The Chicago Transit Authority (CTA)’s train system, commonly known as the “L” or “El”, includes several train lines. The “L” consists of eight lines that operate on elevated tracks, subways, and at-grade sections throughout Chicago and some surrounding suburbs.

Here are the eight CTA train lines
Blue Line, Brown Line, Green Line, Orange Line, Pink Line, Purple Line, Red Line, and Yellow Line.
The “L” system provides rapid transit service with over 140 stations across the city and nearby suburbs. The nickname “L” is derived from “elevated” due to the system’s early elevated track sections.
