This article examines the use of thermal imaging diagnostics for the maintenance of electrical centralization devices in railway automation. It analyzes traditional diagnostic methods, their limitations, and the risks associated with the late detection of faults (overheating). The effectiveness of thermal imaging control in detecting overheating of relay contact groups, conductor joints, transformers, and other crucial elements of electrical centralization has been proven. Mathematical models for analyzing thermal deviations are proposed, which allow predicting failures before the equipment malfunctions. The economic effectiveness of implementing thermal imagers in railway infrastructure is substantiated. The use of this technology enhances safety, reduces maintenance costs, minimizes emergency situations, shortens repair time, and improves overall equipment condition control.
