​Atlanta to Chattanooga

What is High Speed Ground Transportation (HSGT)?​

HSGT is an option for the Atlanta to Chattanooga corridor for several reasons. Mostly, because it can provide quick, reliable, environmentally friendly, 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.

EIS Public Meeting 1October 14, 2016



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.


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.


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.

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

  • 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

NOTE: These are the only two technologies available that meet the project’s minimum speed requirement
