Audit review
The paper’s finite-element assembly, wheel–rail kinematics under permanent contact, vehicle–rail coupling blocks, global system assembly, and Newmark-β discretization match standard formulations and align with the candidate solution. The candidate’s derivation cleanly reproduces the same element matrices, interaction terms, connectivity, and the effective Newmark system. The paper, however, contains several typographical/notational errors (e.g., a misordered equation of motion and a mischaracterization of Newmark as “explicit” and “unconditionally stable”), but its core derivations and final block forms agree with the model’s solution.
Referee report (LaTeX)
\textbf{Recommendation:} minor revisions
\textbf{Journal Tier:} note/short/other
\textbf{Justification:}
The manuscript offers a clear assembly pathway for a coupled vehicle–rail–bridge FE model and is consistent with standard results. Its main contribution is pedagogical and implementation-oriented. However, several typographical errors (a misordered equation of motion) and an incorrect characterization of the Newmark method could mislead readers. Addressing these minor issues would substantially improve clarity and correctness.
