On the project

Projekt je zaměřen na výzkum a vývoj v oblasti technologií pro zvyšování efektivity kolejové dopravy, konkrétně na posílení implementace tzv. Friction Managementu. Tento moderní a progresivní přístup může být zcela zásadním pro udržitelnost konkurenceschopnosti kolejové dopravy. Implementací tohoto přístupu je možné zvýšit bezpečnost a komfort kolejové dopravy, redukovat degradaci infrastruktury a kolejových vozidel a v neposlední řadě také snižovat negativní environmentální projevy, kde nejaktuálnější problém představuje zejména zvýšená hlučnost v urbanistických celcích.

Description in English
Top-of-rail products represent a modern approach to control adhesion, wear reduction and noise reduction in rail transport. At present, different types of TOR products are available on the market, differing in chemical composition or application methods. Moreover, the behavior of these substances is significantly influenced by operating parameters and climatic conditions. This means that the behavior of the TOR product and hence the expected benefits may vary depending on the type of track system or geographic conditions. The aim of the project is to clarify the impact of TOR products on the degree of adhesion, wear, contact fatigue and noise emission for a wide range of operating and environmental conditions. Furthermore, the ability to redistribute these substances, which is crucial in terms of the length of the rail treatment, will be studied. Last but not least, it will be examined whether the application of these substances can interfere with the function of the railway safety devices.
