Embedded Railway Ballast Moisture Sensing
Railbed health is an important aspect of safe transportation by train. If not properly maintained, over time this can lead to track misalignment and compromised load-bearing capacity. If the tracks are compromised in any way, catastrophic derailment is more likely. Additionally, the massive financial burden that misaligned tracks carry with them is...
