Train Tracking Using Frauscher Axle Counters

Application Options:

In DC track circuit-activated crossings, the replacement of only the island circuits with axle counters 

  • Island circuits are the most challenging part of DC track circuit-based crossings, since they easily collect road salt and debris
  • In this application, only the island circuit (middle track section) is replaced with two Wheel Sensors RSR180 (TS 2 in figure below)

Full replacement of DC track circuits that activate crossing

  • Axle counters interface with existing crossing controllers using the optocoupler, relay or Ethernet outputs
  • The DC track circuits in the crossing are replaced for all track sections (TS 1, TS 2, TS 3 in figure below)

Switch Point Protection and Yard Automation 

Increasing Uptime, Reliability and Worker Safety

  • Use of wheel sensors and axle counters in years where hand-thrown switches and manual routing procedures are being utilised can improve efficiency and safety
  • The Frauscher Advanced Counter FAdCi system offers switch and flank protection, zero speed capability and handling of vehicle wheel rocking
  • Offers quick release of switches after traversing to route next train, provides flank protection to switches, and tracks axle counts within configurable track sections
  • Provides high uptime and availability in busy yard environments – increases safety as workers are not required on track for switching manoeuvres

Application Options:

For fully automated yard applications: 

  • The FAdCi is a vital, SIL 3 fail-safe axle counter, used in conjunction with the Wheel Sensor RSR180
  • FAdCi detects trains from zero speed to 50mph
  • Minimal maintenance is required 
  • The FAdC is also available, offering SIL 4 fail-safe protections and train detection from zero speed to 280mph

In switch point protection only solutions:

  • The Frauscher Wheel Sensor RSR110 is installed around each switch
  • Train detection can occur via analog signal. Digital output is also available
