Advocates of modern urban rail began calling on the city of Austin to develop a passenger rail system at the height of the 1970s energy crisis. When voters approved Capital Metro's creation in 1985, the agency was seen not only as the new operator of local bus services, but the developer of a future passenger rail as well. The next year, Capital Metro partnered with the City of Austin to purchase the 162-mile Giddings-to-Llano Austin and Northwestern Railroad on which the Red Line currently operates from the Southern Pacific Transportation Company with the express purpose of someday operating passenger rail on it. The purchase price was $9.3 million, of which $6 million came from a grant from the Federal Transit Administration, $0.6 million came from the City of Austin and $2.7 million came from Capital Metro. On May 20, 1998, Capital Metro acquired the City of Austin's share in the railroad for $1 million.
