Publisher Correction: Bayesian Multivariate Track Geometry Degradation Modeling and Its Use in Condition-Based Inspection
This publisher correction addresses a typesetting error in Figure 18 of the original article 'Bayesian multivariate track geometry degradation modeling and its use in condition-based inspection' published in Railway Engineering Science. The correction notice, published online on 3 December 2025, provides both the incorrect and correct versions of Figure 18, which is central to the visualization of track geometry degradation predictions. The original article, identified by DOI 10.1007/s40534-025-00394-4, presented a Bayesian framework for modeling multivariate degradation of track geometry parameters—including gauge, crosslevel, alignment, and profile—to support condition-based inspection scheduling. The erroneous figure compromised the interpretation of posterior predictive distributions and inspection thresholds. The corrected figure restores the accurate representation of degradation trajectories and associated uncertainty intervals, ensuring that maintenance decisions derived from the model remain valid. This correction is critical for railway asset managers who rely on the model's outputs to optimize inspection intervals and reduce lifecycle costs. The authors and publisher affirm that the scientific conclusions of the original work remain unchanged.
