Hiya George, Yes, Bill Hatrick is Conductor Bill. I wish I'd have taken his photo this am considering the cool hat he was sporting. Said something like Conductor engraved into brass. Overland Trail is now parked on Garden track at Union Station along with others including Silver Splendor. I recall the location you refer to which is on the Surfline in Anaheim between Main and Batavia, east of Angel Stadium. That was the late 90's around the time 3751 reactivated. No, neither is La Condessa. She was in Fullerton until about 2 years ago. Gone now to a museum?
One or both cars had bee hives inside.
Here are a few photos:
