Today, Friday, November 17th, Denver's Regional Transportation District opens it's new Southeast Corridor light rail line (PDF flyer). This signifies the completion of the $1.75 Billion T-REX project. Festivities kick off today from 12 Noon to 3 p.m. at the Colorado Station. Festivities are planned to continue at stations along the line tomorrow and free rides on the entire system will be given all day tomorrow. If you're a fan of urban traction, or even a general railfan, it's a great chance to see the 19 new miles of track and explore Denver's southern and central areas. Fares kick in on Sunday, in time for the Broncos game at Mile High Stadium.
