There hasn’t been much aloha between the Honolulu Authority for Rapid Transportation and Andrew Robbins toward the end of his role as CEO — unless you remember that the word means “goodbye,” too. That’s what the HART board bid Robbins last week, voting against renewing his contract.

The board’s now in talks with his interim replacement, who will inherit a tough job.

The idea of a quasi-independent rail development agency was insulating the project from politics — though it hasn’t quite played out that way.
