I was on Ohau about 10 years ago and stopped by the yard at Ewa. Since it was a weekday there was no one around at Ewa. I also followed the remaining tracks from near Barber's Point along the coast to where they turned up the fenced valley to the ammuntion dump. I think this was near Maili where it turned inland. I have almost everything in print on the OR&L including the Sugars Trains Pictorial book and the TRAINS article in the 1940s but there is no mention of the the Pearl Harbor attack and the impact on the OR&L that day. Almost all of the information is either pre-war or 1942 onward when swarms of GI's showed up on the island. It would be interesting to know the impact of the attack on the railroad.
