Abstract
The article presents the results of a statistical analysis of the microclimate parameters (temperature, the environmental heat load index – EHL-index) in the cabins of electric locomotive drivers of the EP1M, 2ES5K and VL-80 series. The study is based on data of a special assessment of electric locomotive crews’ working conditions carried out at different times of the year. The methods of descriptive statistics and data visualization revealed that the empirical distributions of the studied parameters differ significantly from the normal one and represent a mixture of several components, each of which corresponds to a certain class of working conditions and is close to the normal distribution. It has been established that the effect of a heating microclimate poses a greater risk to locomotive crew members compared to the cooling one. The results of the work serve as the basis for the development and validation of mathematical models of heat and mass transfer, as well as for the design of microclimate normalization systems and devices in drivers' cabins to ensure workplace safety and safe railway operation of rolling stock.
The temperature parameters of the external environ-ment influence such performance indicators of a rotary snow blower as energy efficiency and productivity, which also largely determine the quality of cleaning. The article describes a hardware and software system designed to collect and process data on the operation of...

In hot climates, the ambient air temperature can reach 45 °C and more, which leads to heating of the windings of power transformers above the permissible values and, accordingly, to a reduction in their relative service life. The purpose of the study is to determine the values of relative service life and the factors a...
