Under the terms of Eagle P3, a private company is responsible for designing, building, securing financing, operating and maintaining (
DBFOM) three commuter rail lines, the
East Corridor (later named the
A Line), the
Gold Line (later named the
G Line), and a "starter segment" of the
Northwest Corridor (later named the
B Line). Additionally, the private company would build a maintenance facility for commuter rail equipment that could be used on the lines operated by the contractor, as well as lines directly operated by the RTD. The contract stipulates that the RTD owns all assets involved and collects all revenues generated, while the private contractor assumes all risks involved in the project's operation. In return, the RTD will make monthly payments to the contractor. Eagle P3 is the second full transit DBFOM public-private partnership in the
United States. The first full transit DBFOM public-private partnership in the United States was the
Tren Urbano in
San Juan, Puerto Rico. The involvement of a private sector company was estimated to save about $300 million in construction costs compared to estimates of the cost if the RTD were solely responsible for the project. ==Private partner selection==
