Round 1

Reviewer 1 Report

1. The thesis title needs to be corrected.

critical speed of curve derailment --> Critical Derailment Speed running on Curved track

2. Uniformity of terminology throughout the paper.

progressive trial calculation method ; progressive trial method

root locus method ; root trajectory method

limit cycle method ; limit loop method ; limit ring method

3. Correct the terms in the table 2.

line --> alignment

Linear -->alignment

Ultra High --> Cant

4. What is the physical significance of the results in Figure 5? And in root trajectory and  limit loop method, it is necessary to explain exactly whether the curve condition is not taken into account.

5. Please describe the author's argument while quantitatively comparing the disadvantages of limit loop method described at the top of page 6 with the method proposed in this paper.

6. There are no research results in the paper to support the first conclusion.

7. It is difficult to judge that conclusions 2 and 3 explain the complex process of derailment.

Round 2

Reviewer 1 Report

Thank you for carefully reviewing and reflecting the reviewers' opinions.

Please consider the following:

1. The title needs to be revised to represent the results of this paper. The title of the currently revised version is very lacking in meaning.

2. There are English sentences that are difficult to understand. Please seek professional help. I recommend editing with the help of a technical writer.
