Abstract
This paper presents the results of an analysis of the operating modes of the locomotive friction activation system (UATL) installed on 3ES5K electric locomotives, based on data obtained from supervised operation on the Eastern railway corridor.
The study is based on decoded data from microprocessor-based locomotive control systems (MSUD) for 2025 and includes 2 629 train trips performed by 11 electric locomotives.
A comparative analysis was carried out for locomotive operating modes with the UATL system switched on and off under similar operating conditions using specific performance indicators. The results show that, despite the technical operability of the system, its actual use is uneven and largely depends on organizational and human factors. It was shown that the UATL system operates primarily in automatic modes and has high potential for reducing the load on the sand delivery system and the locomotive crew.
It was concluded that it is necessary to implement regulated approaches to UATL use to improve the efficiency of locomotive fleet operation.
