Abstract (en)
[origin: WO2020257824A1] The present disclosure includes a portable rail safety system configured to determine a position of a rail switch. The rail safety system may include a rail switch detector, one or more rail switch beacons, a work block marker, a personal alert device, a collision avoidance system or combination thereof. In some aspects rail switch detector includes a first detector configured to be positioned between switch rails of a rail track and having a body, a first sensor coupled to the body and configured to detect a first switch rail tip of the switch rails, and a controller configured to calculate a first distance between the first sensor and the first switch rail tip and based on the first distance, determine a position of the switch rails between a first position and a second position.
