Stalker LIDAR RR
Precision Laser Speed & Distance Measurement
Designed Especially for Railroad UseLaser speed measurement with a range of 4,000 feet and 0.2 MPH sensitivity make the Stalker LIDAR RR the best choice for railroad applications.
When a major U.S. railroad asked Stalker Engineers for help with rail car speed issues, it was apparent that modification of our existing LIDAR’s controlling firmware was needed. “Speed” in the railroad sense is different from the automobile enforcement sense. What resulted is a speed measurement tool that is accurate to a 0.2 MPH - law enforcement only requires 2.0 MPH accuracy.
Moreover, the LIDAR RR can discriminate between closely spaced individual cars among groups of cars in settings that would be impossible for radar. It’s the ideal tool for loss prevention through speed control in the classification yard.Typical applications of the Stalker LIDAR RR:
- In Classification Yards
- Monitoring Line Speed
- Railroad Police Duty
- Speed Restriction Enforcement

Features of the Stalker LIDAR RR
- Monitor retarder exit and coupling speeds
- Measures distances to within 1/2 foot (0.15 meter)
- 0.2 MPH speed sensitivity
- Self Contained - Rechargeable battery operated
Features include:
- High powered optics
- Ergonomic, rechargeable battery handle provides better balance, which means less physical stress
- Integrated battery charger
- Time Distance Converter (TDC) for improved time/distance measurements
- Doppler Audio Tracking
Single-Shot and Continuous Tracking Modes
The LIDAR RR can be set in Single-Shot mode where the trigger is pressed and the unit locks on a single speed reading.
Or, the unit can be operated in tracking mode where the trigger is pressed and the unit takes continuous, real-time speed readings.
Doppler-Type Audio Tracking
In some instances, laser operators also operate radar, the LIDAR RR generates a continuous Doppler-type audio tone which correlates to the target speed. Just like the audio on a police radar, this audio is a substantial aid to understanding and building a target tracking history.
