Latest Lionel Big Boy

The jury is still out on that.   There was some disagreement as to if you can actually see the effect, but I believe the stacks are actually plumbed to the different cylinders.

Well you be the judge after watching this video....

 

This question has been answer numerous times since this ( unprototypical) feature was announced. 

 

NO Here is why: Originally posted by HotWater: 

 

The smokebox on any and all steam locomotives is one huge open-on-the-inside cave, so to speak. No matter whether there there are two exhaust nozzles , as on articulateds, or one exhaust nozzle as on two cylinder and three cylinder locomotives, the end result is the exhaust steam/smoke all exists the stack/stacks in unison, i.e. no individual synchronized chuffs.

 

Heres 3985 ( same exhaust setup as a bigboy) "masquerading" as Clinchfield 676. Its even more obvious that the stacks do not chuff independently when the loco is going slow at about the 11;55 mark.

 

 

 

And just to remind ironlake2 and anyone else who might be wondering, you can use your CAB Remote to switch the behavior so that both stacks blow smoke in synch with each other. You get to choose how it operates. 

I was going to ask them how many of them had switched the operation, you beat me to it.

 

what seems strange is changed both stacks to be as one.
yet you still get a double chuff sound now mind you am not thinking it shouldn't be that way but it's just seems odd a double chuff to one burst of smoke.
it's not a deal breaker and in no way am I upset or down talking it.
I like my big boy synced or not it truly is a nice engine.

There are two sets of steam cylinders, so you do get the articulated chuffs, nothing wrong with that.
