The article presents the investigation results of evaluation of the efficiency of 3VL80s three-sectional main freight electric locomotives (trains) used on the Kattakurgan – Navoi district of Uzbek railways with stop-and-go freight traffic at passing tracks, intermediate stations and interstations. 

The author gives the freight trains traveltime parameters and basic energy indicators of 3VL80S transportation work as numerical values and graphs as well as the regression equations to find the indicator values taking account of  mass variation of freight trains.

The research results are recommended to the specialists of Uzbek railway line-enterprises for developing the complex activities related to the rise of traction and energy efficiency of 3VL80s three-sectional main freight electric locomotives (trains) in organizing freight traffic on the hilly-mountainous Kattakurgan – Navoi district of «Uzbekiston Railways» JSC.

Keywords: efficiency, result, freight train, movement, electric locomotive, district, method, exploitation, speed, calculation, rolling – stock, analysis, hilly-mountainous, point, dependence, substantiation, stage, railway.
