Grade Crossings

Improve reliability, safety, flexibility and uptime while decreasing maintenance costs using wheel sensors and axle counters

Operators responsible for grade crossings often face conflicting priorities - meeting stringent availability and safety requirements while managing budgetary constraints. Only a small percentage of grade crossings in North America are gated, leaving many thousands that are not wired for safety. In the case of crossings that are protected,  the most frequently used technology can become inoperable in harsh environmental conditions. In addition, tracks where a train does not pass over for several days can quickly build up rust, resulting in loss of shunt that can make the use of track circuits impossible.

Frauscher has a solution. Our axle counters can work alone or in conjunction with existing track circuits to improve crossing safety. While track circuit systems can struggle with low uptime and availability and high maintenance costs, axle counters provide a high level of reliability with minimal maintenance, even in the harshest of conditions.

Frauscher axle counters and wheel sensors provide a wide range of options for activating, deactivating or resetting grade crossing protection systems in a way that ensures safety and high availability. Our proven technology can indicate the direction from which a train is approaching, and provide clear/occupied status information. This reduces the overall complexity and costs typically associated with grade crossings.

These benefits are provided with precision and reliability. In addition, the Frauscher Diagnostic System FDS has remote diagnostic, calibration and preventative maintenance capabilities. This proactive maintenance approach helps to reduce overall costs by maintaining uptime and allowing for more efficient allocation of resources.The overall system has a fixed maintenance cycle of two years.


Grade Crossing Control Systems

Train detection systems commonly used to protect grade crossings in North America can be negatively impacted by environmental factors such as snow, flooding, road salt and leaf accumulation, resulting in downtime and expensive maintenance. The Frauscher Advanced Counter FAdC is a vital, fail-safe SIL4 axle counter that is not affected by harsh conditions, and can detect trains up to 280 mph. It offers flexible design capabilities that can be configured with a vital relay or vital Ethernet interface, allowing seamless implementation and integration with existing infrastructure. The FAdC can either replace or be installed as an overlay to existing track circuits to protect crossings. In DC or AF track circuit based crossings, the FAdC can be implemented by replacing the island circuit alone, or by replacing both the island + approach. The addition of axle counter equipment does not alter track geometry, as the wheel sensors are clamped, not drilled, to the rail.


  • Wide range of options for activation, deactivationg or resetting crossing protection systems for high availability and safety
  • Significantly reduced maintenance (every two years)
  • Increased uptime by functioning in harsh environmental conditions

Axle Counters - FAdC 

The Frauscher Advanced Counter FAdC features functional modularity, flexible scalability and an Ethernet-based interface that allows a wide range of configurations. The software interface enables the FAdC to be integrated effectively into higher-level systems offering greater flexibility in terms of design and communications. System integrators and rail operators will benefit equally from these significant advantages.

The Frauscher Safe Ethernet (FSE) protocol empowers the operator to independently integrate the solution. It is easy and has simple logic. It eliminates proprietary software that is prohibitive in implementation efforts and costs. Frauscher provides training and complete support.

Wheel Sensors - RSR110

Our easily integrated and highly reliable wheel sensors help maximize uptime and achieve cost effective operation across a wide range of applications. The open interface eases implementation into new or existing systems, providing the flexibility needed to meet individual application requirements. The development and production of the entire sensor family RSR110 adheres to international standards, assuring optimum operation under all conditions.

The patented Frauscher rail claw, plug‑in connector cable, and automated adjustment procedure significantly reduce the effort required for assembly, disassembly or changing the location of a sensor. This provides significant savings, in terms of money as well as time.
