Wireless Railway Crossing ('WRX') System - Implementation

Because the SafeZone WRX System is completely modular and wireless approach, it makes spec'ing out a site as simple as laying out the proposed placement of detection and warning devices on a site map or an aerial or satellite photo.

Issues relating to trenching, underground ducting and access to mains power simply don't apply. With WRX, the primary considerations are:

  • what train detection and/or warning devices are already (if any) installed; and if none, 
  • what configuration is required for the Wireless Detection Radar system, and 
  • what type and what number of SafeZone warning devices are required to address site specific issues such as visibility on approach, local speed limits, side access roads, etc
  • what issues there are with relation to solar radiation (ie sun) arising from shadowing by trees, hills, other structures, etc 

To understand the modular nature of a SafeZone WRX System, the following typical examples are given:

1 - A 'Full Visual Warning System' type deployment:

  • wireless Train Detection Radar (TDR) units (typically 4; ie 2 at the corssing, 2 on the rail approaches to the crossing, with the units farthest from the crossing detecting trains approaching in order to activate the system, and the pair closest the crossing detecting trains leaving the crossing in order to deactivate the system); and
  • wireless Active Wig-Wags (RX-5 type signs) at the crossing, facing on-coming road vehicles; and
  • wireless Active Advance Warning Signs (RX-11-type signs) on the approaches to the crossing (typically 300-400 metres in advance, depending on visibility and speed limit on the approaches); and
  • wireless In-Road Alert Devices (IRADs) typically every 6-10 metres apart, down the road lane markers, 300-400 metres in advance of the crossing, stopping at the position of the AAWSs; and
  • a wireless Alert Device Controller (ADC) that integrates all system elements (one per site)

Optionally, aSafeZone WRX System can be interfaced to an existing train detection system, eg, one used to activate existing Wig-Wags at the crossing (ie supplied by others). 

2 - A wireless 'advance visual warning' solution, comprising:

  • wireless Active Wig-Wags (RX-5 type signs) at the crossing, as above; and/or
  • wireless Active Advance Warning Signs (RX-11-type signs), as above; and/or 
  • wireless In-Road Alert Devices (IRADs), as above; and
  • a wireless Alert Device Controller (ADC) that integrates all system elements (one per site)

Because SafeZone WRX is a modular system, any combination of wireless detection, wireless advance roadside and/or wireless in-road warning elements can be included, as required.

Benefits:

  • speedier installation than traditional hard-wired systems
  • modular approach allows customisation to suit site-specific needs
  • overall lower cost - as little as 10% of a traditional boom gate solution, yet far more effective at delivering more obvious advance warnings
  • expandable: add IRADs, additional AAWSs or WiWAGs as required at any time
