Aseries of suggested designs for double-deck stations is thenpresented. One of them is reproduced in Fig. i. THE CONCLUSIONS The conclusions are: (1) The present subway, altliough carrying more passengersthan it was originally designed to handle, lacks sufficient pas-senger carrying capacity under the conditions that it is nowoperating to pay a fair return on the investinent and at the sametime allow for a suitable depreciation reserve. (2) The present subway is also defective in not having suffi-cient passenger carrying capacity to take care of the demands. FIG. 1—ONE PROPOSED ARRANGEMENT OF DOUBLE-DECKEDSTATION of transportation along its route during the two rush-hourperiods of the day; that is, the subway is lacking in what mightbe termed overload capacity. (3) The headway and therefore the capacity of the presentsubway is governed by the station headway; that is, thenumber of trains is limited by the number that can be passedthrough the limiting station. The capacity of future subwaysshould be limited only by the nimiber that can safely be passedover the tracks between stations. (4) The present rate of train movement of 30 trains perhour in one direction upon each track can be increased to 40trains per hour by a—Installing automatic closing door signals upon the cars ; b—Providing speed control signals auxiliary to the presentblock signal system at the approaches to the stations; c—Altering the cars to provide more doors in the sides ofeach car.
