Using a combination of smart sensors, industry-wide data sharing and advanced analytics software, railroads monitor the health of the network and equipment in real-time. For example, thousands of smart sensors, known as wayside detectors, positioned along rail track throughout the country, monitor the integrity of railcars as they move at up to 60 MPH. Using a host of technologies, such as infrared and X-ray, the sensors assess the health of bearings, axles, wheels, springs and other equipment components in real-time. This information allows railroads to react quickly, preventing bigger repairs and even accidents.
Preventive maintenance also allows railroads to schedule repairs and fixes at optimal times and places, so trains stay as close to schedule as possible. And with fewer breakdowns, more trains are out on the tracks delivering goods and raw materials, instead of in the rail yard waiting for repair.
