railway infrastructure

The paper presents research results on the application of infrared thermography for diagnostics of machines and devices in railway infrastructure. The theoretical foundations based on Fourier’s heat conduction equation are outlined and the principles of designing an automated diagnostic system using thermal cameras, a data processing server, and machine learning algorithms are described. Examples of thermograms and graphs illustrate the detection of defects in cable connections, rail joints and turnout drives.

The railway transport system in Ukraine stands as a pivotal sector within the nation's transportation infrastructure, accounting for a substantial portion of freight and passenger movement compared to domestic alternative modes of transportation. With direct border connections and collaboration with railways in Moldova, Poland, Romania, Slovakia, and Hungary, Ukrzaliznytsia JSC facilitate operations through forty international railway crossings.
