What is commuter rail?
Commuter rail a type of heavy rail transit that mostly or entirely uses existing freight and passenger train tracks and is designed primarily for commuters. The frequency of service is typically much less than for light rail, but the cost of starting it is generally far lower because of the minimal amount of construction required and because it is usually not necessary to electrify the line. An example of commuter rail is Sound Transit’s Sounder locomotive-hauled trains currently being operated between Seattle and Tacoma and between Seattle and Everett. Eastside Rail Now! is advocating that the Eastside railroad initially be used for commuter rail.
