New rail-road tractor with a combustion engine and an alternative electric drive

The paper presents the general concept of an innovative rail-road tractor solution. The innovation of the solution is characterized by equipping the combustion engine tractor with an additional electric drive for the wheels of the rail drive system. The options of using the tractor in operation along with rolling stock were presented. The results of preliminary conceptual work on the selection of electric propulsion and energy storage devices to power electric motors has been illustrated. Directions for further conceptual and design research were also determined. The aim of the paper is to popularize the results of the performed research work carried out at the Institute in the field of rail-road vehicle development.
