Abstract: The present invention is directed to a train detection system for detecting the velocity, presence, and direction of a railroad car which may be utilized in existing railroad crossing installations. The train detection system is suitable for self-testing of its components and if an anomaly has been detected, the train detection system is capable of placing the system in a fail-safe state. The train detection system of the present invention is also capable of constant communication between the sensor of said system and the implementing device of the train detection system via a wireless link.

Abstract: A railroad maintenance-of-way personnel warning system and method therefor provides advanced detecting and warning of oncoming trains encroaching the construction area. Magnetometer sensors detect an oncoming train whereby a warning signal is transmitted to a receiver unit at the construction zone. Warning alarms including a flashing light and siren horn are thereby activated to indicate the imminent danger whereupon the construction personnel may take cautionary and evasive action in sufficient time to avoid mishap.

Abstract: A flexible gate is disclosed which comprises a plurality of segments. The segments may be connected by at least one coupling. When the flexible gate is acted on by a force, the flexible gate may flex. When the force is no longer present, the flexible gate may return to a substantially straight position. The segments may be removed or added as needed to repair broken segments or to adjust the length of the flexible gate.

Abstract: A railroad maintenance-of-way personnel warning system and method therefor provides advanced detection and warning of oncoming trains encroaching the construction area. Magnetometer sensors detect an oncoming train whereby a waning signal is transmitted to a receiver unit at the construction zone. Warning alarms including a flashing light and siren horn are thereby activated to indicate the imminent danger such whereupon the construction personnel may take precautionary and evasive action in sufficient time to avoid mishap.

Abstract: A railroad crossing traffic warning system for alerting a motorist approaching a railroad crossing to the presence of an oncoming train. The system comprises a series of magnetometer sensor probes buried in the right-of way adjacent to a railroad track at predetermined distances from the railroad crossing. These sensors provide a signal to a controller unit when the presence of a train is sensed. The controller unit first determines the speed at which the oncoming train is traveling and the time it will take for the train to reach the crossing and then activates an improved warning apparatus at a predetermined amount of time before the train reaches the crossing.
