Compared with the pin-through rail anchor, the cassette rail anchor has a reasonable design, simple structure, easy installation and maintenance, and long service life. It is at least twice that of the pin anchor; it has good anti-climbing performance and advanced technology. The anti-climbing is reliable, does not loosen, does not fall off, the effect is lasting, the anti-climbing resistance is large, and the anti-climbing effect is good; the use cost is low. The cost of the new rail anchor is basically the same as that of the pin-through rail anchor, but the number of configurations for each group should be reduced by more than 50%. Therefore, the maintenance period is long, which greatly reduces the maintenance cost of the railway.
