Setting of Fahrenheit 451

Currently I started to read the book Fahrenheit 451 by Ray Bradbury. I have only read the first third of the book. This story takes place in a unnamed city but sounds like it might be something similar to modern day New York. This story takes place in the future very far, it takes place in the twenty fourth century. "He walked out of the fire station and along the midnight street toward the subway where the silent air propelled train slid soundlessly down its lubricated flue in the earth" (Pg 3). This tells you that it takes place in a city because only big cities have subways.
