The Gold Line Phase 2A project extended the LA Metro Gold Line from Pasadena at Sierra Madre Villa Station to Azusa at Citrus College and Azusa Pacific University. The extension added six stations, a maintenance and operations facility, and 11.5 miles to the line. The project opened to the public on-time and on-budget on March 5, 2016. A new, specially designed bridge was conceived and constructed over the Eastbound lanes of the I-210 freeway in order to facilitate the connection from the old terminus in East Pasadena to the new at-grade rail alignment.
B&C Transit Inc. provided detailed design of train control and communications systems for the project which required extensive coordination with other contractors and the agency. B&C Transit Inc. then procured, assembled, wired, tested, and fully configured all of the systems equipment. The alignment parallels a freight trackway in several sections of the route which raised concerns about the possibility of foreign objects entering the light-rail right-of-way. An advanced fiber-optic based object detection system was installed on the fencing that separates the two alignments which was capable of detecting the vibration caused by an object striking the fencing which could lead to foreign material on the light-rail tracks.
