Yes, you can take MARTA from ATL Airport to College Park Station. Pretty sure it's just one stop away.
Indeed. Leaving the airport aboard a MARTA Train, the first stop is College Park Transit Station. You can board the GOLD or RED line at the airport. There's no difference in this case, they both stop at College Park Transit Station. NOTE: If you are at the International Terminal, you will need to board the free shuttle to the Domestic Terminal(curbside, lower level). You will be dropped off outside of the MARTA Airport Station.
