Nice review, Eric.  I agree that this engine is one of the best of the brass engines produced by Weaver in recent years.  You might have also mentioned that the prototype for this particular engine is still in existence and, in fact, is undergoing restoration at Steamtown in Scranton, PA.  There are plans to have it ready for operation on fan trips sometime soon.  You have a piece of living history right there on your layout!

No, a thermic syphon is not a "type of feed water heater", but a system to circulate water (syphon) from the throat sheet area upward to the crown sheet area. The various feed water heating systems, such as Elesco, Worthington, Sellers, and Coffin to name a few, are all external systems.

 

By the way, that is a very nice review. That beautiful PASSENGER Pacific sure sounds a lot like UP 4-8-4 #844.

Thank you   The  fire box pieces always looked different. I wasn't sure how a thermic syphon worked. I was looking for pictures, couldn't find any quickly.  I believe the fire box has (2) thermic syphons  ?? 

 

I talked to Weaver at the York event.   At that time there were 30 models available from Weaver.  IMO, One of the nicest pieces of Weaver steam I've seen.  IMO.
