ON POSSIBLE WAYS OF MODERNIZATION OF DOMESTIC DIESEL LOCOMOTIVES

Abstract

The objective of the author is to investigate technical requirements and possible ways of modernization of current freight diesel locomotive fleet. The author uses analysis, comparative method and evaluation method. The author suggests approaches to modernization of diesel locomotives 2TE25K andTEP80 to be further used for freight traffic. The article describes main technical specifications for multipurpose locomotive that can be used both for passenger and commuter train haulage at not electrified railways. The author argues that diesel locomotive TEM21 is suitable for that purpose once it is modernized. Meanwhile, locomotive fleet needs to be replenished with new machines that could effectively replace outdated models.

The article offers three different modernization programs for locomotives of domestic production, designed for different purposes, – freight, passenger, shunting locomotives. Demonstrated options are based on optimization calculations, carried out with the participation of students of MIIT. Changes in locomotives’ parameters and related operational benefits are estimated.
