The Local Take Talks Transportation for DeKalb County | WCLK Mr. Parker's editorial spoke about using light rail as opposed to hard rail lines. He mentions that most metropolis are relying on light rail. He provides examples of light rail from the Plane train at Hartsfield-Jackson International Airport to the downtown street car.

He speaks to having a direct line from the airport to DeKalb. Additionally light rail lines from South DeKalb to North DeKalb. His idea to turn MARTA's Kensington Station into a modal line hub.

Mr. Parker seems to not have a clue about the subject he is trying to talk about.

Actually I will back up his claim that alot of cities are relying more so on light rail than heavy rail these days. Less than a handful of metro's are performing any expansion on heavy rail, most rail projects these days in other cities are going toward light rail and commuter rail as both are probably alot cheaper than heavy rail (commuter rail relies on existing track and light rail does not have to have grade separation in most instances.) where as heavy rail these days must include grade separation (reinforced bridges, or tunnels are both very expensive).

Salt Lake City, Denver, Minneapolis, DFW, Houston, Charlotte, Los Angeles, San Francisco, countless others have a light rail in place.

...now the light rail line between Dekalb and the Airport... I don't know about... Between South Dekalb and North Dekalb (or atleast Downtown Decatur to Emory to Doraville and then westward to Perimeter) might not be a bad idea though... wouldn't be cheap or easy to implement though either.

First off we need someone who is qualified to talk about this and he isn't.

Second just because another cities are doing something doesn't mean we should do it. DC, NYC,etc are expanding heavy rail so why not follow their lead?

Third. If you are going to do it do it right and don't half a__ it.

The underground Plane Train and ATL SkyTrain are not light rail, but rather Automatic People Mover. This guy has no idea about transit.

SF is expanding it's HRT system, on the East Bay to San Jose. LA is expanding the Purple Line along Wilshire Blvd.
The other cities listed started their rail transit systems from scratch so using the less expensive light rail made sense. For Atlanta, extending HRT along existing lines (where commuter rail does not run along the same corridor; eg: 400 North and 20 East.) Forcing a transfer along the same the corridor will reduce ridership significantly.

What is wrong with light rail for South DeKalb? It beats another 45 years of nothing.

Most cities don't already have a heavy rail backbone. If you are starting from scratch it makes more sense as you don't have to have grade separation everywhere (for example in downtowns). If you already have the heavy rail backbone, it doesn't necessarily make more sense.

Neither are the denizens of CD but it doesn't stop us from yammering on about it day and night. Let him talk about it if he wants to.
Personally, I would prefer HRT for longer distances and denser, more high-trafficked areas. But in the absence of that I'll take anything that precludes an internal combustion engine.
Let HRT and Commuter Trains be the Spinal Cord, LRT be the Neurons and Streetcars be the Neuroglia. And then let's build a Brain in the form of a Multimodal Transit Station.

Even though this guy doesn't know what it's called, I will say that an Automated People Mover system around the whole metro area, elevated and in tunnels, would have been a great solution for Atlanta. And still would be. Particularly in the city and in the job center/ edge city areas.

There's no driver/conductor/pilot whatever they're called, so there's some savings there. And it also allows for very high on-time reliability, especially with the dedicated ROW of being elevated. Vancouver SkyTrain has ~50 miles of track, 53 stations.

APM also has a little bit more turn flexibility than HRT, as it uses shorter trains/smaller cars. And it uses station spacing more like LRT.

The downside is it only goes up to 50mph. But still, that's better than being stuck in traffic.
