Wayside rolling stock diagnostics and monitoring AKRO
AKRO is a comprehensive solution for an intelligent rolling stock diagnostics and monitoring system
- Modular diagnostic equipment (wayside and station equipment)
- Flexible and multi-level centralization for monitoring
HBD – Hot Box Detection
HWD – Hot Wheel Detection
DED – Dragging Equipment Detection
AVI – Automatic Vehicle Identification
WDD – Wheel Defect Detection
WIM – Weighing In Motion
AKRO basic function
Hot Box Detection (HBD) function is used for checking the axle box heating due to bearing failure.
Bearing defects and brake system failures are the most common rolling stock failures. Bearing defects are dangerous as they cause rapid worsening of a wheelset which may lead to axle journal brake and derailment of the train.
Economic losses from such incidents can reach millions of euros.
Hot Wheel Detection (HWD) function is used for checking Wheel Disk heating due to jammed brake pads.
Another rolling stock issue is a brake system failure (jamming or wearing out of the pads). If the brake pads are jammed, they wear out quickly and increase fuel/energy consumption for traction. In some cases, significant heating of the wheel rim can be fire-hazardous.
AKRO allows you to measure the temperature in the rim area, the area that heats up the most when the brakes are stuck.

AKRO-B software
AKRO-B allows the operator to get:
- Information about trains (in real time or those that have passed earlier)
- Status of check-point equipment
Possibility to view all measured temperature profiles (axle boxes and wheel disks).
Temperature profiles include both temperature data and signals from wheel sensors. This combination allows to quickly and adequately evaluate the primary measurement data if necessary.
AKRO-C centralization software
Operational information about the situation, notifications of warnings and alarms:
- Information about the status of rolling stock in trains that have passed through checkpoints
- Details of warnings and alarms of each train passage
- Other information about train passages

Access to detailed information about the condition of the train and AKRO equipment at checkpoints:

Date and time of train passing

Number of rolling stock units/axles in the train

Train warnings and alarms

Condition of the AKRO checkpoint equipment
Monitoring of rolling stock condition changes in dynamics:
- Computer-aided analysis of axle box heating
- Computer-aided analysis of wheel heating
- Computer-aided analysis of other parameters (programmable)
It allows you to visualize temperature changes in absolute values, percentages and coefficients in the form of graphs
