Until now, the automatic under load condition monitoring of tramway's track has not been applied in Hungary. Due to the lack of track recording car, only the visual inspection on track was used for identifying track defects. This paper presents automatic methods for detecting track irregularities on tramway operation using acceleration measurements...

Nowadays, condition monitoring has wide applications in the railway industry, and various monitoring approaches have been proposed for the inspection of track conditions. The track experts in tramway operation consider the unloaded track geometry measurement and visual inspection of track sufficient for planning maintenance work thanks to the fact...

This paper presents an automatic method for detecting vertical track irregularities on tramway operation using acceleration measurements on trams. For monitoring of tramway tracks, an unconventional measurement setup is developed, which records the data of 3-axes wireless accelerometers mounted on wheel discs. Accelerations are processed to obtain...

The increasing demands for guided transportation modes in urban areas generate the need of high-frequency services. Due to the frequent services, the track deterioration process will be accelerated. Therefore, the exact knowledge of track quality is highly important for every railway company to provide high quality service level.For monitoring of t...

The exact knowledge of track technical state is highly important for every railway company. In the case of Hungarian tramway operation there is neither under-load track geometry measurement nor decision support system for track specialists available, which would help the planning of the maintenance work. In Hungary recently used condition assessmen...

In the case of guided transportation systems the acting cyclical loads in track-vehicle interaction can change in wide range depending on both the type and technical state of the vehicle and the track. Due to the urban traffic-control constraints significant additional loads can be formed from the combined effects of weather conditions and driving...

The first integrated railway system in Hungary (“tram-train”) is currently in planning phase, between Szeged and Hódmezővásárhely. The implementation of this system requires a special vehicle which has the ability to operate both on tramway infrastructures and also on conventional railways, and the necessary construction and reconstruction of track...

The goal of this article is to determine the e ect of various material parameters to the fatigue life of the pavement struc- tures. Nowadays many types of mixtures can be built in the pave- ments, with di erent sti ness moduli. However, the Hungarian asphalt pavement design method can not handle that. The main cause of failure of the asphalt layers...

Thanks to financial support by the European Union, a number of tram and LRT development projects are initiated in Eastern-Europe. Some of them are well based; others seem to be "white elephant" projects. This paper summarizes experience in "new EU accession" countries together with the desired "SKOPJE LRT" scheme. Cities like Bratislava, Prague, Cr...
