Passenger trains departed Honolulu every 5 minutes for Pearl Harbor in WW2, and there hasn't been a train on that route for decades. There may be if they ever finish the elevated line...
There were 2 dozen freight trains and a thousand train cars. Honolulu is, has been for a long time, the largest city in the 50 states with no train line, basically since the mid 50s.
