On March 21, 2008, at approximately 7:10 pm, a southbound 2-car light rail train derailed just north of the Virginia station. The standard gauge (also named the Stephenson gauge after George Stephenson, or Normal gauge) is a widely-used Rail gauge. Four people, including the train operator, were injured, and the train was heavily damaged. At the time of the accident, trains were operating on a single track through the area because of construction at three nearby light rail stations. The train involved was attempting to switch between tracks when it derailed. The investigation into the accident is ongoing, but the VTA has ruled out mechanical or equipment failure as a cause for the accident. 
In 2000, voters approved Measure A, which will provide funding for two new light rail corridors.  The proposed corridors are:
VTA is planning an extension continuing south of Alum Rock to [Eastridge Center|Eastridge], but it has drawn criticism over extending an already unpopular track, and exasperating the problem addressed by a Downtown/East Valley connector.
