Abstract

The results of the analysis of the distribution of the operating time of EP2K electric locomotives of the assigned fleet of the Barabinsk operational locomotive depot in the sections of the Ural-Siberian region showed that since 2015, EP2K electric locomotives have been operated in addition to the West Siberian and Sverdlovsk railways, also on the South Ural and Kuibyshev railways.

As the analysis of the plan and profile of the track at the EP2K electric locomotive operation range, curves of small radii (less than 400 m) prevail on the South Ural and Kuibyshev railways (up to 50% of the length of traction arms), which led to increased wear of the tires of the wheelsets of EP2K electric locomotives of the assigned fleet of the Barabinsk operational locomotive depot.

The intensity of wear of the flanges of the middle wheelsets of bogies is 9.5 times higher than the intensity of wear of the flanges of the outer wheelsets. Consequently, the middle wheelsets are as often turned as the outer wheelsets. If we take the minimum maximum thickness of the flange of the trough of middle wheelsets of bogies, equal to 21 mm, then in this case, other things being equal, the service life of the drum will increase by 147015 km.
