Turnouts consist of complicated and movable structures, therefore the risk of failures is higher than a normal track. Though there are various causes of switch failures, the influence of track irregularities and maintenance conditions for switch failures is still unknown. To avoid the switch failures, it is required to study the influence between switch throwing force and track irregularities and maintenance conditions. In this paper, we make formulas to calculate the switch throwing force depending on the types of track irregularities and maintenance conditions and calculate them in a case as an example.
