​Atlanta to Chattanooga
High Speed Ground Transportation (HSGT)

One possibility to keeping highway traffic congestion down and Georgia on the move is by providing new high speed ground transportation (HSGT) trains between Atlanta and Chattanooga. A study of this 110-mile corridor to determine a preferred corridor route and potential train technologies is underway.

The outcome of the current study – a Tier 1 Environmental Impact Statement (EIS) – will provide the Georgia DOT, the Tennessee DOT, the Federal Railroad Administration (FRA) and the Federal Highway Administration (FHWA) with sufficient information to select a general corridor and general station locations. In addition, the document will identify train vehicle technologies that should be considered further to provide high speed service.


 What is High Speed Ground Transportation?


HSGT is an option for the Atlanta to Chattanooga corridor for several reasons. Mostly, because it can provide quick, reliable, environmentally freindly, and comfortable city- to city- travel at speeds of 180 mph or greater – getting you where you want to go faster. The Atlanta to Chattanooga corridor has been a focus area in recent years for development of a new train system to improve transportation between the two cities.

The Atlanta-Chattanooga HSGT project is considering the following two HSGT technologies, which are the only two available that meet the project’s minimum speed requirement:

Magnetic Levitation (MAGLEV)

  • Potential speeds over 300 mph
  • Station spacing 30+ miles
  • Grade separated right-of-way
  • Electric power to magnets from track
  • Magnetic force lifts and propels on guideway

Steel Wheeled

Steel Wheeled
  • Potential speeds up to 220 mph
  • Station spacing 30+ miles
  • Grade separated right-of-way
  • Electric power from overhead wires to vehicle
  • Steel wheel on steel rail


Transportation demand is outpacing existing and planned roadway capacity between Atlanta and Chattanooga. Currently, there are three major highways serving the corridor: I-75, US 41, and US 27. These highways are projected to operate at or above capacity by the year 2025. There is a need for additional capacity, but increasing vehicular capacity alone may not be an adequate strategy.


 Project Info



This Tier I EIS will investigate and assess transportation, environmental and planning issues for potential HSGT service developed for the study.

The potential corridor alternatives will include, a variety of routes, station locations, operating plans and potential for phased implementation. The study will also estimate ridership, capital and operating costs, revenue projections and economic impacts.


The purpose of the Atlanta – Chattanooga HSGT Project is to enhance intercity passenger mobility and economic growth between the metropolitan areas and airports of Atlanta, Georgia and Chattanooga, Tennessee by providing new, high-speed ground transportation passenger service. The Project is also intended to provide faster and more reliable intercity travel in the corridor by providing an alternative to highway, intercity bus, and air travel in a manner that is safe, reliable, and cost-effective, while avoiding, minimizing, and mitigating impacts on the human and natural environment.

HSGT Benefits

  • Enhance regional transportation mobility and accessibility
  • Spur economic growth and regional vitality
  • Provide safe, efficient, reliable transportation
  • Enhance airport access and intermodal connections
  • Improve air quality nonattainment areas and minimize environmental impacts

 Scoping Process


During the scoping process, 15 unique corridors extending from Hartsfield-Jackson Atlanta International Airport to downtown Chattanooga were identified.  A map of each can be seen by clicking on each corridor name from the drop down list below.



Why was the route to Chattanooga selected?
What is the cost of the project?
How many people are expected to use HSGT in this corridor if it is constructed?
When is the system expected to be open to the public?
How frequently will the trains run?
How safe are these high speed rail systems?
Will the Tier 1 Environmental Impact Statement (EIS) identify a preferred technology in addition to a preferred corridor?
What are the differences in energy consumption between Steel-Wheeled and Maglev?
Does Maglev passenger service operate today? If so, where?
Does high speed Steel-Wheeled passenger service operate today? If so, where?
What are the initial thoughts on passenger fares?
What are the considerations for park-and-ride lots?
Have station stops been identified?
Why are there no stops South of Atlanta?
I am concerned about jobs for Georgians. How many jobs will this project bring to the communities, especially for minorities?
During the Scoping Meetings, many different corridors were identified. Are all the alignments going to be examined in more detail in the Tier 1 EIS? If not, how will this selection be done?
