Modular track panels for improved safety in the mining transportation industry
Locomotives and "mine cars" often derail (often two or three times daily) in coalmines causing fatal injuries, fires initiated from sparks during derailment, and costly downtimes. Modular track panels (resembling the ladder track systems used in Japan) were designed and tested for bending behavior …
