Catherine Cruz / HPR There could be another delay to the interim service of Honolulu's rail project. Interim rail authority executive director Lori Kahikina told city council members that during a budget review of the semi-autonomous agency. Kahikina says there is an issue with the wheels of a car and a section called a frog. "On the train, when we have to cross rails, for whatever reasons, it's called a frog. It's where the tracks cross," Kahikina said. "And this crossing, there's five of them on the west side, the wheels that [are] on the cars, it doesn't fit correctly during the crossing."
