Thanks for the link to the story. The proposed site presents an interesting trade-off. While a station closer to the city core would be preferred, space for storage tracks, lots of parking, and a direct connection to MARTA, even if it is at the end of a line well outside the city, is more important for a viable station. A direct connection to MARTA and access from the beltway around the city would provide a range of transportation options to the station.
If the Atlanta metro region and Georgia ever get their act together and expand MARTA and add commuter rail lines for a transit system that a city of Atlanta's size really should have, a train station at Doraville could become the suburban station for Amtrak and commuter trains, similar to New Carrollton or Rt. 128. It is odd, but it is also a sign of the state of passenger rail in parts of the US, that while Atlanta has one intercity train a day, that not even that has a direct connection to MARTA. DC, for comparison, has 4 Amtrak stations in the metro region, all of which are co-located with DC Metro stations. Big difference in transit connectivity that is easy to take for granted.
At least, they are looking at another site, but this could easily run into the same lack of funding problem that reportedly killed the plans for the 17th and Northside site.
