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...

Ensuring safe train operation, minimizing service interruptions, and optimizing maintenance procedures are primary railway industry focus areas. To support these goals, a multi-disciplinary team of researchers at the University Illinois Urbana-Champaign proposed wireless, continuous, accurate methodology to monitor track conditions. This project, referred as “Smart Track”, included development ...
