摘要： A wayside signal for a railway includes a plurality of light emitting diodes housed in a housing. The light emitting diodes output indication signals. Further, the light emitting diodes are configured on a first circuit board which is thermally coupled to the housing. The housing may also include heat sink fins to dissipate heat generated by the light emitting diodes and associated driving circuitry for driving the light emitting diodes also contained within the housing. An additional light emitting diode may also be contained within the housing to point in an opposite direction than the indication signal light emitting diodes, which additional light emitting diode may be formed on a second circuit board with the driving circuitry. The additional light emitting diode provides an indication to anyone behind the wayside signal as to the indication of the wayside signal. The wayside signal is further optimized for thermal efficiency and to be sealed against the elements. In regard to thermal efficiency, the first circuit board may be metal clad and the housing may be formed of black anodized aluminum. Also, a plastic insulator may be attached to the housing and covered with a lamp base. The lamp base may be configured to be inserted into a conventional socket for a wayside signal, so that the wayside signal of the present invention can be utilized with existing circuitry.

摘要： A device for monitoring the passage of a train traveling through a rail way crossing, said device including a first and second sensors for sensing the presence of the train on a rail track when the train is in proximity to the sensors, said first and second sensors positioned adjacent the track, first and second processors opperatively coupled to the first and second sensors, respectively, the processors adapted to monitor the sensors and determine the speed and direction of the train when the train passes the sensors. The device also includes a signal positioned adjacent the crossing for signaling the public that a train is about to enter the rail way crossing, and a third processor operatively coupled to the signal and operatively coupled to the first and second processors, the third processor adapted to activate the signal when the train is within a predetermined time interval from entering the crossing.
