This paper presents a health condition monitoring system for insulated rail joints (IRJs)
based on axle box acceleration (ABA) measurements. The ABA signals from all the wheels …

The aim of this paper is to demonstrate the possibilities of estimating the track condition
using axle-boxes and car-bodies motions described by acceleration signals. In the paper …

Punctuality is regarded as an important measure of the performance of a railway system,
and is the one most commonly used and discussed measure both in the industry and among …

Resandet med tåg har ökat stadigt i Sverige de senaste 30 åren. Takten har varit cirka två-
tre procent per år, och vi nu har mer än dubbelt så många resenärer. Med ökat fokus på …

This paper presents a condition-based treatment methodology for a type of rail surface
defect called squat. The proposed methodology is based on a set of robust and predictive …

ABSTRACT A probabilistic Track Performance Index (TPI) is proposed for maintenance
prioritization in the railways. TPI evaluates the safety condition in a segment by estimating …

The evaluation theory of reliability, availability, maintainability and safety (RAMS) as a
mature theory of state evaluation in the railway engineering, can be well used to the …

This paper describes an easy way to monitor railway track abnormalities and update
information on the track's status to the cloud. Abnormalities present in railway tracks should …

Railway maintenance especially on infrastructure produces a vast amount of data. However,
having data is not synonymous with having information; rather, data must be processed to …

During a typical measurement campaign, lots of temporal and spatial data can be gathered
regarding the condition of the rail. This paper proposes two approaches that make use of …
