Chicago Metra commuter train 1245 makes its stop at the carrier's Harlem Avenue Station as the sun sets. METX F40PHM-2 195 is pulling seven gallery cars from downtown Chicago (visible by the Willis Tower in the distance) to the western suburb of Downers Grove (or, as it is listed on a Metra website's page: Downers Groove!). Chicago's Regional Transportation Authority's Metra (short for or Metropolitan Rail) is the second-largest and second-busiest commuter rail operation in the United States, second only to New York City's Metropolitan Transit Authority.
