Abstract

The methods that are widely used today to determine the required locomotive fleet, the Corresponding maintenance and repair system consider the locomotive as a whole, without taking into account the technical condition of its individual units, which have a limited life cycle. Furthermore, the methods used today do not take into account the time spent on relocation from an operational locomotive depot to a service depot and back. The purpose of this study is to develop the methods for determining the number of locomotives based on the anticipated workloads for specific operational sections, the necessary accompanying maintenance and repair, the optimized repair cycle structure with due account of the available resources of the limiting units in the railroad operating domain which are capable of taking into account the technical condition of equipment (failures, repair costs, and time spent on relocation from one depot to another). A model for organization of repair of gas turbine locomotives assigned to operational locomotive depots while undergoing repair in service locomotive depots is proposed. Using this model, it is possible to develop a software product for distributing routine locomotive repairs among service providers, thus optimizing the workload of the latter.

Summary

Introduction

Development of the Far North regions is an important economic problem for the Russian Federation. Within the framework of the “Strategy for Developing Rail Transport in the Russian Federation up to 2030” approved by the Government of the Russian Federation, the Northern Latitudinal Railway, railroad lines in the sections Obskaya–Salekhard (54 km long), Salekhard—Nadym (355 km), Nadym—Pangody (111 km) will be built. Since the railroad lines of the Northern Latitudinal Railway will not be electrified, a promising rolling stock includes locomotives with a gas turbine engine (LGTE) running on liquefied natural gas (LNG), i.e. mainline gas turbine locomotives GT1h, which showed good performance results during experimental operation on the Sverdlovsk railway. To move away from this, starting 2005, RZD OJSC launched a complex of research and development works to create a locomotive with a gas turbine engine (LGTE) operating on liquefied natural gas (LNG). The gas turbine locomotive (GTL) is serviced by STM-Service LLC in Artyomovsky service locomotive depot (SLD); the GTL is operated by crews of Egorshino operational locomotive depot
