Further, existing ETS analog wires that are corroded are in violation of Los Angeles City Fire Code Regulations.
The scope of the work includes replacing the entire 24 gauge telephone wires with fiber optic cable along the entire right of way at connection points between passenger stations, traction power substations, and train control and communication rooms. The ETS fiber optic cable will also be integrated with recently upgraded digital Programmable Logic Controllers (PLC) for improved mai...
