The majority of the line, which will serve commuter and general passenger traffic, will be constructed on the route of the existing Hijaz railway between Al-Mahatta station in Amman and Zarqa New Garden City. A three-kilometre extension will take the line along King Abdullah Street to the Raghadan terminal in Amman. The LTRC estimates the system will carry about 45,000 passengers a day in its first year.

A feasibility study was prepared by Austria Rail Engineeringin 1996. The study was updated in 1998 and again in 2003 by Japan’s Padecoand the local Consolidated Consultants.
