• Rail Vehicles, Semester 3, position 1

1. Introduction student to the basic concepts important to understanding the the designing of diesel-electric and electric locomotives. 2. Knowledge acquiring necessary for understanding the designing of diesel-electric and electric locomotives. 3. Competence for use the knowledge acquired in solving practical problems in designing, use and maintenance of diesel-electric and electric locomotives.

After successfully finishing of course students would be able to: - define basic characteristics of diesel-electric and electric locomotives; - describe tasks and way of functioning of the main assemblies of diesel-electric and electric locomotives; - compare ways of functioning and control of electric drive motors for DC and AC power; - calculate the key tractive parameters using special software package; - implementation of regulations and standards in field of diesel-electric and electric locomotives.
