The present invention relates generally to railroad crossing alert and safety systems and, more particularly, to an indicator for railroad crossings which indicates the speed of an oncoming train.
Automobile accidents are among the leading causes of death in the United States. Many thousands of railroad crossings intersecting with vehicle roadways exist and the importance of providing adequate and reliable information regarding an oncoming train is crucial to protect motorists. Automobiles struck by trains at railroad crossings usually result in higher mortality rates than other vehicular accidents. These accidents are also among the easiest to prevent. Typically, railroad crossing guards are activated via train detectors and serve as an effective means by which to prevent these accidents. Conventional railroad crossing warning systems include a crossbuck, warning bells, flashing lights, and automatic crossing gates. More complicated safety systems also exist from automated warning and access systems to satellite alert systems. These various attempts to provide warning and alert systems to motorists in close proximity to a railroad crossing with an oncoming train can be seen by reference to several U.S. Patents.
U.S. Patent, issued in the name of Shirkey et al., describes a wireless train proximity alert system generally comprising a plurality of transceivers which are in communication with one (1) another that provides a constant warning signal to vehicles approaching a railroad crossing when a train is approaching. U.S. Pat. No. 5,890,682, issued in the name of Welk, describes a railway crossing collision avoidance system generally comprising a signaling device and GPS receiver that alerts a vehicle in the vicinity of a railroad crossing to an approaching train. U.S. Pat. No. 5,954,299, issued in the name of Pace, describes a railroad crossing traffic warning system apparatus and method therefore generally comprising a series of magnetometer sensor probes buried adjacent to a railroad track that provides an alert to a motorist approaching a railroad crossing to the presence of an oncoming train. U.S. Pat. No. 6,179,252, issued in the name of Roop et al., describes an intelligent rail crossing control system and train tracking system generally comprising an internal controller that receives digital information regarding a train such as, direction speed, length, and identity. U.S. Pat. No. 6,241,197, issued in the name of Harland, describes an automated rail way crossing generally comprising a series of sensors that monitors the passage of a train travelling though a railroad crossing. U.S. Pat. No. 6,572,056, issued in the name of Berry et al., describes a method and apparatus for uniform time warning of railroad trains that controls the approach of an oncoming train such that a uniform warning time is ensured.
These systems can be expensive and require regular maintenance to ensure effectiveness. Many railroad crossings in less populated areas have no warning or alert systems at all or simply employ a standard crossbuck. Many motorists still attempt to beat such systems by either driving around the gates or by ignoring the crossing guard indicators. If these motorists simply knew this speed of the oncoming train, they would think twice about trying to “beat” them across the track. However, many motorists are poor judges of speed or may not have an actual view of the train due to limited line of sight position.
While these devices fulfill their respective, particular objectives, each of these references suffers from one (1) or more of the aforementioned disadvantages. Accordingly, the need has arisen for an effective solution to this problem that will help to prevent drivers from taking these risks. The development of the present invention substantially departs from the conventional solutions and in doing so fulfills this need.
In view of the foregoing references, the inventor recognized the aforementioned inherent problems and observed that there is a need for a simple and practical means to provide information related to speed of an oncoming train to roadway vehicles approaching a railroad crossing to discourage a motorist from attempting to cross before the train arrives and thus, the object of the present invention is to solve the aforementioned disadvantages and provide for this need.
To achieve the above objectives, it is an object of the present invention to provide a speed indication device for approaching trains at railroad crossings that provides a means for displaying the speed of an approaching train on a conventional railroad crossing, thereby preventing motorists from trying to outrun oncoming trains and causing accidents.
Another object of the speed indication device for approaching trains at railroad crossings is to provide a system comprises a digital speed display, a speed warning sign, a control enclosure, a power drop, a speed detection beam, a power supply, a rechargeable battery, a speed detection circuit, a speed detection means, and a digital display driver. The speed warning sign provides various visual indicia to draw the attention of a motorist to the digital speed display which indicates the speed of an approaching train using the appropriate unit of measurement per local requirements. Thus with a conventional pair of crossing lights energized and the speed of an oncoming train displayed upon the digital speed display, motorists would be less likely to attempt to “beat” the train across the railroad crossing. After the train has passed, the system continuously monitors the train track for other trains.
Yet still another object of the speed indication device for approaching trains at railroad crossings is to provide a speed warning sign comprising warning indicia, a speed detection means that projects a speed detection beam, and a digital display that provides visual indication of the speed of an oncoming train approaching the railroad crossing.
Yet still another object of the speed indication device for approaching trains at railroad crossings is to provide a control enclosure comprising a speed detection circuit that receives digital information from the speed detection means, processes the information and transmits an output signal to the digital speed display.
Yet still another object of the speed indication device for approaching trains at railroad crossings is to provide a system that easily attaches to any standard railroad crossing warning post or crossing gate via a plurality of corresponding couplings with associated
Yet still another object of the speed indication device for approaching trains at railroad crossings is to provide a method of utilizing the device that provides dangerous train crossings and additional means to alert motorists to the potential dangers of a last second crossing in a manner which is quick, easy, and effective.
Further objects and advantages of the speed indication device for approaching trains at railroad crossings will become apparent from a consideration of the drawings and ensuing description.

The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items.
The present invention describes a speed indication device for approaching trains at railroad crossings (herein described as the “system”) 10, which provides a means for displaying the speed of an approaching train thereon the conventional railroad crossing pole 30, thereby preventing motorists from trying to outrun oncoming trains and causing accidents. Said system 10 comprises a digital speed display 45, a speed warning sign 50, a control enclosure 55, a power drop 60, a speed detection beam 70, a power supply 75, a rechargeable battery 80, a speed detection circuit 85, a speed detection means 90, and a digital display driver 95. The speed warning sign 50 provides all indication of the functionality of the digital speed display 45 and would indicate the speed of an approaching train in the pertinent miles per hour or kilometer per hour as per local requirements. Thus with a conventional pair of crossing lights 40 energized and a speed displayed upon the digital speed display 45, motorists would be less likely to “beat” the train across the railroad crossing 15. After the train has passed, the system 10 continues monitoring the train track 20 for other trains and thus operates in a continuous manner.
