Track geometry quality assessments for turnouts
Transportation Engineering, 2023 Turnouts are necessary, frequent and cost intensive. Despite the railway sector's focus on automation, the condition assessment of turnouts is still mostly done manually by responsible staff inspecting the turnout.

The interaction between railway vehicle dynamics and track lateral alignment [PDF]
, 2016 Track geometry deteriorates with traffic flow, thus it needs to be regularly restored using tamping or other method. As the deterioration is mainly in the vertical direction this aspect has been widely studied and models for its analysis developed ...

Performance-based track geometry and the track geometry interaction map
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2008 The track geometry interaction map (TGIM) is proposed as an effective way to evaluate the impact of multiple track geometry parameters on rail safety. Multi-body dynamics software has been used to simulate vehicle performance over tracks containing a large number of randomly generated lateral and vertical track geometry combinations.
