Connected Crossing

Remotely Monitor Train Control Signals and Grade Crossing Safety Lights

Until now there has been no economically viable solution to automatically test if train control signal and grade crossing safety lights are fully illuminating and oriented in a viewable position. TekTracking is changing that. Our Connected Crossing contains multiple diverse sensors to measure, compare, and verify all aspects of proper crossing operation.  We monitor proper operation of the grade crossing’s electronic controller, relays, track circuits and the viewability of the crossing gates and warning lights from the motorist’s point of view.

How Safety Light Monitor (SLM) Works?

TekTracking’s patent-pending safety light monitor (SLM) provides an automatic method for remote sensing, collecting, analyzing, and reporting real time data reflecting performance of safety lights, including train control signal lights and grade crossing warning lights. SLM, consisting of sensor system and image processing with data analytics, will automatically generate and communicate maintenance alerts if lights malfunction.

The SLM utilizes multiple sensors to monitor the integrity of a safety light from the perspective of the external viewer of the light.  The data and images captured by the SLM are communicated over a private data radio network to a network edge concentrator/router (Edge Processor), typically located in a remote equipment house. Image and condition analysis are performed by an edge processor algorithm, and all relevant events are communicated to the enterprise network for further action and response.

Key Benefits

  •  Ensure and enhance the reliability of signal lights
  •  Take timely action with the help of accurate condition reported
  •  Cut time and cost spent on manual monitoring of signal lights

Gate Light Monitor (GLM)

This device mounts on the crossing gate pole and monitors the gate position while in transition. Once the gate is activated, the GLM automatically detects the two flashing lights and the single steady light on the gates. If any one light does not operate per specification, then the GLM will generate an alarm message to the signal maintainer.

Connected Crossing View 360 (CCV-360)

CC-360 is our omni-directional camera capable of viewing the entirety of the crossing, including the train tracks as well as the highway traffic. All gates can be observed in operation from the CC-360. CC-360 is also ideal for detecting trespassers or other suspicious activity near the crossing.

Edge Image Processor (EIP)

The EIP is the brain on the edge of the network used to interpret all images generated by SLM/GLM/CC-360. We employ machine learning technology within the EIP, and this allows local interpretation of video images for the purpose of detecting and alarming on anomalies.

SA380-TX Digital Storage Oscilloscope

The SA380-TX provides capture of discrete digital events and analog waveforms from track circuits, relays, motors, etc. The status of the collected information is communicated over the network to Centrix. Centrix compares data over time and develops predictive analytics results to alert maintainers of imminent device failure.

SLX serial port interpreter

The SLX is used to monitor the vital crossing processor. Many modern crossing processors store operational data that can only be accessed via the maintainer’s laptop. The SLX mimics the laptop communication protocol and automatically pulls data from the vital controller. The data is then directed over the railroad’s network to CENTRIX. Centrix compares data over time and develops predictive analytics results to alert maintainers of imminent device failure.


Bus bar monitoring device continuously measures electrical resistance to ground from up to five separate power sources.


CENTRIX collects field data and analyzes the data for indications of anomalous performance. CENTRIX is proven to predict failures of critical railway components including machine motors, track circuits, and proper timing of discrete contacts.
