0-6-0 #12 (ALCo-Manchester, 1912) was at the Museum at Ewa for cosmetic restoration the last I knew. I've seen recent photos of it there. 4-6-0 #85 is on Maui at the LK&P undergoinga slow restoration. I understand they want to get it operational in time. ALCo 2-8-2 #60, which was stored on a siding in what was left of the OR&L's Iwilei Yard in Honolulu through 1966 was unfortunately scrapped. HRy. (Big Island) 2-4-2 #5 is somewhere on the east coast, I think, and is probably the only steam locomotive from Hawaii in operable condition, although KRR (Maui) #12 is supposedly close to being operable. Hope this helps. You might want to try the link below for some additional info and photos of OR&L #12 and #85, as well as other, smaller steam power from the Islands.
