The first Traction Power Substations for the rail system was installed on schedule in the Rail Operation Center yard on August 1, 2015. The 120,000 lb TPSS was moved from the Honolulu Port at Pier 1 to Port Kealoa in West Oahu, upon it's arrival a police escorted convoy transported it overnight to the ROC, where a crane lifted it and placed into its final position.
This substation is the heart of ROC and will provide electrical power for the driverless movement of trains inside the yard. Each TPSS of the rail system is rated at 3MVA, the power of almost 1,000 households. There are thirteen TPSSs along the mainline and one in the ROC.
Ansaldo Honolulu extends its aloha to the professional support of the Hawaii Department of Transportation and the Honolulu Police Department, as well as to the hard work of its partners Siemens Industry USA, Watts Constructors, and their respective subcontractors ATS International, Pasha Hawaii and Hawaiian Crane and Rigging. This has truly been a team effort!
