Taiwan Railways: axle and equipment-box monitoring across the EMU fleet
Axle PT100 and electrical-equipment thermal monitoring on EMU trains.
- 8 / trainAxle PT100 sensors
- Fleet-wideEMU deployment
- Real-timeOps control feed
The problem
A Taiwan Railways EMU train carries hundreds of passengers at speed. On board are inverters, HVAC compressors, motor controllers and a dozen other electrical subsystems — any of which can overheat. The most critical is the axle: if a bearing fails at speed, the consequences can include derailment. There is no acceptable margin for missing it.
What was installed
Each train carries eight Thermalpas axle PT100 patches plus sensors on the major equipment boxes. Data uplinks over a 4G router and PoE gateway to TRA's Operations Control Center, alongside the existing video-monitoring platform, so dispatchers see each train's thermal status in real time.
The outcome
TRA's EMU fleet is almost universally equipped with the system. The maintenance team schedules bearing inspections by data rather than mileage, and axle data feeds TRA's predictive-maintenance scheduling and SCADA.
