Cta Performance

I tried to make a little money while sharpening my skills performance. I play guitar and sing, write my own songs. I've seen performers working at the CTA subway stations and various el in the past and I wonder if there are special rules or if a permit is required to make the CTA stations. Also, do not allow Metra to perform?

Yup. You did not use, but it must be so many guys out there that they began to have allowed. You must go to city hall to get that. Check the official City of Chicago site. They even have specific times and areas where men can do (for example, you could have the slot 2-6 hours and someone else may have that space from 6-9)

Do not know Metra.
