The interstate commerce commission was created in 1887, but it was mostly ineffective until the 1900s. what was the main reason for this?

Interstate Commerce Commission 
* created in 1887.
* its purpose was to regulate railroad by ensuring fair rates and ending rates discrimination

Its initial implementation was not successful because this law was not granted adequate enforcement powers. Its early years were filled with court litigation by parties who challenge its purpose and powers. 

Ithink that it would mean that they "go off," as in get extremely mad at, a person and tell them off, or tell them what is wrong in an extremely abrupt and angry way.
