Even as we write, a comfortable passenger-car is running smoothly and safely between Warren and Murray streets, demonstrating beyond contradiction that it is only a question of time and money to give us rapid and comfortable transportation from the Battery to Harlem and back again. |
