Recently, due to the increasing volume of traffic and the lack of specialized transport, new engineering solutions are being sought, one of which is the modernization of the existing fleet of thermos cars to extend their service life. The aim of this study was the hygienic assessment of the modernized thermos car model 16-6894 for its compliance with the current Rules for the carriage of perishable goods by rail. Perishable goods include food products requiring compliance with certain temperature and humidity conditions during storage and transportation. To confirm the compliance of the temperature in the thermos car with the requirements of sanitary and hygienic rules and regulations, a corresponding study was conducted. According to a special program, tests were carried out to determine the time of heating the air in a thermos car using a simulator of deep-frozen products (frozen water) in order to further establish the deadlines for transportation in the summer and transitional periods of the year. The result of the research was the development of computer software that allows predicting the timing of transportation of any frozen food for certain specified conditions.
