Original Note:
This is called a derailer. There are many uses for these which include stopping rolling stock (train cars) that get loose, protecting personnel nearby on the track, or preventing access to hazards or unauthorized areas. https://www.alberta.ca/derail-device.aspx https://industryrailway.com/safety-security/derails https://en.wikipedia.org/wiki/Derail
