The pictures show Metro’s traction power crew pulling new high-voltage cables and installing new substations for the Metro Blue Line. This is an ARRA-funded project to replace all 20 Blue Line traction power substations, which power the trains through overhead wires with modern, energy efficient substations.
So far, Metro has replaced 16 substations. The pictures are from the 17th substation at Pacific Coast Highway substation in Long Beach, meaning the project is now approximately 85% complete. Metro has perfected the site work so that the removal and replacement of each substation does not create any major disruptions to Blue Line service.
