Real-time rail temperature & GPS speed sensing
Rail temperature monitoring for safer slow-order decisions

The Gap
Without rail-level temperature monitoring, operators often rely on ambient temperature as a proxy, which may not reflect actual track conditions. Excessive rail heat can contribute to expansion, buckling risk, and slow orders, while extreme cold can increase rail fracture risk.
Apollo RailTemp addresses this gap through continuous rail temperature measurement, GPS-linked positioning, and in-cab alerts, helping rail operators and maintenance teams make more informed slow-order decisions and improve thermal risk visibility.
Give operators and maintenance teams rail-level temperature data to support slow-order decisions, corridor monitoring, and earlier response to heat or cold-related risk.
Display rail temperature and speed data directly to the operator for timely response
Link temperature readings to locations for corridor-level thermal risk visibility
Support slow-order decisions using measured rail temperature instead of ambient estimates alone


Bring rail temperature, GPS-linked speed, and alert context together in a rugged onboard unit designed for immediate operator decisions.

How it works
Measure left and right rail temperatures continuously using in-service mounted sensors
Calculate real-time train speed using onboard GPS
Assess temperature against thresholds to detect buckling and fracture risks
Display live temperature and speed on the onboard unit for immediate slow-order decisions
