Oct. 30—The rail project's trains are again running after contractor Hitachi Rail Honolulu fixed the problem of doors that were discovered ajar while the automated trains were underway during testing in July.
But another—fixing the ongoing mismatch between too-narrow train wheels on too-wide track switching points—remains elusive, Lori Kahikina, interim CEO and executive director of the Honolulu Authority for Rapid Transportation, told the HART board Friday.
The good news is that the trains have been running since last weekend after Hitachi Rail figured out how to secure the doors.
"The train left the station, and there was a small gap in the doors, so Hitachi has went ahead and fixed that issue, " Kahikina said. "It was a pin that they needed to secure better, so that has been solved. On the platform gates, there were several instances where the train doors and the platform doors did not perfectly align. ... So Hitachi has proposed a software design change to make sure that that does not occur again."
Kahikina told the board that the state Department of Transportation and HART's safety committee have approved the fixes. Each of HART's trains has 24 double sets of doors, and a train is not supposed to be able to run while a door is open.
Addressing the other problem, Hitachi and HART have agreed to replace the trains' narrower wheels with wider ones because the gap between wheels and track is too wide at crossing junctions called frogs.
Kahikina previously told the...
