Rail Fault Monitoring in Real-Time


01 / Predictive

NiMs allows for real-time monitoring of electrical conditions in both AC and DC environments. This allows for predictive maintenance, reducing MRO costs for railway operators.

02 / Scalable

Individual NiMs modules are installed across the railway network and communicate across existing infrastructure. This allows for cost-effective implementation of the NiMs solution.

03 / Data Collection

Voltage and current data is collected in real-time. This is displayed for each node across the railway network in NiMs software platform, allowing operators to identify exactly where a fault has occurred.




NiMs Global Pte Ltd (NiMs) is  headquartered in Singapore and has developed power line communication semiconductors, devices and systems that enable the transformation of the AC/DC electricity grid, specifically associated with trams and trains, into “smart” closed looped grids by transferring performance data to a central console and operations centre.  


We believe that creating an IoT platform for electrical railway networks can transform railway maintenance and repair. By leveraging real-time data, operators can reduce costs and minimize the occurence of railway faults that interrupt everyday travel.


NiMs leverages existing electrical networks to communicate data with operations centeres. Modules transfer complex data via ZigBee wireless protocol. This allows for a reduction of energy generation required for operational performance.
