The green unit from Santa Clara (aka the one they parted out) is now in Georgetown, CA, in the same collection as the Godchaux 0-6-2 that's been listed with Barnhardt since the days when internet access required a dial tone. Two Baldwin kettles repatriated from the Hawaiian-Philippine Company, as well as the sister engine to the Pacific Coast Railroad's Harpur 4-4-0, are also on the property.
IIRC, the Laughlin thing was built for--but never ran at--one of the Sea World parks and spent much of its early existence warehoused before being sold to the hotel. Tropicana took the place over a few years ago, no clue if the train still runs though.
