What is High Speed Ground Transportation?

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 conscious, and comfortable city- to city- travel at speeds of 120 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 some type of rail system to improve transportation between the two cities.

Several years ago, the corridor was studied as part of the Georgia Department of Transportation’s (GDOT) Intercity Rail Plan. During this study, the corridor was considered as an option for a commuter rail service.

The corridor was then studied by the Atlanta Regional Commission for high-speed rail service as part of a federal initiative to demonstrate magnetic levitation (Maglev) technology in the United States.

The Atlanta-Chattanooga High Speed Ground Transportation (HSGT) study is focusing on the following two HSGT technologies.

Magnetic levitation (MAGLEV)

• Potential speeds over 300 mph
• Average operating speed of 185 mph
• Station spacing 30+ miles
• Grade separated right-of-way
• Electric power to magnets from track
• Magnetic force lifts and propels on guideway

Very high speed rail (VHS)

• Potential speeds near 220 mph
• Average operating speed of 155 mph
• Station spacing 30+ miles
• Grade separated right-of-way
• Electric power from overhead wires to vehicle
• Steel wheel on steel rail
