Learning outcomes
|
This subject is focused on the basic principles of modelling of train run, including the analysis of factors influencing the train dynamics. Students learn to solve the basic tasks of traction mechanics - calculations of running time, train weight and energy consumption.
After completing the course, the student understands the physical phenomena that affect the movement of the train and is able to independently model the train to investigate travel times and traction energy consumption.
