One of the major drawbacks in rail track investments is the high level of uncertainty in maintenance, renewal and unavailability costs for the Infrastructure Managers (IM) during the life-cycle of the infrastructure. Above all, rail track geometry degradation is responsible for the greatest part of railway infrastructure maintenance costs. Some approaches have been tried to control the uncertai...

The weak expansive soil subgrade of the railway in operation is prone to settlement a high-temperature climate, which results rapid deterioration geometric dimensions track, and affecting safety train operation. This paper uses Track Geometry Measurements (TGM) analyze characteristics track geometry parameters soil. Also establishes Settlement Prediction Model (SPM) identify time predict value ...

The article discusses an important issue of railway line construction and maintenance, which fundamentally is the verification geometric parameters track. For this purpose, mobile measurements have been performed using a measuring platform with two properly arranged GNSS receivers, made it possible to determine base vector platform. functionality system was extended by IMU. In article, effect c...

This study aimed to develop a multi-objective approach for reducing the positional errors in geometry measurements of track as linear asset. Accordingly, we evaluated and compared two alignment methods – recursive segment-wise peak (RSPA) modified correlation optimised warping (MCOW). Furthermore, novel rule-based was introduced avoid data loss while aligning datasets assets. A case conducted i...
