The application of rail buckling models is often limited by uncertain information with respect to track properties, and many conventional are poorly suited network-wide or even regional application. Here, a methodology using fuzzy sets presented that, when trained data can use inputs properties predict the minimum temperature increase for particular track. An investigation impact size training ...

In railways, using a track- and ride-quality monitoring system on in-service train has become desirable for coordination security. Identification of the or train-related rough rides via crew can be estimated to nearest kilometre. However, if is equipped with better location track quality evaluation provided. These systems commonly use information such as GNSS and/or an odometer provide informat...

In the United States, the freight railway industry is already running without much excess capacity. Hence, better planning and scheduling tools are needed to effectively manage the scarce resources, to cope with the rapidly increasing demand for railway transportation. The integration of freight train and passenger train scheduling and dispatching is an important railroad management task since ...

In this paper, we follow the track of previous papers by the same author, with various collaborators or alone, see [2, 7, 13, 14, 10, 9], which make use of the same basic model, the railway model, see [16, 5, 9]. In order to be within the space constraint for the paper, we just refer to the above mentioned paper both for what is the railway model and for what is hyperbolic geometrY. For the lat...

Railway tunnel clearance is directly related to the safe operation of trains and upgrading of freight capacity. As more and more railway are put into operation and the operation is continuously becoming faster, the railway tunnel clearance inspection should be more precise and efficient. In view of the problems existing in traditional tunnel clearance inspection methods, such as low density, sl...
