Abstract
This study investigates the thermal performance of passenger car body enclosures using a controlled test chamber. Due to the relatively high heat transfer coefficient of existing designs, the need for improved thermal insulation has been identified. Modern insulation materials with low thermal conductivity were analyzed, and four prototype samples were tested. The best results were obtained from samples using corundum and polyurethane foam. These materials also provide effective corrosion protection. To ensure measurement accuracy, the test chamber was calibrated. The study presents a validated methodology for selecting thermal insulation materials for railway rolling stock.
