Heavy Rail Transit (HRT)
Heavy rail trains operate on tracks so that they are not affected by automobile congestion. Heavy rail trains carry more people and travel at faster speeds than light rail trains, but they are more expensive to build. Typically, trains are powered electrically from a third rail. Heavy rail can operate at ground level, on an elevated structure, or below ground. The frequency of heavy rail is typically 15 minutes or less. Passengers pay to enter stations (not the train itself) which speeds the boarding process. Passengers board from platforms that are level with the train’s floor which helps people of all abilities to board more easily. Stations are typically spaced at least a mile apart, but may be closer together in dense urban areas, such as Downtown or Midtown Atlanta. Stations in urban areas offer access for pedestrians, bicyclists and drop-off passengers. Stations in suburban areas typically offer all of those access options plus parking areas. Stations may offer amenities like ticket vending machines, customer service kiosks, directional signs, real-time train arrival information, etc. MARTA trains are considered heavy rail.
