WAIPAHU (HawaiiNewsNow) - Grading work for the planned train maintenance and storage facility in Waipahu scheduled to start later this week. HART CEO Dan Grabauskas says the facility will basically house the 'brains and trains' of the rail system. The 43-acre site will be used to store and maintain the rail system's train cars off Farrington Highway between Leeward Community College and Waipahu High School. The site will also house the train control center that will operate the rail system. Grading work at the site will start this week and be done weekdays between the hours of 7 a.m. and 3:30 p.m. While lane closures are not required for this portion of the work, drivers and pedestrians using Ala Ike Street entering Leeward Community College should watch for construction vehicles entering and exiting the construction site.
