What is it about?
For open-pit locomotives, application of the existing equations for calculation of the temperature for main-line railway transport is inappropriate, since it doesn`t take into account the specific conditions of the open-pit mining, such as increased track gradients.

Why is it important?
Therefore we proposed to calculate the temperature in the contact zone at the wheel-rail interface according to the derived equation, which takes into account the track gradient of the open pit`s rail truck. The calculation results, which were made according developed computational technique, show satisfactory repeatability with the experimental results.
Perspectives
Writing this article was a great pleasure as it has co-authors with whom I have had long standing collaborations. The results of calculations done as we developed the methodology, show a satisfactory reproducibility of the experimental results. These calculations we hope will help other researchers.
