The current Metro light rail build-out schedule is as follows (years listed are the years in which service is schedule to start, taken from Metro's web site): 2009: North Extension (University of Houston-Downtown to Northline Mall) 2010: Southeast Line (Downtown to Griggs at Loop 610) 2011: Harrisburg Line (Dowling to the Magnolia Transit Center) 2013: Westpark Line (Wheeler Station to the Hillcroft Transit Center) This is the "First 10-Year Program" of the 25-year Metro Solutions program. Nothing is scheduled yet beyond the four extensions above and of course this schedule is subject to change due to funding, litigation, etc. http://www.ridemetro.org/motion/solutions/plan/tenyear.asp -Eric
