Detection of track occupancy with GSM‑R radio analysis

Tracks at an industrial site in the evening sun

Transparency on the track:
AI-based analysis of GSM-R switching radio

challenge

Service facilities (siding) of the national railway infrastructure lack digital systems across the board which record the actual usage status of the facilities. Dispatchers on site coordinate directly with train drivers whether a track is occupied — via GSM-R shunting radio. However, these conversations are not recorded or evaluated. This results in information gaps, unused potential in capacity planning and cases of so-called black use, i.e. undeclared or unpaid use.

Our solution

As part of an innovation program, AMAI developed an AI-based solution that is able to analyze the GSM-R routing radio in real time and extract targeted operationally relevant information.

Thanks to standardized speech discipline in rail traffic — which clearly states information such as train numbers, track details or train driver identification — movements can be digitally traced without saving personal data. The solution is fully GDPR-compliant and fits seamlessly into existing operating processes.

What technology can do

Real-time analysis of radio calls between dispatchers and train drivers
Automatic extraction of relevant data such as track numbers, location information and train movements
No additional requirements for operating personnel: the system works completely passively
Instant anonymization: Personal data is never stored or processed

Benefits for network operators

Increased transparency about the use of service facilities
Reducing black use, which leads to additional income
Better predictability and utilization through precise data bases
Supporting strategic goals through digital capacity management
Data basis for further automation, e.g. in capacity management or scheduling

outlook

After successful validation of the prototype as part of the innovation program, the network operator is testing the roll-out at the operating sites and integration into group-wide capacity management. Thanks to its generic design, the system can also be used in ports, depots or factory railways.
