Critical Rail Infrastructure Protection

The protection of critical rail infrastructure typically encompasses several layers, including static deterrents such as fences, signs and gates, as well as dynamic deterrents such as security patrols. Additionally, CCTV affords both a physical deterrent by observable placement, as well as a dynamic deterrent by means of awareness through observation. However, CCTV has its limitations due to the need for lighting the area of observation and the effects of weather such as fog and/or smoke. As well as the additional requirement for an operator to watch the video output and become aware of any intrusion or obstruction.

On the other hand, thermal imaging with integrated automatic incident detection (AID) can provide 24/7 automatic detection and awareness regardless of conditions. Initiating an alert when necessary to facilitate preventative or corrective measures. With the intention of avoiding impact, track interruption or damage to property.

FLIR Thermal Detection Solutions

Armitage Group as a FLIR Premium Partner, provides a range of thermal detection solutions for rail. Covering a range of applications with automatic incident detection to protect infrastructure, facilities and rolling stock.

FLIR ThermiBot2

ThermiBot2 combines best-in-class thermal imaging technology with advanced video analytics for improved rail tunnel safety. Intelligent thermal imaging automatically detects intruders in tunnels without triggering false alarms due to passing trains. ThermiBot2 also quickly detects early signs of fire. A rugged stainless-steel housing protects ThermiBot2 from harsh environments and allows it to maintain a clear image in challenging conditions.

Detecting Intrusions

ThermiBot2 improves tunnel safety by quickly detecting intrusions throughout rail tunnels. Thermal technology helps by alerting operators to potential vandals, allowing professionals to intervene before an accident occurs or costly equipment is destroyed.

Active Train Filtering

Using a dedicated algorithm, ThermiBot2 reduces false alarms by actively filtering out the motion of passing trains, while still detecting intrusions within tunnels. It can also be used as a dedicated train detection system with a very low false alarm rate.

Early Fire Detection

Thermal imaging allows the ThermiBot2 to recognize fires in their earliest stages. Intelligent video analytics can recognise a rapid rise in temperature and alert operators to signs of an impending fire.

TrafiSense2

TrafiSense2 is an integrated thermal sensor and detector for level crossing safety. Intelligent algorithms immediately alert operators when the TrafiSense2 detects objects stuck on the level crossing, increasing the overall safety of pedestrians and commuters. Thermal technology allows the TrafiSense2 to operate 24/7 and in any weather condition without the need for visible light illumination.

Safe Passage

When crossing barriers are open and no train is approaching, TrafiSense2 uses internal algorithms to detect stationary objects on the level crossing. If the object does not move in a preconfigured amount of time, TrafiSense2 alerts operators to intervene before an accident occurs.

Immediate Verification

When a train is approaching—and time is of the essence—TrafiSense2 immediately verifies that the level crossing is clear, and reports back to the control room in case of problems, which allows operators to quickly react to the potential threat.

Reliable Thermal Detection

Because FLIR thermal technology sees heat, rather than visible light, TrafiSense2 has the power to detect the presence of objects, pedestrians, and vehicles in low visibility environments, including total darkness, glaring light, and light fog.

Proven Application

Belgian rail infrastructure management company, Infrabel, uses FLIR thermal imaging cameras to detect people walking on the tracks. Where in 2018 there was 768 intruder instances, which caused 139,000 minutes of delay. Infrabel uses 30 FLIR thermal imaging cameras to look for intruders inside the North-South railway tunnels. Upon detection, an alarm is activated and a control room operator is warned of oncoming danger.

The system uses advanced detection algorithms in order to accurately detect people without being triggered by unwanted objects like small animals or passing trains. Infrabel put forward a demanding requirement of 99% detection accuracy, which the FLIR cameras have been able to achieve.

Rail Infrastructure Applications

From platforms to crossings, thermal imaging can provide an awareness, detection and protection solution for a range of rail infrastructure.
