Abstract

fetched live from OpenAlex

There is little content on track–structure interaction in current manuals and standards. This paper suggests a method to compute permissible additional tensile and compressive stress in a continuously welded rail of a ballasted transit track due to track–bridge interaction. The method may be followed for other types of track, e.g., direct fixation fastener track. Thus, this paper provides a practical approach for calculation of additional rail stress limits for engineers practicing in the field of railway/bridge designs. The permissible additional tensile and compressive stress is suggested for a ballasted transit track on a bridge. Preventive measures are also discussed in the event of exceedance of permissible stress.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
