conflict of interest in the planned expansion. Major contractors including Siemens AG, which constructs the train vehicles, contributed substantial amounts of money to the Political Action Committee promoting the expansion referendum. Supporters of an expanded rail system in Houston have leveled similar charges against opponents of the referendum, noting that suburban development interests largely bankrolled the PAC opposing the referendum. In June 2005, Metro announced a revised plan for expansion of the METRORail system. The plan included four new corridors, consisting of both light rail and bus rapid transit. The bus rapid transit lines would have later been converted into light rail when ridership warranted the conversion. On October 18, 2007, the plan was revised to allow for the possibility of more federal funding. Metro decided to have all the lines consist of light rail from the start. The planned expansions are within the city of Houston and will eventually reach the two major Houston airports, George Bush Intercontinental Airport and William P. Hobby Airport. Metro is planning service to suburbs in Houston, as well as other parts of Houston. Alternatives Analysis and Draft Environmental Impact Analysis studies are currently underway on four extensions. Metro is also planning a commuter rail system in conjunction with the light rail system, pending feasibility of the plan. In addition, Metro wants to link up with a planned Commuter Rail line traveling from Fort Bend County to just south of Reliant Stadium, which would use an existing Union Pacific railroad, as well as an additional line branching out along the U.S. Highway 290 corridor to Hempstead, TX and possibly further. A recent entrance by the Gulf Coast Freight Rail District may make the 290 corridor and the Galveston corridor possible by 2012, again pending feasibility. While heavy rail would not be a possibility to serve Fort Bend County, recent approval has been given to study an extension of the Red Line to Fort Bend from the Fannin South Station. Furthermore, Representative Gene Greene has issued a statement regarding a preliminary acquisition of funds for Houston projects, amongst them one million dollars to move forward and extend the Red Line southwest to Missouri City. The passed voter referendum included: Additional of light rail Commuter rail service (28 miles) Increased access to activity centers Rail service to both airports More than 50 new rail stations 50% increase in bus service The following lines and services were
