Approximate Bayesian computation for railway track geometry parameter estimation

Proceedings of the Institution of mechanical engineers. Part F, journal of rail and rapid transit, 2020
The quality of track geometry is directly linked to vehicle safety, reliability and ride quality. The performance of track is therefore considerably hindered when track geometry indicators deviate from the specified and approved limits due to loads and ...

Vehicle reactions versus track geometry

ASME/IEEE Joint Conference on Railroads, 1990
For assessment purposes the total range of relevant wavelengths for differential settlements is split up into a number of wavebands in accordance with vehicle response characteristics to deformations in the track geometry and the potential of maintenance machines to correct the track geometry.

Autonomous track geometry diagnostics system

Journal of Materials Processing Technology, 2004
Abstract The paper presents the background of the diagnostic analysis for railways and trams (DART), automatic diagnostic analysis tool for the track geometry measurement data—as separate track data files or track data read from the database. The diagnostic module indicates the “weak locations” in the track, which can be further analysed in detail by

Track Structure, Chromosome Geometry and Chromosome Aberrations

1994
The joint role of radiation track structure and chromosome geometry in determining yields of chromosome aberrations is discussed. Ideally, the geometric models of chromosomes used for analyzing aberration yields should have the same degree of realism as track structure models.
