  • Provided final design for the traction power system (substations, OCS, corrosion control), train-to-wayside control (TWC) to protect train movements in city streets, communications (CCTV and integration of the bus automatic vehicle location and communications system into the streetcar design), and fare collection


  • The line opened to passengers on July 25, 2014
