Question: does the m train go to broadway junction

Answer: No, Broadway Junction is a New York City Subway station complex shared by the elevated BMT Canarsie Line and BMT Jamaica Line, and the underground IND Fulton Street Line. It was also served by trains of the Fulton Street Elevated until that line closed in 1956. It is located roughly at the intersection of Broadway, Fulton Street and Van Sinderen Avenue at the border of Bedford-Stuyvesant and East New York, Brooklyn. The complex is served by the A, J, and L trains at all times; the C train at all times except late nights; and the Z train during rush hours in the peak direction only.
