Abstract: The paper presents modernized diesel locomotives manufactured by plants based on documentation from the IPS “Tabor” Poznań. The technical parameters of the locomotives obtained after modernization are presented, along with general descriptions of new and modernized systems, assemblies, and equipment. Furthermore, proposals for the modernization of other types and series of diesel locomotives operated on the tracks of Polish Railway Lines are presented.
1. INTRODUCTION
The Rail Vehicle Institute “Tabor” in Poznań has been participating for several years in the process of modernizing the electric and diesel traction vehicle fleet.
Limiting ourselves only to diesel-powered traction vehicles, the modernization work carried out in the country, in which IPS “Tabor” Poznań participates, results on one hand from the lack of production of new diesel locomotives, and on the other hand from the fact that rolling stock users possess outdated and expensive-to-operate equipment that is “young in age” and could, after modernization, serve in operation for the next 15÷25 years [3].
Taking into account the economic situation of individual users and the fact that importing modern locomotives from abroad involves a large expense, most operators will look for savings by implementing modernized locomotives already in their possession.
It should also be noted that the modernization process of diesel locomotives also stems from the following premises [3]: keeping up with progressive technical development, maintaining and operating rolling stock that meets increasingly higher market requirements, the balance between the technical level of existing and new rolling stock, and the increasingly higher requirements of train drivers and service personnel in relation to outdated rolling stock.
