The paper investigates the requirements to check rails of railroad switches (turnouts). Railroad switches of the most commonly used structures with rigid frogs always involve check rails. Check rails not attached to running rails allow performing the adjustment of flangeways under operation, which thereby significantly increases the durability of structures involving check rails. The safety criterion is the first and key requirement, since check rails as part of turnouts ensure safe passage of a wheelset of a rolling stock through the section with a crossing frog. The second most important criterion is a dynamic-kinematic one. The third criterion pertains to the provision of robustness of check rails. All the aforementioned criteria represent the essential and adequate requirements that must serve as the basis for working out permissible rate of wear for check rails and determining the size of flangeways for them. For the purposes of examining the stress–strain state of check rails, the reasonability of a the experimental-calculation method was estimated, protector checkrails were considered and efficiency and drawbacks of their implementation were analyzed.
