The document outlines VTA's plans to enhance light rail service in Mountain View by adding a second track between the Mountain View and Whisman stations, aimed at reducing delays, increasing frequency, and improving connections to Caltrain. The project consists of two phases with projected completion dates in 2014 and 2015, and will incorporate a realignment of Caltrain tracks to accommodate the new light rail track. This initiative is part of VTA's broader light rail efficiency program to meet rising service demands and improve overall transit performance.
