Metrolink Train Controls Operation Support Facility is a Dispatch & Operations headquarters for the Commuter Rail line that serves the Los Angeles Metro area. Since the safety of the entire train system depends upon the Dispatch Center’s ability to operate continually, efficiently, and safely, the Metrolink TCOSF incorporates features such as exterior monitoring & access systems, back-up generators, and enhanced perimeter security. The facility aesthetically enlivens the Garey Avenue corridor of Pomona and is a statement for the agency about the increasing importance of commuter transit in urban life. The design team addressed the varying programmatic concerns including a secured dispatch center and a full data center in a cost-effective, energy efficient way on an extremely compressed, full design schedule of four months.
