Re: C&TS 19 History

Frank, I've seen both 15 and 19 referred to as 0-4-4-0's and B+B's. I think B+B is the preferred usage. Both originally had (and may still have) two Caterpillar V-8 engines. In order to better negotiate the sharp curves (35' radius) on the OR&L, the extra weight of the articulated trucks was a plus. The articulated trucks also supposedly put the stress of the train (cut of cars) behind on the trucks, not on the locomotive's body.
#15 was sold in 1972 to Camino, Cable & Northern RR, Camino, CA, and later the same year to the Colorado Central RR. When it went over to the GLR, I don't know.
#19 went to the C&TS in 1972, direct from the OR&L.
The new book "Next Stop Honolulu!" (Chiddix & Simpson - (c)(p) 2004 Sugar Cane Press) has pictures of both engines appartently switching passenger equipment in Honolulu, probably during or just after WW2. This book also indicates they were ordered for the OR&L. I would guess that the War Department, or the Navy, authorized the purchase, but ownership was always OR&L until 1972 as far as I know.
