Question: does the purple line go to union station

Answer: Yes, The Metro Purple Line is a 6.4-mile (10.3 km) line that begins at Union Station. At Union Station, passengers can connect to the Metro Silver Line bus rapid transit line, and the Metro Gold Line. The Purple Line travels southwest through Downtown Los Angeles, passing the Civic Center, Pershing Square (near the Historic Core) and the Financial District. Passengers can connect to the Metro Silver Line (both directions) at Civic Center Station. At Pershing Square Station, passengers can board the northbound Metro Silver Line bus at Olive Street/5th Street. At 7th St/Metro Center Station, travelers can connect to the Metro Blue Line, Metro Expo Line and the Metro Silver Line. From here, the train travels between 7th Street and Wilshire Boulevard (and briefly Ingraham Street) west through Pico-Union and Westlake, arriving at Wilshire/Vermont in the city's Mid-Wilshire/Koreatown district. Up to this point, track is shared with the Metro Red Line: at Wilshire/Vermont, the two lines diverge. The Purple Line continues west for one additional mile, and terminates at Wilshire/Western.
