We use Q/P estimation equations to evaluate quantitative influence of various factors for flange-climb derailment. In these equations, many factors which influences the cause of derailments are considered to estimate accurate wheel loads, lateral forces and so on. Nevertheless it is too complex to use for usual track maintenance works, we extract influential factors for derailment with parametric studies. The results show that, twists and alignments influence causes of derailments more than another category of track irregularities, and that imbalance between right and left-side wheel loads and primary suspension stiffness influence more another category of rolling stock. Then we propose the simple linear equation that will be useful to track maintenance works.
