STATION CONSTRUCTION AND METHODOF HANDLING TRAFFIC.

Specification of Letters Patent.

Patented Jan. 21, 1913.

Application filed October 18, 1911. Serial No. 655,368.

To all whom it may concern:

Be it known that I, ALPHONSUS L. DRUM, a citizen of the United States, residing at Highland Park, in the county of Lake and State of Illinois, have invented certain new and useful Improvements in Station Construction and Methods of Handling Trafiic, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to station construe tion and methods of handling the trafiic therein, and with respect to the more specific features thereof, the express stations of a four-track railway system and methods of handling the passengers in loading and unloading the cars.

One of the objects of the present invention is to provide a simple and practical arrangement of station platforms, entrances, and exits whereby the passengers may enter and leave the station quickly and without interfering.

Another object is to provide an arrangement of station platforms that may be quickly changed from loading to unloading platforms in order better to handle the traffic passing therethrough according to the direction of the heavier traffic due to the time of day.

A further object is to provide an efficient method of handling passengers entering or leaving trains and stations.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction herein after set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, wherein is shown one of various possible embodiments of this invention, Figure 1 is a plan view, partially diagrammatic, showing the arrangement of an express station and tracks of a four-track railway system. Fig. 2 is an enlarged view of a portion of Fig. 1 showing a slight difierence in arrangement of entrances and exits to accommodate better the traffic which is heavier in a direction opposite to that as provided. for by the arrangement shown in Fig. 1.

Similar reference characters refer to sim ilar parts throughout the several views of the drawings. 1

For convenience and better illustrating the nature of the invention, it will be hereinafter described with relation to a fourtrack subway system, although it is, of course, to be understood that with slight modifications the same invention may be applied to elevatedrailroads or suburban steam railroads.

In the usual four-track subway system four or five local stat-ions are arranged intermediate the express stations, which latter are substantially a mile and a half or two miles apart. If a person boards a local train at one of the intermediate stations and is traveling a considerable distance, on arriving at the next express station he changes to an express train and travels the remaining distance or to the express station nearest to his destination thereon, when he again boards a local train until he arrives at the proper station. In the subways as now arranged there is much confusion at the ex press stations in the loading and unloading of passengers from the same side of the express train and transferring them to and from local trains at the opposite side of the platform. This also causes some delay as time is first required to unload, through the waiting crowd, the passengers arriving at their destination or desiring to change to a local train usually going in the same direction, and then to load the waiting passengers who have gotten off of a local train from preceding intermediate stations. By the herein described arrangement of tracks and platforms this confusion is avoided and time saved by simultaneously loading and unloading the cars from opposite sides thereof. From observation, it has been noted that the average time for loading an express train during the rush hours is substantially seventy seconds, which, together with the time taken for the train to pull into the station, requires practically two minutes for each train to pass a-station. If, however, the station is so located, that is, halfway between uptown and downtown where there is less unloading, this time will, of course, be reduced thirty or forty seconds. It has been found by experience, however, that loading the train from one side while unloading from the opposite side saves thirty to forty seconds, thus reducing the average total time to sub stantially a minute and a half, thereby permittingforty trains instead of thirty trains to pass a station per hour, or increasing the capacity of the express track substantially Referring now to the drawings in detail, particularly Fig. 1, let it be assumed that the tracks run beneath a main street extending in the direction of the length of the city and that the station shown is located downtown at a cross street. The platform entrances and exits are arranged to accommodate the morning traflic which is heavier in a downtown direction-as indicated by the arrow T. As the tracks approach the sta- 7 tion they diverge to provide intermediate the local tracks space for three island platforms A, B and C, respectively, the two outer tracks being on which the trains run in the directions as indicated, while the inner tracks are for the express trains. These platforms are connected by stairways with mezzanine or transverse platforms 1 and 2 positioned above the tracks and running in the direction of the cross street. The platform 1 may be considered as the entrance platform and is provided with two entering stairways 3, near its opposite ends. Two exits 4: may also be provided, if preferred, although it may be desired to confine the exit of the passengers to exits 5 leading from the platform 2 at the opposite side of the cross street. The platform 1 is provided with ticket windows 6 near the entrances past which the. passengers must go to board the trains. A railing 7 divides the plat-form 1 longitudinally and is provided at the head of each stairway leading to platforms A, B, and C with swinging gates 8, 9 and 10, respectively. As herein shown in Fig. 1, the gates 8 and 10 are practically closed, a small space being provided to permit the few passengers wishing to take a local train to a closely adjacent station to enter the platforms A and G directly. The sections of the gates 8, 9 and 10 are freely movable so that they may be easily and quickly changed from one to another of the positions shown. When the gates are arranged in this position both stairways leading from the platforms A and C may be used as exits to accommodate people leaving the station, the number leaving being much greater than those entering. Swinging gates 11 and 12 are provided near the exits 4 for this purpose.

Referring now to Fig. 2, which shows the arrangement of the same station platforms for accommodating the evening trafiic which is heavier in an uptown direction, as indicated by the arrow T, it will be noted that at this time there will be more people entering the station than leaving. The two platforms A and C which in the morning were used for unloading trains are changed to loading platforms by opening the gates 8 and 10, and closing the gate 9 to the platform B. The platform B is used for unloading express trains only, there, of course, being comparatively few coming uptown from the the few remaining downtown stations and leaving at this station. The gates 11 and 12 are moved to the position indicated so that the exits 4 may be used as eutrances at this time. Changeable signs Entrance or Exit only should preferably be applied where necessary. Also signs in the cars should direct passengers to the discharging sides, although the latter could probably be dispensed with as people traveling the same route day after day soon learn the regulations while strangers naturally follow the crowd.

As the construction and arrangement of the parts of the station have been fully described, the operation and method of handling the traffic is substantially as follows: In the morning when the traflic is heavier in a downtown direction, the passengers are unloaded from both the downtown express and local trains onto the platform A, while the uptown express and local trains unload onto the platform C, both express trains loading from the platform B. the entrance to which is open at the gate 9, gates 8 and 10 being partially closed, Fig. 1, for the reasons above explained. All three platforms discharge their passengers to the transverse platform 2 hence by the exits 5 to the street. Some of the passengers may also leave by the exits 4 by using the wider part of the steps near the gates 8 and 10. In this way a large number of people may quickly leave the station without in any way interfering with the few people going uptown during the early rush hours. In the evening the. situation is reversed, that is. the heavier traffic is in an uptown direction and the platforms A and C are converted into loading platforms while the plat-form B is confined to the unloading of passengers from the express trains. The passengers may go direct through the gates 8 and 10 to the loading platforms where they enter either an express or a local train as desired. If any one should be going uptown, for example, on an express train and wished to take a local train, it is necessary for him to go up the stairs to the platform 2 and cross over to the platforms A or C, according to the direction in which he wishes to go.

As above stated, the present invention, is shown as applied to a subway system although it may be very easily applied to an elevated railroad by positioning the platforms 1 and 2 below the tracks instead of above.

It is thus seen that this invention provides a simple and practical arrangement of station platforms whereby the traffic may be quickly and efiiciently handled without confusion or interference between the entering and leaving passengers.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1.
